Iyini i-Graphite Anode?

I-graphite anode i-electrode engeyinhle ku-aibhethri ye-lithium ion, eyenziwe ngekhabhoni ehlelwe ngamashidi anezingqimba agcina futhi akhulule ama-ion e-lithium ngesikhathi sokushaja nokukhipha. Isebenza njengento eyinhloko yokusingatha lapho kufakwa khona ama-ion e-lithium phakathi kwezendlalelo ze-graphite lapho ibhethri lishaja, okubalela u-10-20% wesisindo esiphelele sebhethri.

Ukusebenza kwe-graphite njenge-anode kuvela ekwakhiweni kwayo kwe-athomu. Ibhondi yama-athomu ekhabhoni kumashidi ayisicaba, anama-hexagonal abizwa ngokuthi izendlalelo zegraphene, anqwabelene phezu kwelinye ngesikhala esingu-3.354 ama-angstrom. Amandla e-Weak van der Waals abamba lezi zendlalelo ndawonye{3}}ziqine ngokwanele ukugcina ukwakheka, kodwa zibuthakathaka ngokwanele ukuvumela ama-ion e-lithium ashelele phakathi kwazo.

Lesi sakhiwo esinezingqimba sidala izindlela zemvelo zokuhamba kwe-ion. Uma ibhethri lishaja, ama-ion e-lithium asuka ku-cathode ngokusebenzisa i-electrolyte futhi azishumeke phakathi kwezingqimba ze-graphite ngenqubo ebizwa ngokuthi i-intercalation. Isikhala phakathi kwezingqimba sikhula cishe ngo-10% ukuze kufakwe la ma-ion. Lapho ibhethri liphuma, ama-ion aphuma ku-graphite abuyele ku-cathode, akhiphe amandla agciniwe.

I-graphite yakha lokho abacwaningi abakubiza ngokuthi i-lithium-i-graphite intercalation compounds (Li-GICs) ngezigaba ezahlukene. Uma ishajwe ngokugcwele, i-anode ifinyelela ekwakhiweni kwe-LiC₆{3}}i-athomu ye-lithium eyodwa kuwo wonke ama-athomu e-carbon ayisithupha-omele ubukhulu besitoreji sokuminyana kwegraphite engafinyelelwa.

I-graphite ibusa izinto ze-anode zebhethri ngenxa yezizathu ezidlula ukutholakala kalula. Umthamo wayo wetiyetha ufinyelela ku-372 mAh/g, iletha ukusebenza okuthembekile ezinkulungwaneni zemijikelezo yokushaja. Okubaluleke nakakhulu, i-graphite isebenza ngamandla aphansi e-electrochemical angu-0.01-0.2 V uma iqhathaniswa ne-Li/Li⁺, ekhulisa umehluko we-voltage phakathi kwe-anode ne-cathode, ehumusheka ngokuqondile ekumineni kwamandla aphezulu kuseli eliphelele lebhethri.

Isibambo sevolumu sishintsha kahle. Ngokungafani nezinye izindlela ezinwebeka kakhulu ngesikhathi se-lithiation, ukwakheka kwe-graphite kuthwala ama-ion e-lithium anokuvuvukala okuncane-ngokuvamile ngaphansi kuka-10%. Lokhu kuzinza kwesakhiwo kuchaza ukuthi kungani ama-graphite anode evamise ukweqa imijikelezo yokushaja eyi-1,000 ngokuwohloka komthamo omncane.

Izindleko zidlala indima ebalulekile. I-graphite yemvelo evela emisebenzini yezimayini kanye ne-synthetic graphite evela ku-petroleum coke kokubili kunikeza izindleko zokukhiqiza ezingaphansi kakhulu kwezinye izinto. Kusukela ngo-2024, i-graphite yemvelo eyindilinga ithengisa cishe u-$7,000 ngethani ngalinye uma kuqhathaniswa ne-synthetic graphite ngo-$10,000 ngethani. Okubalulekile kudinga amazinga okuhlanzeka adlula u-99.95% wezinhlelo zebhethri, afinyelelwa ngezinqubo zokuhlanza okuthi, nakuba{9}}kumandla amakhulu, ahlale esebenza ngokwezomnotho esikalini.

