Kuyini Ukukhubazeka Kwezokukhiqiza?

Amaphutha okukhiqiza amaphutha okwenzeka ngesikhathi sokukhiqiza, okubangela ukuthi umkhiqizo uphambuke kulokho okuhlosiwe kwedizayini yawo. Ngokungafani neziphambeko zedizayini ezithinta yonke imigqa yomkhiqizo, ukonakala kokukhiqiza kuvame ukuba nomthelela kumayunithi angawodwana noma amaqoqo athile ngenxa yamaphutha enqubweni yokukhiqiza, njengezisetshenziswa ezinephutha, ukungasebenzi kahle kwemishini, noma ukuhlanganisa okungafanele.

Izinhlobo Ezivamile Zokukhubazeka Kwezokukhiqiza

Amaphutha okukhiqiza awela ezigabeni ezimbalwa ezihlukene, ngasinye sinemithelela ehlukile ekusebenzeni nokuphepha komkhiqizo.

Ukukhubazeka kwezintokuvela lapho izinto zokusetshenziswa zihluleka ukuhlangabezana nezidingo ezidingekayo. Izinsimbi ezingekho ezingeni, amapulasitiki angcolile, noma izinhlanganisela ezicutshungulwe ngokungafanele zingaphazamisa ubuqotho besakhiwo. Ucwaningo lwango-2016 lwe-Oak Ridge National Laboratory luthole ukuthi ukungahambisani kwezinto kuma-electrode amabhethri kubangele ukuwohloka komthamo ngokushesha okungama-23% uma kuqhathaniswa namayunithi akhiqizwe kahle.

Ukucubungula amaphuthazenzeka ngezigaba zokukhiqiza ezifana nomshini, ukushisela, noma ukubumba. Lokhu kuhlanganisa ukungalungi kwe-dimensional, ukungapheleli kwendawo, kanye nemihlangano engaphelele. Imisebenzi yokusakaza enembile, isibonelo, ivamise ukulwa namaphutha obukhulu lapho izilawuli zezinga lokushisa ziguquguquka ukudlula ama-degree Celsius angu-2-3 phakathi nezigaba zokupholisa ezibucayi.

Amaphutha ebuswenikubonakala njengokungapheleli okubonakalayo-imihuzuko, amazinyo, ukungahambi kahle kwezingubo, noma ukungcola kwezinhlayiyana. Nakuba ezinye izici ezingaphezulu ziyizimonyo kuphela, ezinye zibonisa izinkinga ezijulile zesakhiwo. Ekwenziweni kwezimoto, ukukhubazeka kokumboza kungadalula izindawo zensimbi ekugqwaleni, kunciphise isikhathi sokuphila sengxenye ngo-40-60%.

Amaphutha omhlanganoumphumela wokubekwa kwengxenye okungalungile, izingxenye ezingekho, noma ukubopha okungafanele. Ukukhunjulwa kwe-airbag ye-Takata ka-2013, okuthinte izimoto ezingaphezu kwezigidi ezingu-100 emhlabeni jikelele, kubangelwa amaphutha enqubo yokuhlanganisa avumele ukungena komswakamo, okubonisa ukuthi ukonakala kokuhlanganiswa kungangena kanjani kube ukwehluleka okuyinhlekelele kwezokuphepha.

Umehluko phakathi kokukhiqiza kanye nokukhubazeka komklamo ubalulekile ngezinjongo zesibopho sezomthetho. Umkhiqizo onesici sokukhiqiza awuzange ube njengoba bekuhlosiwe, kuyilapho iphutha lokuklama lisho ukuthi umkhiqizo wenziwe ngendlela efanele kodwa idizayini ngokwayo ibinamaphutha. Amaphutha okukhiqiza ngokuvamile athinta iphesenti elilinganiselwe lamayunithi, kanti amaphutha edizayini athinta yonke into ekhiqiziwe.

