Esigabeni sokuqala semakethe yezimoto zikagesi, amabhethri e-lithium iron phosphate ion angamabhethri ajwayelekile. Kodwa-ke, ngokuthuthukiswa kwebhethri ye-lithium-ion yamandla, ibhethri ye-ion enezinhlangothi ezintathu kancane kancane yashintsha ibhethri ye-ion ion ye-lithium. Kudingeka ibhethri ye-ion ye-lithium iron phosphate uma kuqhathaniswa nebhethri ye-lithium ion ye-ternary, ukuminyana kwamandla kuphansi.

Ebhethrini lokuqala eliguqukayo le-lithium-ion, ukuminyana kwamandla ephakethe lebhethri le-lithium iron phosphate ion kungu-100Wh/kg kuphela, futhi ukuminyana kwamandla ephakethe lebhethri le-ternary lithium ion kungafinyelela ku-140Wh/kg noma ngaphezulu. Ngokuvuswa kwesibonelelo esincane semoto kagesi, kanye nentengo ephezulu yezimoto ezihlanzekile zikagesi, igebe lisobala kunezinhlobo zendabuko zikaphethiloli. Ukuminyana kwamandla okuphansi kuphansi, futhi ibhethri le-ion ye-lithium iron phosphate lifushane empilweni yebhethri alinanzuzo.

Ngaphezu kwalokho, ukusebenza okuphambene nokushisa okuphansi kwebhethri ye-ion ye-lithium iron phosphate ion nokusebenza kokushaja kuqhathaniswa nalokhu kwebhethri ye-lithium ion ye-ternary. Ngaphansi kwezimo ezibandayo zasebusika, ukuncishiswa kwamabhethri e-lithium iron ion kuzofinyelela ngaphezu kuka-50%, kuhlanganiswe nokusebenza kancane kokushaja, okuzonciphisa kakhulu ukusebenza kahle kokudlula. Ngakho-ke, ukuminyana kwamandla kungcono, futhi ibhethri ye-lithium-ion yama-yuan amathathu eqinile kancane kancane ifunwa yinkampani yezimoto.

Ngokuthuthuka kwemakethe, kuyanda amamodeli empilo yebhethri ye-NEDC engaphezu kuka-600km. Kodwa-ke, ibhethri ye-lithium-ion enezinhlangothi ezintathu ayibi kabi. Yize kunenzuzo ekuminyana kwamandla nokusebenza kokushaja, iphansi kunebhethri le-ion ye-lithium iron phosphate empilweni yomjikelezo webhethri nempilo yomjikelezo webhethri.

Ibhethri ye-lithium-ion ye-ternary isetshenziswa ngokuqinile yi-electrode ephozithivu, i-ternary positive material ye-lithium nickel-watery oxynumide noma i-nickel-cobalt-aluminate, iyadingeka ukuthi isekelwe kusawoti we-nickel, usawoti we-cobalt, nosawoti we-manganese. Isici se-cobalt kulezi zinto ezimbili ezinhle ze-electrode ingeyensimbi eyigugu. Ngokusho kwedatha yewebhusayithi efanele, amanani ereferensi yensimbi ye-cobalt yasekhaya angama-277,500 yuan / ton, futhi ngokuncipha kwezinto zokwakha, intengo isakhula.

Njengamanje, izindleko zebhethri ye-lithium-ion enezinhlangothi ezintathu yi-0.85-1 yuan / WH; Izindleko zebhethri ye-ion ye-lithium iron phosphate ngaphandle kwezakhi zensimbi ezihloniphekile yi-0.58-0 kuphela.

6 yuan / WH. Ukwengeza, impilo yomjikelezo webhethri ye-lithium ion enezinhlangothi ezintathu nayo ifana nebhethri ye-lithium iron-ion, futhi inani lokushaja nokukhishwa kwebhethri ye-phosphate ion izikhathi ezingu-2,000. Ngokujwayelekile lapho kusetshenziswa iminyaka emi-4, ukusebenza kwebhethri okuningi kuzoncipha, okuphinde kuholele ezindlekweni eziphezulu zokushintsha ibhethri.