Ukucatshangelwa kokuphepha nakho kuthanda i-graphite. Isendlalelo esiqinile se-electrolyte interphase (SEI) esakheka ezindaweni zegraphite ngesikhathi sokushaja kokuqala sisebenza njengesivikelo esivikelayo, sinqande ukubola kwe-electrolyte okuqhubekayo kuyilapho sivumela ukuthuthwa kwe-lithium ion. Lesi sici sokuzivikela,{2}}esatholwa abacwaningi ngo-1990 besebenzisa i-ethylene carbonate electrolyte, senza ukusebenza kwezentengiselwano kwe-graphite anode futhi kwabangela ukuguquguquka kwebhethri ye-lithium{4}}okulandelayo.

Graphite Anode

Imboni yebhethri ithola i-graphite ngemizila emibili ehlukene, ngayinye enezinzuzo ezithile.

I-graphite yemvelo isuka ku-flake crystalline deposits ekhishwa ngezimayini, ikakhulukazi e-China, e-Brazil, e-Madagascar, nase-India. Abakhiqizi bacubungula i-flake graphite eluhlaza ngokuchotshozwa, i-spheroidization-lapho amandla emishini enza ama-flakes angajwayelekile abe yizinhlayiya eziyindilinga{2}}nokuhlukaniswa, kanye nokuhlanza ukuze kufinyelelwe{3}}izicaciso zebanga. Ukukhiqizwa kwe-graphite yemvelo kudla cishe u-1.1 × 10⁴ MJ ngethani lamandla.

Isinyathelo se-spheroidization sibonakala sibucayi. Ukusebenza kwebhethri kuyathuthuka ngezinhlayiya eziyindilinga ngoba zipakishwa ziminyene kakhulu kuma-electrode, akhulisa ukuminyana kwamandla evolumu futhi athuthukise ukuhamba kukagesi kuso sonke isakhiwo se-anode. I-graphite yemvelo ivamise ukukhombisa ubucwebe obuphakeme kunezinye izindlela zokwenziwa, ezihlinzeka ngokusebenza okuphezulu kukagesi nokushisayo.

I-synthetic graphite iqala ku-petroleum coke, inaliti coke, noma i-pitch coke-imikhiqizo yokucwenga uwoyela. Abakhiqizi bashisisa lezi zenduleli zekhabhoni emazingeni okushisa angaphezu kuka-2,500℃ngesikhathi se-graphitization, belungisa kabusha ama-athomu ekhabhoni endaweni ehlelekile, enezingqimba ewuphawu lwegraphite. Le nqubo idinga cishe u-4 × 10⁴ MJ ngethani-3.6 izikhathi zesidingo samandla sokukhiqizwa kwe-graphite yemvelo.

Nokho, i-synthetic graphite iletha izici ezingaguquki. Inqubo yokukhiqiza elawulwayo ikhiqiza osayizi bezinhlayiyana ezifanayo kanye nokuziphatha okubikezelwa kwe-electrochemical, abakhiqizi bebhethri ababaluleke kakhulu ekulawuleni ikhwalithi. Njengamanje, imboni ihlukanisa cishe u-55% wokwenziwa kanye no-45% we-graphite yemvelo yokukhiqiza i-anode, nakuba le bhalansi ishintsha njengoba ukuhlanzwa kwe-graphite yemvelo kuba ngcono.

Ngo-2020, izinto zemvelo ze-graphite anode zathatha ama-39% emakethe, nokuqagela okukhombisa ukukhula okuqhubekayo okuqhutshwa umthelela ophansi wemvelo kanye nokunciphisa ukusetshenziswa kwamandla ngesikhathi sokukhiqiza.

Ukutholwa okusabalele kwe-graphite kumaski umkhawulo obalulekile wokusebenza: ukushaja okusheshayo. Uma amabhethri eshaja ngokushesha, ama-ion e-lithium afika endaweni ye-anode ngokushesha kunalokho angangena esakhiweni segraphite. Ama-ion amaningi abe esefaka endaweni ye-anode njenge-metallic lithium{2}}isenzakalo esibizwa ngokuthi i-lithium plating.

I-lithium plating idala izinkinga eziningi. Insimbi epuletiwe ayifaki isandla kumthamo webhethri, yehlisa ngempumelelo isitoreji samandla esitholakalayo. Okuningi mayelana, ukucwenga okuphindaphindiwe nokuhlubula kulimaza isakhiwo se-anode futhi kudle i-electrolyte ewuketshezi, kusheshise ukufiphala kwamandla. Ezimweni ezimbi kakhulu, i-lithium dendrites ingakhula ngokusebenzisa isihlukanisi phakathi kwama-electrode, okubangela izifunda ezimfushane zangaphakathi.