Ukonakala Kokukhiqiza Kumabhethri e-Lithium-Ion

Amabhethri e-Lithium-ion ayisibonelo sokuthi amaphutha okukhiqiza angaguqula kanjani ubuchwepheshe bansuku zonke bube izingozi zokuphepha.Iyini ibhethri ye-lithiumubuchwepheshe? Ibhethri ye-lithium-i-ion isebenzisa ukuhlangana okubuyiselekayo kwe-lithium ion phakathi kwe-anode nezinto ze-cathode ukuze kugcinwe amandla kagesi, okuwenza abaluleke kuma-smartphone, amakhompyutha aphathekayo, nezimoto zikagesi ngenxa yokuminyana kwazo okuphezulu nokushajwa kabusha.

Kodwa-ke, inqubo yokukhiqiza{0}}eyinkimbinkimbi idala amathuba amaningi amaphutha. Ucwaningo lwangoNovemba 2024IsayensiDirectikhombe insimbi yangaphandle-ikakhulukazi izinhlayiya zethusi{1}}njengembangela ehamba phambili yokuhluleka kwebhethri ye-lithium. Lezi zingcolisi ezincane zincibilika ku-electrolyte futhi ziphinde zibeke ezingxenyeni ezibalulekile, zidale amasekhethi amafushane angaphakathi angacupha ukubaleka okushisayo.

Izinkinga ezivamile zokukhiqiza ibhethri ye-lithium zihlanganisa:

Ukungahambi kahle kwe-Electrode coatingzimelela uhlobo lwesici oluvame kakhulu. Ukusetshenziswa okungalingani kwezingubo ze-lithium eziphepheni zethusi noma ze-aluminium kudala izindawo ezishisayo ngesikhathi sokusebenza. Ucwaningo oluvela eLabhorethri Kazwelonke yase-Oak Ridge lubonise ukuthi ama-electrode agglomerates anciphisa ukusebenza kahle komjikelezo ngo-18% kanye nokushesha ukufiphala kwamandla lapho kuminyene khona manje. Izingubo{4}ezingezona ezejwayelekile zibonise u-35% wokuphila komjikelezo ompofu uma kuqhathaniswa nama-electrode akhiqizwe kahle.

Ukungcoliswa kwezinhlayiya zensimbikubeka engcupheni enkulu yokuphepha. Ithusi, insimbi, i-chromium, nezinhlayiya ze-aluminium ezethulwa ngesikhathi sokukhiqiza zingabangela izikhindi zangaphakathi. Ngisho nezinhlayiya ezikala ama-micrometer angu-10-50 zingaqalisa inqubo "yokuhlakazeka + yokubeka" ebeka engozini ubuqotho bebhethri phakathi nezinyanga zokusetshenziswa. Ucwaningo lokutholwa kusetshenziswa i-computed tomography luthole ukungcola ku-3-7% wamaqoqo ebhethri anqatshiwe.

Amaphutha esihlukanisiziyingozi ikakhulukazi. Isihlukanisi{1}}i-membrane enezimbotshana evimbela ukuthintana okuqondile phakathi kwama-electrode{2}}singaba nezimbobo, izinyembezi, noma ukulimala kokuminyanisa phakathi nokuhlanganisa. Imililo ye-Samsung Galaxy Note 7 ibangele isikhala esinganele phakathi kwamaphethelo e-electrode kanye ne-cell casing ezindaweni ezisekhoneni, okubangele ukuchezuka kwama-electrode anwebekayo futhi ancipha izihlukanisi, ekugcineni avumele amasekhethi amafushane.

Amaphutha wokushisela nokuhlanganisakufaka phakathi ama-burrs kumathebhu e-electrode angangena kwi-insulation tape, izitaki zama-electrode ezingaqondani kahle, kanye nokungezwani okungafanele ngesikhathi sokugoqeka kweseli. Ukuhlaziywa kwe-CT scan yamabhethri ahlulekile kwembula ukuthi ama-welding burrs angena ezihlukanisi cishe ngo-12% wamayunithi anesici, axhuma ngokuqondile amathebhu avumayo kubaqoqi bamanje abangalungile.

