Noma kunjalo, ama-recyclers akhethekile afana ne-Li-Cycle kanye ne-Redwood Materials manje aphatha womabili amafomethi, ashaja amaphrimiyamu angu-$0.50-0.80 ngekhilogremu ngayinye yesikhwama uma kuqhathaniswa no-$0.30-0.50 ngekhilogremu yamaseli e-prismatic.

Ukuqapha ukuphepha kufanele kubhekane nefomethi{0}}yezindlela zokuhluleka ezithile. Amasistimu e-Prismatic adinga izinzwa zokucindezela ezithola ukunqwabelana kwegesi yangaphakathi{2}}izixwayiso ngokuvamile zisebenza ku-0.2 MPa, ngaphambi kokuthi kuvele izimo eziyingozi. Amasistimu ezikhwama ayazuza kuzinqubo zokuhlola okubukwayo: izisebenzi zokunakekela eziqeqeshelwe ukubona ukukhuphuka kogqinsi ngo-5mm zinganqanda ukwehluleka okungu-80% kwenkambu ngokushintshwa okusebenzayo. Ama-OEM ezimoto manje acacisa amasistimu okubona azenzakalelayo okuhlolwa kwephakethe lebhethri, athola ukuvuvukala kwesikhwama okungabonakali okungabonakali kubantu ababukele.

Ukuthola ikhwalithi kuhlukanisa ukuthunyelwa okuphumelelayo kweziyinkinga. Isigaba-Abakhiqizi beseli elingu-1-i-CATL, i-LG Energy Solution, i-Samsung SDI, i-BYD-bagcina ukulawulwa kwekhwalithi okuqinile namazinga okukhubazeka angaphansi kwezingxenye ezingu-50 ngesigidi. Abahlinzeki besibili bangase behlise intengo ngo-20-30% kodwa babonise izilinganiso zokuhluleka izikhathi ezingu-10-100 ngaphezulu. Umkhiqizi wemishini yezimboni ye-B2B ushintshele kubahlinzeki bezikhwama ababiza kancane ukuze behlise izindleko zebhethri ngo-$15 iyunithi ngayinye, kuphela ukuze bathole ukwehluleka okungu-4% kuzilinganiso zokuhluleka kwewaranti okukhiqiza u-$200,000 ezindlekweni zokushintshwa kanye nokulimala kwesithunzi. Ukubuyela kubahlinzeki be-premium kubuyisele ukwethembeka ngamaphrimiyamu ezindleko ezamukelekayo.

Womabili amafomethi asebenzisa i-lithium-ikhemikhali ye-ion enokusabela okubuyiselekayo kwe-electrochemical. Ngesikhathi sokukhishwa, ama-ion e-lithium asuka ku-anode (ngokuvamile i-graphite) esebenzisa i-electrolyte ewuketshezi aye ku-cathode (ama-oxide ensimbi ahlukahlukene). Ukusebenzisa amandla kagesi angaphandle kubuyisela emuva lokhu kugeleza, kubuyisela amandla amakhemikhali. Ngokungafani namabhethri e-lithium ayinhloko asebenzisa i-lithium metal anode emsulwa engakwazi ukuhlehla ngokuphephile, i-lithium{4}}amaseli e-ion ahlanganisa i-lithium ibe okokubamba okuzinzile{5}}ukuvumela imijikelezo yokushajwa engu-500-5,000 kuye chemistry nezimo zokusebenza.

Ukushintsha okuqondile akuvamile ukusebenza ngenxa yokungahambelani kobukhulu nogesi. Ngisho noma ubukhulu bomzimba bufana, amaseli e-prismatic nawesikhwama abonisa amajika kagesi ahlukene, ukumelana kwangaphakathi, kanye nezidingo zemishini. Amasistimu okuphatha amabhethri alinganiselwe kufomethi eyodwa angase angayiphathi kahle enye, abeke engcupheni ukushajwa ngokweqile,{2}}ukuphuma ngokweqile, noma imicimbi eshisayo. Ukuguqulwa kwefomethi okuphumelelayo kudinga ukuklama kabusha kwephekhi okuphelele okuhlanganisa ukulungiswa kabusha kwe-BMS, ukuguqulwa kwendawo ebiyelwe ngomshini, nokuhlola okubanzi kokuqinisekisa.

Ngaphansi kwezimo zokusebenza ezifanayo, amaseli e-prismatic avamise ukuletha imijikelezo engu-25-40% yomjikelezo omude-3,000-4,000 imijikelezo uma iqhathaniswa nengu-2,000-3,000 kwezinye izikhwama. Le nzuzo isukela ekuphathweni okushisayo okuphakeme nokuvikelwa komshini okuvimbela ukunqwabelana komonakalo wangaphakathi. Kodwa-ke, idizayini efanele yokushisa kanye nemishini ingaletha ubude besikhathi sokuphila kwamaseli esikhwama phakathi kuka-10-15% wezinto ezilingana ne-prismatic. Ubude bokuphila bomhlaba wangempela buncike kakhulu ezimeni zokusebenza (izinga lokushisa, umthetho olandelwayo wokushaja, ukujula kokukhipha) kunefomethi yodwa.