Imbangela eyinhloko ilele ku-lithium diffusion kinetics. Ukufaka ama-ion e-lithium phakathi kwezingqimba ze-graphite kudinga ukuthi banqobe izithiyo zamandla njengoba besuka ku-electrolyte beya esakhiweni esiqinile. Ngaphansi kwamazinga aphakeme amanje, i-concentration polarization ithuthukisa-i-lithium concentration endaweni ye-anode idlula lokho okungakudonsa, okwenza amandla abe phansi ngokwanele ukuze acwebe i-metallic lithium esikhundleni salokho.

Abacwaningi babhekana nale mikhawulo ngokusebenzisa izindlela eziningi. Izembatho ezingaphezulu zisebenzisa i-amorphous carbon noma i-lithium{1}}izinto zokwenziwa kwe-ion zidala ukusabalalisa kwe-lithium okufanayo kanye nokuthutha kwe-ion okusheshayo endaweni yegraphite. Ukuthuthukisa i-Electrolyte ngezithasiselo ezithile kusiza ukwakha izendlalelo ze-SEI ezizinzile ezisiza ukudluliswa kwe-ion. Abanye abakhiqizi bashintsha i-graphite particle morphology noma bakhulise isikhala se-interlayer ukuze kusheshiswe ukusakazeka kwe-lithium.

Ucwaningo lwakamuva ngo-2024 lubonise ukuthi ama-graphite anode anama-coatings athuthukisiwe kanye nokwakheka kwe-electrolyte angakwazi ukusekela amanani wokushaja afinyelela ku-6C (ukushaja okugcwele emizuzwini eyi-10) kuyilapho igcina impilo yomjikelezo engaphezu kwemijikelezo engama-500. Kodwa-ke, lokhu kusalokhu kuyindawo esebenzayo yentuthuko njengoba abakhiqizi bezimoto zikagesi bekhomba amandla okushaja asheshayo.

Graphite Anode

I-Silicon-ama-anode asuselwa ku-silicon amele inselele enkulu ekubuseni kwe-graphite, eqhutshwa amandla e-silicon aphakeme ngokumangalisayo angu-4,200 mAh/g{3}}ngaphezu kokuphindwe kashumi kune-graphite. Le nzuzo yomthamo isukela ekhonweni le-silicon lokuhlangana nama-athomu e-lithium angu-4.4 nge-athomu ye-silicon ngayinye (Li₄.₄Si), kuyilapho i-graphite idinga ama-athomu ekhabhoni ayisithupha ukuze ahlangane ne-lithium ion eyodwa.

Isikhalazo sisobala. Ukushintsha ngisho no-10-20% we-graphite nge-silicon kungakhuphula ukuminyana kwamandla ebhethri ngo-10-30%, kuhumushele ngqo ibanga elide lokushayela ezimotweni zikagesi. Iziqalo ezimbalwa kanye nabakhiqizi abakhulu batshale imali eningi ekuthuthukisweni kwe-silicon anode, nezinkampani ezifana ne-Sila Nanotechnologies kanye ne-BMW ezisebenzisanayo ezicelweni zentengiso ezihloselwe maphakathi nawo-2020.

Kepha inzuzo ye-silicon iza nephutha elibalulekile: ukunwetshwa kwevolumu. Izinhlayiya ze-silicon zivuvukala ngaphezu kuka-300% ngesikhathi se-lithiation, uma kuqhathaniswa ne-graphite eyi-10%. Lokhu kwanda okukhulu kuphuka izinhlayiya, kuphazamise ukuxhumana kukagesi, futhi kuthuntubeze ungqimba lwe-SEI. I-anode iyazicoboshisa ngokusebenza okuvamile, okubangela ukufiphala kwamandla ngokushesha. Ama-silicon anode okuqala asinda ngokulambisa emijikelezweni yokushaja eyi-100.

Onjiniyela bakha izixazululo. I-silicon ye-nanostructured-izinhlayiya esikalini se-nanometer{2}}ithwala kangcono izingcindezi zokunwetshwa. Izakhiwo ze-silicon ezinama-porous zinikeza isikhala esingenalutho sangaphakathi sokunwetshwa. I-Silicon oxide (i-SiOx) inikeza ukuyekelela ngomthamo wethiyori ongu-2,675 mAh/g kanye nokunwetshwa okuncishisiwe uma kuqhathaniswa ne-silicon emsulwa. Izibophezelo ezithuthukile{8}}izinto ezibamba izinhlayiya ze-anode ndawonye{9}}zihlanganisa izici ezinwebekayo ukuze kugcinwe ukuxhumana kukagesi ngesikhathi sokushintsha kwevolumu.