Ekuphepheni kwebhethri, ukusheshisa okushisayo kweseli yebhethri ye-ion enezinhlangothi ezintathu kuphansi, futhi isifinyelele ibanga elingamadigri angu-200, futhi lokhu kushisa okushisayo kuzophepha. Okuphansi kungaphansi. Ngokuminyana kwamandla webhethri le-ternary lithium-ion, ubungozi bokuphepha bufushane.

Eqinisweni, singakwazi ukubona izimoto zikagesi ezihlanzekile izindaba ezizenzakalelayo. Ngakho-ke, ukuphepha kwebhethri nakho kuyisifo esikhulu kumamodeli ezimoto zikagesi. Kungani kufanele usebenzise ibhethri ye-lithium-ion enezinhlangothi ezintathu? Ingaphambili lihlukanise okuhle nokubi kwebhethri ye-ion ye-lithium iron phosphate kanye nebhethri ye-ion enezinhlangothi ezintathu.

Abanye abantu bangase babuze. Njengoba ukuphepha kwebhethri ye-ion ye-lithium iron phosphate kuhle kakhulu, impilo yomjikelezo webhethri iseyinde, futhi izindleko zisencane, ngakho-ke Kungani abakhiqizi abaningi besaphikelela ezingeni lokungena kwezimoto zikagesi ezihlanzekile ukuze baphathe ibhethri ye-ternary lithium-ion? Ngempela, ibhethri ye-ion ye-lithium iron phosphate efakwe ezingeni lokungena imoto kagesi ehlanzekile ingumbono ofaneleka kakhulu. Kodwa-ke, ukuminyana kwamandla kwamanje kwebhethri ye-ion ye-lithium iron phosphate iphansi, futhi i-NEDC yebanga elingapheli lamamodeli amamodeli alolu hlobo lwebhethri ngokuyisisekelo lizungeze u-200km, futhi alukho uxhaso lukazwelonke.

Uma iphakethe lebhethri lizofinyelelwa, inombolo yamaphakethe ebhethri kufanele yengezwe, okuholela ekukhuleni okusha kwemoto. Futhi usayizi wemodeli yezinga lokungena elijwayelekile awumkhulu, ngakho-ke amaphakethe amaningi ebhethri awakwazi ukubekwa. Ngakho-ke, ibhethri lamanje le-ion ye-phosphate ngokuvamile likhethwa ibhasi likagesi, ikhadi lokukhanya kukagesi nezinye izinto zokuhamba, futhi banendawo eyengeziwe yebhethri, futhi ngenxa yomzila omisiwe, akudingeki bacabangele impilo yebhethri.

Mayelana nokuphepha ebhethrini, abantu akudingeki bakhathazeke kakhulu. Okwamanje, isistimu yomfutho ophezulu webhethri ye-lithium-ion enezinhlangothi ezintathu kanye nezingxenye zokucindezela okuphezulu ngokuyisisekelo zifinyelelwa ezingeni eliphezulu kakhulu le-IP67 izakhamuzi ezingangeni manzi nezingangenwa uthuli, ngisho nasemanzini ayimitha elingu-1 acwiliswe imizuzu engu-30 ibhethri ngaphandle kokulimala. Ngaphezu kwalokho, uma ibhethri lilifushane, ligcwele amandla kagesi aphezulu, futhi lishayisana, uhlelo luzonqamula ngokuzenzakalelayo ukunikezwa kwamandla kagesi aphezulu, kanye nengozi yokuzishisa.

Ngaphezu kwalokho, ukusebenza kokushaja okuphezulu kwebhethri ye-lithium ion enezinhlangothi ezintathu kungasekela ukushajwa kwenani elikhulu, kuthuthukise ukusebenza kahle kokushaja, futhi ukuzizwisa kuzoba ngcono. Ngaphezu kwalokho, ukuze kuthuthukiswe ukuncintisana, izinkampani eziningi zezimoto ziye zasungula inqubomgomo yokonga amandla kanye nokuthenga kabusha ukuze kuncishiswe inkinga yezindleko zebhethri.