Imiphumela idlulela ngale kwamadivayisi angawodwana. Ukukhumbula izimoto emhlabeni wonke okuxhunywe nenkinga yebhethri ye-lithium kuthinte izigidi zezimoto zikagesi, kanti i-Samsung's Note 7 recall iyodwa ebiza imali elinganiselwa ku-$5.3 billion. I-UL Research Institutes ibika ukuthi idizayini engafanele nezinqubo zokukhiqiza kumaseli e-lithium{4}}i-ion ingahlala ibambekile kuze kube yilapho icushwa phakathi nokusetshenziswa komkhiqizo, okungase kubangele umlilo, intuthu, nemicimbi yokubaleka okushisayo.

Abakhiqizi manje basebenzisa amasu amaningi okuthola amaphutha. Ukuhlolwa kokwakheka{1}}umjikelezo wokuqala wokushajwa{2}}wokukhulula ngemva kokuvalwa kweseli{3}}kukhomba cishe u-2-4% wamaseli anesici. Izinqubo zokuhlunga ezilandelayo ziqapha amandla kagesi wesekethe evulekile enkathini esukela emasontweni amabili kuya ezinyangeni eziyisithupha, ukubamba amaseli anezici zokuzikhipha ngokwawo ezibonisa amaphutha angaphakathi.

Izimbangela Ezisemuva Kwezinkinga Zokukhiqiza

Ukuqonda ukuthi kungani ukukhubazeka kwenzeka kudinga ukuhlola yonke i-ecosystem yokukhiqiza.

Ukucekelwa phansi kwemishiniumi njengecala eliyinhloko. Imishini yokukhiqiza ihlangabezana nokuguga okuqhubekayo, ilahlekelwa ukunemba ngokuhamba kwesikhathi. Umbiko wekhwalithi yokukhiqiza wango-2024 waphawula ukuthi ukunganakekeli okwanele kokuvikela kuholele ekulahlekeni okunembayo kanye nokwenyuka kwesikhathi sokuphumula, okuhlobana ngokuqondile namazinga aphezulu okukhubazeka. Lapho izigayo ze-CNC zilahlekelwa ukulinganiswa ngezinkulungwane nje zama-intshi, wonke ama-intshi okukhiqiza angawela ngaphandle kokucaciswa kokubekezelela.

Izici zobuntuihlala ibalulekile naphezu kwentuthuko ye-automation. Abahloli abasebenza ngezandla basebenza ngaphansi kwengcindezi enkulu, bahlola izinkulungwane zamayunithi nsuku zonke. Iso lomuntu, nakuba liyinkimbinkimbi, lihlushwa ukukhathala kanye nokuchema kokuqonda. Ngokohlaziyo lwango-2024, abakhiqizi basathembela kakhulu ekuhlolweni komuntu naphezu kokuthuthukiswa kokubona komshini, okuholela ekuphunyukeni kwamaphutha ekubonweni ezindaweni zokuhlola ezibucayi zokulawula ikhwalithi.

Ukuhluka kwenquboyethula ukungezwani ngisho nasezindaweni{0}ezilawulwa kahle. Ukushintshashintsha kwezinga lokushisa ngesikhathi sokwelapha, izikhathi zokuxutshwa ezingahambisani zokuhlanganisa ama-slurries, noma isivinini esishintshashintshayo sokuthutha konke kunomthelela ekulimaleni. Ekwenziweni kwe-electrode yebhethri ye-lithium, ukuhluka kwamazinga okudla okudaka noma isikhathi esinganele sokuxuba sokufeza izingxube ezilinganayo kubangela ukwakheka kwama-agglomerate.