Izinhlanganisela ze-silicon-ze-graphite okwamanje zimele indlela esebenza kakhulu kwezohwebo. Ngokuhlanganisa u-5-15% we-silicon kuma-graphite anode, abakhiqizi bathola ukuthuthukiswa komthamo okuphusile kuyilapho bekhawulela imiphumela elimazayo yokunwetshwa kwe-silicon. Lelisu eliyingxubevange liletha ukuminyana kwamandla okuphezulu okungu-15-20% kune-graphite anode emsulwa kuyilapho igcina impilo yomjikelezo ongu-500-800 eyamukelekayo ezinhlelweni eziningi.

Izindleko zihlala ziyisithiyo esibalulekile. I-silicon-i-anode eyinhlanganisela yekhabhoni ibiza cishe u-750,000 CNY ngethani ngo-2024, uma kuqhathaniswa no-50,000-100,000 CNY ngethani lama-graphite anode. Abahlaziyi bemboni benza izinto zokwakha ze-silicon anode zidinga ukuncishiswa kwezindleko ziye ku-110,000-170,000 CNY ngethani ukuze zamukelwe kabanzi ngokwezentengiselwano.

Imakethe ye-graphite anode ikhula kakhulu. Ilinganiselwa ku-$11.9 billion ngo-2022, ukuqagela kwezimboni kulinganisela ukuthi imakethe izofinyelela ku-$50.83 billion ngo-2030, okumelela izinga lokukhula elihlanganisiwe lonyaka lika-19.9%. Lokhu kunwetshwa kulandelela ngokuqondile ukusetshenziswa kwemoto kagesi kanye{7}}nokusetshenziswa kwesikali sesitoreji samandla segridi.

Ukunikezwa kwe-dynamics kudinga ukunakwa. Ibhethri ngalinye lemoto kagesi liqukethe u-50-100 kg wegraphite-cishe igraphite ephindwe kashumi kune-lithium. I-Tesla Model S eyodwa, isibonelo, idinga cishe u-85 kg we-graphite ngephakethe layo lebhethri. Ukukhiqizwa kwe-Global EV kukhula ngokushesha, izimoto zikagesi zibalwa ngephesenti elikhulayo lokuthengiswa kwezimoto.

I-China ibusa amaketanga okunikezwa kwe-graphite, ilawula kokubili izimayini ze-graphite zemvelo kanye nokukhiqizwa kwe-graphite yokwenziwa. Lokhu kugxila kuphakamise ukukhathazeka kokuvikeleka phakathi kwabakhiqizi bebhethri kwezinye izifunda. Imikhawulo yaseChina yango-2023 yokuthumela ngaphandle kwezinto ze-graphite yakhulisa lokhu kukhathazeka, okwashukumisela amazwe aseNtshonalanga ukuthi atshale imali ekuthuthukiseni amakhono okukhiqiza ama-graphite asekhaya kanye nokucubungula.

Inqubo yokuhlanza imele umshayeli wezindleko oyinhloko. Ukuguqula i-graphite yemvelo embiwa ibe yibhethri-okubalulekile kudinga ama-asidi aqinile nezinyathelo eziningi zokucubungula, okudala ukucatshangelwa kwemvelo. Kodwa-ke, ingqikithi ye-carbon footprint yokukhiqizwa kwe-graphite yemvelo ihlala iphansi kakhulu kune-synthetic graphite, ngokuyinhloko ngenxa yenqubo-enamandla ye-graphitization edingekayo ezintweni zokwenziwa.

Ukugaywa kabusha kuveza kokubili ithuba kanye nenselelo. Amabhethri e-lithium-e-ion athathe umhlalaphansi aqukethe inani elikhulu le-graphite-ngokuvamile u-40-ongu-50% we "black mass" etholiwe emisebenzini yokugaya kabusha. Nokho, ukukhipha kanye{6}}kuhlanza kabusha le graphite kubhethri-izicaciso zebanga kuhlala kunzima ngokobuchwepheshe futhi kuncane ngokomnotho ezikalini zamanje. Abacwaningi bathuthukisa izinqubo zokuvuselela kabusha ezisebenza kahle kakhulu, beqaphela ukuthi ukutholwa kwe-graphite evaliwe kuzoba okubaluleke kakhulu njengoba amavolumu ebhethri ekhula.