Amaphrofayili okuphepha ayahluka esikhundleni sokukleliswa ngokwezigaba. Amaseli e-Prismatic aqukethe ukwehluleka ngaphakathi kwezindlu eziqinile kodwa adala ukucindezela kwangaphakathi okuphezulu phakathi nemicimbi eshisayo{1}}engase ibangele ukuphuma komoya okunobudlova. Amaseli ezikhwama ahluleka kancane kancane ngokuvuvuka kancane kancane, anikeze isixwayiso esibonakalayo, kodwa ukupakishwa kwawo okuguquguqukayo akunikezeli ukuvikelwa kokubhoboza kwangaphakathi. Amasistimu aklanywe kahle azuza ukuphepha okufanayo kungakhathaliseki ifomethi ngokuphathwa okushisayo okufanele, idizayini yemishini, nokuvikela isistimu yokuphatha ibhethri.

Okubalulekile kuhlelo lokusebenza shayela ukukhetha kwefomethi. Ama-Smartphones athuthukisa ubukhulu obuncane kanye nesisindo endaweni engalungile-amaseli ezikhwama ayahamba phambili kulezi zindlela. Izimoto zikagesi zibeka phambili impilo yomjikelezo, ukuzinza kwe-thermal, nokuqina komshini kunokonga isisindo esimaphakathi{3}}amaseli e-prismatic asebenzela lezi zidingo kangcono. Nokho, okuhlukile kukhona: ama-EV athile (okuhlukile kwe-Nissan Leaf) asebenzisa ngempumelelo amaseli ezikhwama, kuyilapho ama-smartphones aqinile angase acacise amaseli amancane e-prismatic ukuze aqine ukuqina.

Ukukhethwa kwefomethi kunomthelela ku-15-30% wesamba sezindleko zesistimu yebhethri ngaphezu kwezindleko zeseli eluhlaza. Amaseli ePrismatic abiza u-15-20% ngaphezulu nge-kilowatt-hora kodwa adinga izakhiwo ezilula zokusekela. Amaseli ezikhwama onga ezindlekweni zamaseli kodwa afuna amasistimu okucindezela asezingeni eliphezulu kanye nokuphathwa kokushisa. Ezingeni lesistimu, umehluko wezindleko uyancipha ube ngu-5-15% kuye ngevolumu yokukhiqiza kanye nezidingo zokushisa. Imithelela yokusebenza nokuthembeka kuvame ukudlula ukucatshangelwa kwezindleko eziqondile ekukhetheni ifomethi.

Amaseli e-Prismatic nama-pouch amelela izindlela zokupakisha ezihlukilekwe-lithium-ikhemikhali ye-ion-amagobolondo angunxande aqinile ngokumelene nama-laminates aguquguqukayo{2}}ngalinye lithuthukisa amapharamitha okusebenza ahlukene kunokumela ubuchwepheshe obuphakeme/obuphansi

Ukuminyana kwamandla kuthanda imiklamo yezikhwama(174 Wh/kg) ngaphezu kwezindlela ezihlukile ze-prismatic (157-165 Wh/kg), okuhumushela ku-10-15% ukonga isisindo okubalulekile kuma-electronics aphathekayo nezinhlelo zokusebenza ze-aerospace

Izinzuzo zokuphatha okushisayo zingezafomethi ye-prismaticngokusebenzisa ukushiswa kokushisa kwegobolondo lensimbi, ukunika amandla{0}ukukhishwa kwamandla aphezulu okuqhubekayo kuzinhlelo zokusebenza zezimoto nezimboni lapho ama-pouch cell adinga izakhiwo zokupholisa eziyinkimbinkimbi.

Izakhiwo zezindleko ziyehluka ngokwesu: ama-pouch cell aletha izindleko zokukhiqiza eziphansi ngo-15-20% kodwa afuna uhlelo olukhulu{2}}lezinga lokutshala imali ekusekelweni kwemishini kanye nezindleko zesistimu yokuphatha okushisayo zihlangana phakathi kuka-5-15% esikalini

Izidingo zohlelo lokusebenza zithuthukisa ukukhetha kwefomethi elungilekuzo zonke izilinganiso zezinqumo eziyisithupha: iphrofayela yamandla, indawo yokusebenza, imikhawulo yesikhala, umthamo wokukhiqiza, izidingo zempilo yomjikelezo, nemithetho yokuphepha-ayikho ifomethi "engcono kakhulu" ekhona kuzo zonke izimo zokusetshenziswa.