Izinkinga zekhwalithi yochungechunge lokuhlinzekanwebisa izingozi zokukhubazeka ngale kwezindonga zasefekthri. Ukungcola kwempahla eluhlaza, izingxenye ezisezingeni eliphansi ezivela kubahlinzeki besigaba 2 noma isigaba-3, nokungcoliswa ngesikhathi sokuthutha konke kwethula imithombo yokukhubazeka. Ubuchwepheshe be-Blockchain buya ngokuya busetshenziswa ukuze kulandelelwe izinto ezisetshenziswa kuwo wonke amaketanga okunikezwayo emhlabeni jikelele, kodwa izikhala zisekhona, ikakhulukazi kubahlinzeki abangagcini izindinganiso zekhwalithi eziqinile.

Izici zemvelodlala indima ethathwa kancane. Izinhlayiya zothuli ezindaweni zokukhiqiza, ukuhlukahluka komswakamo, kanye noshintsho lwezinga lokushisa elizungezile lungangenisa ukungcola noma luthinte izakhiwo zentokozo.

I-Six Sigma methodology, eyathuthukiswa yi-Motorola ngawo-1980, yasungula ukuthi{1}}izinqubo zekhwalithi ephezulu ngempela zithola ukukhubazeka okungu-3.4 ngesigidi samathuba (okubalwa ku-1.5 sigma process drift). Nokho, ukufeza leli zinga kudinga ukubhekana nazo zonke lezi zimbangela zezimpande ngendlela ehlelekile kunokwelapha izimpawu.

Umthelela Wezezimali Nokuphepha

Amaphutha okukhiqiza anemiphumela enwebeka kakhulu ngale kokulahlekelwa kokukhiqiza okusheshayo.

Izindleko zezimali eziqondilehlanganisa ngokushesha. Izinto ezilahliwe, ukusetshenzwa kabusha, kanye nesikhathi sokuphumula sokukhiqiza kudala ukulahlekelwa okubambekayo. Lapho ukonakala kufinyelela amakhasimende, izimangalo zewaranti, ukushintshwa kwemikhiqizo, kanye nokukhumbula izinto ezisetshenziswayo kuphindaphinda izindleko ngokukhula. Uhlaka Lwezindleko Zekhwalithi Empofu (i-COPQ) lulinganisa le mithelela{3}}izinkampani ezinezilinganiso zokukhubazeka eziphezulu zivame ukuthola ukuthi{4}}izindleko ezihlobene nekhwalithi zisebenzisa u-15-20% wemali engenayo.

Khumbula ezomnothoibonisa ubungozi bezezimali obudlulele. Ngo-2022, amayunithi emikhiqizo angaphezu kwezigidigidi eziyi-1.5 kuwo wonke ukudla, izidakamizwa, izinsiza zezokwelapha, izimoto, kanye nezimpahla zabathengi. Okuhlangenwe nakho kwemboni yezimoto ngama-airbag e-Takata angasebenzi kuphoqe umenzi ukuthi aphelelwe imali lapho izibopho zesinxephezelo zidlula amaRandi ayizigidi eziyizinkulungwane ezingu-9. Iyunithi ngayinye ebuyisiwe ingena ezindlekweni zokuhlonza, zesaziso, zokumiselela, nezokuthutha.

Ukuchayeka kwesibophokudala ukungaqiniseki kwezezimali okuqhubekayo. Ngaphansi kwemfundiso eqinile yesibopho sezomthetho, abakhiqizi babhekana nesibopho sokulimala okudalwe imikhiqizo enesici kungakhathaliseki ukuthi budedengu. Izivumelwano ezisemthethweni nezahlulelo zokulimala komuntu zingafinyelela ezigidini ngecala ngalinye, ikakhulukazi uma ukukhubazeka kubangela ukulimala okuyinhlekelele. Amacala ezinyathelo zekilasi akhulisa lezi zingozi kakhulu.

Ukulimala kwesithunzikudala-ukuguguleka kwesimo semakethe sesikhathi eside. Ukwethenjwa kwabathengi, uma sekwephukile, kubonakala kunzima ukukwakha kabusha. Ucwaningo lwemibono yomkhiqizo lubonisa ukuthi ukwehluleka kwekhwalithi kunganciphisa inhloso yokuthenga ngo-30-50% phakathi kwamasegimenti ekhasimende athintekile, izikhathi zokutakula ezinwebeka iminyaka engu-3-5 ngisho nangemva kokusetshenziswa kwezinyathelo zokulungisa.