Ngenkathi amabhethri e-lithium-i-ion amelela ukusetshenziswa okukhulu kwe-graphite anode, okokusebenza kusebenza kwamanye amasistimu e-electrochemical. Kumaseli kaphethiloli, ikakhulukazi i-proton exchange membrane fuel cell (PEMFCs), i-graphite yakha amapuleti enkundla yokugeleza kwe-cathode asabalalisa umoya-mpilo ngokulinganayo ezindaweni zokusabela ngenkathi eqhuba ama-electron.

Ukukhiqizwa kwe-aluminium kuncike kakhulu kuma-graphite anode kunqubo yokuncibilikisa i-electrolytic. I-Hall-Inqubo ye-Héroult, ekhiqiza cishe yonke i-aluminium eyinhloko, isebenzisa ama-graphite anode amakhulu akhipha i-oxidize kancane kancane futhi kufanele ashintshwe ngezikhathi ezithile. Lolu hlelo lokusebenza lwezimboni lusebenzisa ubuningi begraphite emhlabeni jikelele.

Amakhemistri ebhethri asafufusa ahlola i-graphite futhi. Amabhethri e-sodium-i-ion kanye namabhethri e-potassium{2}}e-ion angasebenzisa ama-graphite anode, nakuba enezindlela ezihlukene zokuhlanganisa namandla uma kuqhathaniswa namasistimu e-lithium. Njengoba lobu buchwepheshe obuhlukile bebhethri bukhula, bungase budale isidingo esengeziwe sezinto ze-graphite anode.

Abacwaningi bebhethri baphishekela izindlela ezimbalwa zokuthuthukisa ukusebenza kwe-graphite anode ngaphandle kokushiya izinzuzo ezibalulekile zezinto.

Ubunjiniyela be-Interphase bugxile ekuthuthukiseni ukwakheka kwesendlalelo se-SEI. I-SEI inquma i-lithium transport kinetics, cyclability, kanye nezici zokuphepha. Izithasiselo ze-electrolyte ezithuthukisiwe nokwelashwa kwendawo kuhloswe ngayo ukudala izendlalelo ze-SEI ezizacile, ezifanayo kakhulu ezinciphisa ukusetshenziswa kwe-lithium ngesikhathi sokwakheka kuyilapho kukhulisa ukuguquguquka kwe-ionic.

Ubunjiniyela bezinhlayiya buguqula i-graphite morphology ukuze kuthuthukiswe ukusebenza. Abacwaningi baphenya i-graphite yokwenziwa enezimbotshana ezilawulwayo,{1}}izinhlayiya ezilungisiwe ezingaphezulu ezine-electrolyte wetting ethuthukisiwe, kanye nezakhiwo eziyinhlanganisela ezihlanganisa izinhlobo ezahlukene zegraphite ukuze kuthuthukiswe kokubili umthamo kanye nekhono lesilinganiso.

Ukuguqulwa kwesikhala se-interlayer kumele enye indlela. Ngokunweba kancane isikhala phakathi kwezendlalelo ze-graphene-ngokwesibonelo, ngokusebenzisana kwamakhemikhali noma ukukhubazeka kwesakhiwo-abacwaningi bangasheshisa izilinganiso zokusabalalisa i-lithium. Umsebenzi wakamuva ngo-2024 ubonise ukuthi ukunwetshwa kwe-interlayer okulawulwa ngokucophelela kusuka ku-0.3354 nm kuya ku-0.342 nm kuthuthukise kakhulu amandla-okushaja asheshayo kuyilapho kugcinwa ukuzinza kwesakhiwo.

Ubuchwepheshe bokumboza buyaqhubeka nokuthuthuka. Kokubili i-carbon eqinile ne-soft carbon coatings inikeza izinzuzo ezihlukene: izimbobo zekhabhoni eqinile zithuthukisa ukusebenza kwesilinganiso, ikakhulukazi ekuminyaneni okuphezulu kwamanje, kuyilapho ukumbozwa kwekhabhoni ethambile kuthuthukisa ukusebenza kahle kokuqala kwe-coulombic nokuzinza kwamabhayisikili. Ukukhetha izinto zokumboza ezifanele ngokusekelwe kuzimfuneko zohlelo lokusebenza kuvumela ukuthuthukiswa komthamo-wezinga{3}}lonxantathu wempilo ochaza ukusebenza kwebhethri.