Imiphumela yokuphephaOkubaluleke kakhulu emikhiqizweni yabathengi namathuluzi ezimboni. Imishini yezokwelapha engalungile, izingxenye zendiza, noma amasistimu ebhethri angabangela ukulimala noma ukufa. Ukonakala kwebhethri kudala ubungozi bomlilo kanye nokuqhuma-ngenkathi izinga lokusha lihlala liphansi cishe kumayunithi amathathu esigidini ngasinye, imiphumela yezehlakalo zokuphelelwa umoya zinzima ngokwanele ukuthi ziqhube ukutshalwa kwezimali kokulawula ikhwalithi.

Icala lezomnotho lokuvimbela ukukhubazeka liyacaca uma kuqhathaniswa nezindleko. Ukuthola nokulungisa iziphambeko kumthombo wezindleko cishe u-10% wokubhekana nazo-zokukhiqiza.

Ukuhlela ukunakekelwa okusekelwe esimweni sangempela semishini kunezikhawu ezimisiwe kunciphisa isikhathi sokuphumula esingahleliwe ngo-30-50% kuyilapho kugcinwa ukunemba kokukhiqiza.

Ukuqeqeshwa kwabasebenzi nokuzibandakanyaikhuluma ngezinto zomuntu ngendlela ehlelekile. Izinhlelo eziqhubekayo zokuqeqesha ezinkambisweni ezifanele, izindinganiso zekhwalithi, nokubonwa kokukhubazeka kunciphisa amaphutha omqhubi. Amasistimu angokoqobo okungathandwa kwabathelisi esikubona manje anikeza{2}}isiqondiso sesikhathi sangempela phakathi nemisebenzi eyinkimbinkimbi yokuhlanganisa, emboza imiyalelo yedijithali ezindaweni zokusebenza ezibonakalayo. Izinkampani ezitshala imali ekuqeqesheni okuphelele zibika ukuthuthukiswa okungama-25-35% kwenzuzo yokudlula kuqala.

Ukumisa inqubo nokulawulakunciphisa ukushintshashintsha. Izimiso zokukhiqiza ezinciphile ziqeda izinyathelo zenqubo ezingadingekile ngenkathi kuqinisa ukubekezelelana kumapharamitha abalulekile. Ngokufakwa kwe-electrode yebhethri ye-lithium, ukulawulwa okunembile kwe-slurry viscosity, isivinini sokumboza, namaphrofayili okushisa okomisa kunciphisa amazinga okukhubazeka ukusuka ku-5-7% kuya ngaphansi kuka-2%. Ukulawulwa kwenqubo yezibalo kunikeza uhlaka lokulinganisa lokugcina lezi zilawuli eziqinile.

Ukuphathwa kwekhwalithi yomhlinzekiinweba ukuvimbela ukuya phezulu. Ukwenza ukucwaninga okujwayelekile kwabahlinzeki, ukusebenzisa izivumelwano zokuhlola impahla engenayo, kanye nokusungula izivumelwano zekhwalithi kuqinisekisa ikhwalithi yezinto ezingavuthiwe ezingashintshi. Abanye abakhiqizi bahlanganisa abahlinzeki ezinhlelweni ezihlanganyelwe zokuthuthukisa, ukwabelana ngedatha nokuhlanganyela ekunciphiseni amaphutha. Ukushintshela kubahlinzeki abathembeke kakhulu, uma kudingekile, ngokuvamile kufakazela izindleko ezengeziwe{3}ezisebenza kahle kunokuphatha isici{4}}sezinto ezivamile.

I-Design for Manufacturability (DFM)ivimbela amaphutha ngaphambi kokuqala kokukhiqiza. Izimiso ze-DFM zithuthukisa imiklamo yomkhiqizo ukuze kube lula ukwenziwa, inciphisa amathuba amaphutha okuhlanganisa kanye nezindaba zokusingatha izinto. Ekwakhiweni kwebhethri, ukunikeza isikhala esanele phakathi kwamaphethelo e-electrode nama-cell casings kuvimbela uhlobo lwesici esibangele umlilo we-Galaxy Note 7.

Ubuchwepheshe be-Digital twininika amandla ukuhlola okubonakalayo kanye nokwenza kahle. Ukudala izifaniso ezibonakalayo zezinqubo zokukhiqiza kuvumela onjiniyela ukuthi balingise izimo ezinokukhubazeka kanye nokuthuthukiswa kwenqubo yokuhlola ngaphandle kokuphazamisa ukukhiqiza. Abakhiqizi bebhethri basebenzisa amawele edijithali ukuthuthukisa amaphethini okunamathela e-electrode, babikezele ukwakheka kokukhubazeka, futhi baqinisekise izinqubo ezintsha zokuhlanganisa ngaphambi kokuqaliswa kokusebenza ngokomzimba.

Amasu okuvimbela aphumelela kakhulu ahlanganisa lezi zindlela zibe izinhlelo ezihlanganisiwe. Ucwaningo lwekhwalithi yokukhiqiza lwango-2025 lwathola ukuthi izinkampani ezisebenzisa okungenani amasu okuvimbela amahlanu ngesikhathi esisodwa zehlisa izilinganiso zokukhubazeka ngo-60-75% enkathini yeminyaka emithathu, kuyilapho lezo ezigxile endleleni eyodwa zithole ukuthuthukiswa okungama-20-30%.

imibuzo ejwayelekile ukubuzwa

Zivame kangakanani izinkinga zokukhiqiza ekukhiqizeni kwesimanje?

Izilinganiso zokukhubazeka ziyahlukahluka kakhulu ngemboni kanye nobunkimbinkimbi bomkhiqizo. Izinqubo ezi-Six Sigma ziqondise ekushiyekeni okungu-3.4 ngamathuba ayisigidi, nakuba abakhiqizi abaningi besebenza ku-3-4 amazinga we-sigma (6,200-45,500 amaphutha ngesigidi ngasinye). Ama-electronics abathengi ngokuvamile afinyelela amazinga okukhubazeka angu-0.2-0.5%, kuyilapho izimboni ezibaluleke kakhulu kwezokuphepha ezifana ne-aerospace zihlose amanani angaphansi kuka-0.01%. Ngo-2022, amayunithi emikhiqizo angaphezu kwezigidigidi eziyi-1.5 akhunjulwa emhlabeni wonke, okubonisa ukuthi amaphutha ayaqhubeka nokuthinta amanani abalulekile wokukhiqiza naphezu kokuthuthuka kwekhwalithi.

Uyini umehluko phakathi kwamaphutha okukhiqiza kanye namaphutha edizayini?

Ukonakala kokukhiqiza kwenzeka uma umkhiqizo ungafani nomklamo wawo ohlosiwe ngenxa yamaphutha okukhiqiza, okuthinta kuphela amayunithi athile kunqwaba. Amaphutha edizayini asho ukuthi umkhiqizo wakhiwe ngendlela efanele kodwa umklamo ngokwawo unamaphutha ngokwemvelo, uthinta yonke iyunithi ekhiqiziwe. Ngesibopho sezomthetho, abakhiqizi bangathweswa icala eliqinile lokulimala kokukhiqiza ngaphandle kokufaka ubudedengu, kuyilapho amacala okungasebenzi kahle kwedizayini edinga ukukhombisa ukuthi eminye imiklamo ephephile ibingenzeka.

Ingabe amaphutha okukhiqiza angabonwa ngaphambi kokuba imikhiqizo ifinyelele amakhasimende?