Graphite Anode

I-graphite ibhalansisa izidingo eziningi ezinye izinto ezisebenza kanzima ukuze zifane ngesikhathi esisodwa. Isakhiwo sayo esinezingqimba ngokwemvelo sithatha i-lithium ion enoguquko oluncane lwevolumu (ngaphansi kokunwetshwa okungu-10%), okuvumela izinkulungwane zemijikelezo yokushaja. Izinto ezisetshenziswayo zisebenza ngamandla aphansi kakhulu (0.01-0.2 V), okwenza ibhethri libe phezulu. Ichichima, ayibizi kakhulu, futhi iqondwa kahle ngemva kwamashumi eminyaka yokusetshenziswa kwezohwebo. Ngenkathi izinto ezifana ne-silicon zinikeza umthamo ophakeme, zihlushwa izinkinga ezinzima zokwandisa umthamo ezigwenywa yi-graphite.

I-graphite yemvelo ivela emisebenzini yezimayini futhi ngokuvamile inikeza ukuqhutshwa kogesi okungcono ngenxa yokukhanya okuphezulu. Kudinga amandla amancane ukuze kukhiqizwe-cishe u-1.1 × 10⁴ MJ ngethani uma kuqhathaniswa no-4 × 10⁴ MJ ngethani legraphite yokwenziwa. I-graphite yokwenziwa, eyenziwe ngokushisisa i-petroleum coke ibe ngaphezu kuka-2,500 degree, iletha izakhiwo ezingaguquki nobumsulwa. Njengamanje, imboni isebenzisa cishe u-55% wokwenziwa kanye no-45% wegraphite yemvelo, nakuba isabelo semakethe se-graphite yemvelo sikhula ngenxa yezinzuzo zemvelo nezindleko.

Ama-anode e-graphite abhekana nezinselele ngokushaja okusheshayo. Uma ukushaja kwamanje kuphezulu kakhulu, ama-ion e-lithium afika ngokushesha kunalokho angawafaka esakhiweni se-graphite, okuwenza acwebezele njenge-metallic lithium endaweni ye-anode esikhundleni salokho. Le plating ye-lithium yehlisa umthamo futhi ilimaza nebhethri. Abacwaningi bathuthukisa amandla okushaja asheshayo-ngama-surface coatings, i-electrolyte optimization, nobunjiniyela bezinhlayiyana, ngocwaningo lwakamuva lwango-2024 oluzuze amanani okushaja angu-6C (inkokhelo eyimizuzu engu-10) kuyilapho kugcinwa ukuphila komjikelezo okwamukelekayo.

I-silicon ngeke ithathe indawo yegraphite ngokugcwele esikhathini esiseduze, nakuba iba yingxenye yesixazululo. I-Silicon inikeza umthamo ophakeme ka-10x kune-graphite kodwa inweba ngo-300% ngesikhathi sokushaja, okubangela ukuwohloka okusheshayo. Indlela esebenzayo isebenzisa i-silicon-izinhlanganisela ze-graphite, ehlanganisa i-silicon engu-5-15% ibe ama-graphite anode ukuze ithole amandla aphezulu angu-15-20% kuyilapho ilawula izinkinga zokunwetshwa. Ama-silicon anode ahlanzekile asathuthuka, ukuhweba okungenzeka kuncike ekuzuzeni impilo yomjikelezo eyamukelekayo kanye nokwehliswa kwezindleko.

I-graphite anode iyisibonelo sendlela izinto ezibonakala zilula ngokuvamile ezisebenza ngayo ngokunembile ngenxa yalokho kulula. Ama-Lithium ion adinga indawo lapho angaya khona ngesikhathi sokushaja{1}}endaweni ezinzile, ebuyiseleka emuva, futhi engaqhekeki ngemva kwemijikelezo embalwa. Isakhiwo esinengqimba se-graphite sinikeza lokho kanye, ngaphandle kwedrama noma inkimbinkimbi. Ngenkathi abacwaningi bejaha amandla aphezulu kanye nokushaja okusheshayo, bathola ukuthi ukusuka kude kakhulu nezici eziyisisekelo ze-graphite kwethula izinkinga ezivame ukudlula izinzuzo. Ukuqhubeka nokubusa kokubalulekile kumabhethri e-lithium{5}}e-ion cishe kuqhubeka amashumi eminyaka ngaphandle kwemikhawulo yawo, kodwa ngenxa yokuthi leyo mikhawulo iyalawuleka futhi{6}}iqondwa kahle.