Eziningi kodwa akuzona zonke iziphambeko ezingabanjwa ngokulawulwa kwekhwalithi. Izindlela zokuthola ezithuthukisiwe ezifana nokuskena kwe-CT, ukubona komshini, nokuhlola kukagesi kukhomba u-90-95% weziphambeko ezibalulekile. Kodwa-ke, okunye ukukhubazeka kuhlala kufihlile noma kubonakala kuphela ngaphansi kwezimo ezithile zokusetshenziswa. Kumabhethri e-lithium, ukuhlola ukwakheka kanye nezinqubo zokuguga zibamba cishe u-96-98% wamaseli anesici, kodwa ukukhubazeka okucashile kungase kuvele kuphela ngemva kwezinyanga zokusebenza. Yingakho ukuthuthukiswa okuqhubekayo kobuchwepheshe bokuthola kusabalulekile.

Yini okufanele abathengi benze uma bethola isici sokukhiqiza?

Bhala iphutha ngezithombe futhi ugcine umkhiqizo esimweni sawo sokonakala. Xhumana nomkhiqizi noma umdayisi ngokushesha ukuze ubike udaba futhi ubuze mayelana nezinketho zokumiselela noma zokubuyiselwa imali. Ngemikhiqizo ebeka engcupheni yezokuphepha-ikakhulukazi amabhethri, izinto zikagesi, noma izingxenye zesakhiwo-yeka ukusebenzisa ngokushesha. Uma isici sibangele ukulimala noma ukulimala kwempahla, thintana nezingcweti zezomthetho mayelana nezimangalo zesikweletu somkhiqizo. Bika amaphutha angathi sína kuma-ejensi afanele okuvikela abathengi ukuze usekele ukukhumbula okungenzeka futhi uvikele abanye abathengi.

Amaphutha okukhiqiza ahlala eyinselele engagwemeki ezindaweni zokukhiqiza, kodwa ukuvama kwawo nomthelela kungancishiswa kakhulu ngokuphathwa kwekhwalithi okuhlelekile. Ukuvela kokuvela ekuhlolweni okusebenzayo kuye ekuvimbeleni okubikezelwayo kumelela uhambo oluqhubekayo lokukhiqiza oluya kukhwalithi ephezulu nokuphepha okukhulu.

Kubakhiqizi bebhethri ngokukhethekile, iziteki ziyaqhubeka zikhuphuka njengoba ubuchwepheshe be-lithium-ion bunwebeka kwezinye izinhlelo zokusebenza. Ukuthuthukiswa okuqhubekayo ngakunye kokutholwa kokukhubazeka nokuvimbela kuhumusha ngokuqondile emikhiqizweni ephephile futhi kugwenywe ukukhumbula-ukwenza ukulawulwa kwekhwalithi hhayi nje ukukhathazeka ngokukhiqiza kodwa okubalulekile kwebhizinisi okubalulekile.

Okuthathwayo Okubalulekile

Amaphutha okukhiqiza amaphutha okukhiqiza adala ukuthi imikhiqizo iphambuke kulokho okuhlosiwe, ngokuvamile athinta amayunithi ngamanye kunemigqa yonke yomkhiqizo.

Amabhethri e-Lithium-ion abhekana nezingozi ezihlukile zokukhubazeka okuhlanganisa ukungcoliswa kwensimbi, ukungalungi kwe-electrode coating, kanye nokulimala kwesihlukanisi okungabangela ukubaleka kokushisa.

I-Root ibangela ukuwohloka kwemishini ye-span, izici zomuntu, ukuhlukahluka kwenqubo, izinkinga ze-supply chain, kanye nezici zemvelo

Ubuchwepheshe bokubona obuthuthukisiwe obufaka ukuskena kwe-CT,{0}}amasistimu okubona anamandla e-AI, kanye ne-infrared thermography manje kuhlonza amaphutha ngokunemba okungu-98.5%.

Amasu okuvimbela ahlanganisa Amasistimu Okuphatha Ikhwalithi, ukunakekelwa okubikezelwayo, kanye ne-Design for Manufacturability kunciphisa amazinga okukhubazeka ngo-60-75%
