Kwinqanaba lokuqala lemarike yemoto yombane ecocekileyo, iibhetri ze-lithium iron phosphate ion ziibhetri eziqhelekileyo. Nangona kunjalo, ngophuhliso lwebhetri ye-lithium-ion yamandla, ibhetri ye-ion ene-dimensional-dimensional ithathe indawo yebhetri ye-ion ye-lithium. Kuyimfuneko ukuba ibhetri ye-ion ye-lithium ye-phosphate ion xa kuthelekiswa ne-ternary lithium ion ibhetri, ubuninzi bamandla buphantsi.

Kwibhetri yokuqala ye-lithium-ion, ubuninzi bamandla ebhetri ye-lithium iron phosphate ion yi-100Wh/kg kuphela, kunye noxinano lwamandla ebhetri ye-ternary lithium ion inokufikelela kwi-140Wh / kg nangaphezulu. Ngokuvuswa kwenkxaso-mali encinci yemoto yombane, kunye nexabiso eliphezulu lezithuthi zombane ezicocekileyo, i-gap icacile kunemizekelo yamafutha endabuko. Ubuninzi bamandla obuphantsi buphantsi, kwaye i-lithium iron phosphate ion ibhetri imfutshane kubomi bebhetri ayinanzuzo.

Ukongeza, ukusebenza okuchasene nobushushu obuphantsi kwebhetri ye-ion ye-lithium ye-phosphate ion kunye nokusebenza kokutshaja kuthelekiswa nebhetri ye-lithium ion ye-ternary. Ngaphantsi kweemeko ezibandayo zasebusika, ukuthotywa kweebhetri ze-ion ze-lithium kuya kufikelela ngaphezu kwe-50%, kunye nokusebenza kancinci kokutshaja, okuya kunciphisa kakhulu ukusebenza kakuhle kokupasa. Ke ngoko, uxinaniso lwamandla lungcono, kwaye ibhetri ye-lithium-ion ye-yuan ezintathu eyomeleleyo ifunwa ngokuthe ngcembe lishishini lesithuthi.

Ngophuhliso lwemarike, kukho imifuziselo ngakumbi nangakumbi ubomi bebhetri NEDC ngaphezu 600km. Nangona kunjalo, ibhetri ye-lithium-ion ene-dimensional emithathu ayibi. Nangona kukho inzuzo kubuninzi bamandla kunye nokusebenza kokutshaja, iphantsi kune-lithium iron phosphate ion ibhetri kubomi bomjikelezo webhetri kunye nobomi bomjikelezo webhetri.

Ibhetri ye-lithium-ion ye-ternary isetyenziswe ngokuqinileyo yi-electrode efanelekileyo, i-ternary positive material ye-lithium nickel-watery oxynumide okanye i-nickel-cobalt-aluminate, inqwenelekayo ukuba isekelwe kwi-nickel ityuwa, ityuwa ye-cobalt, kunye neetyuwa ze-manganese. Into ye-cobalt kwezi zinto zimbini zilungileyo ze-electrode zezesinyithi ezixabisekileyo. Ngokutsho kwedatha yewebhusayithi echaphazelekayo, amaxabiso ereferensi yensimbi ye-cobalt yasekhaya yi-277,500 yuan / ton, kunye nokunciphisa izinto eziphathekayo, ixabiso lisakhula.

Okwangoku, iindleko zebhetri ye-lithium-ion ezintathu-dimensional yi-0.85-1 yuan / WH; iindleko ze-lithium iron phosphate ion ibhetri ngaphandle kwezinto ezihloniphekileyo zentsimbi yi-0.58-0 kuphela.

6 yuan / WH. Ukongezelela, ubomi bomjikelezo webhetri ye-lithium ion ye-lithium-dimensional ifana nebhetri ye-lithium yensimbi, kwaye inani lentlawulo kunye nokukhutshwa kwebhetri ye-phosphate ion ngamaxesha angama-2,000. Ngokubanzi kusetyenziso lweminyaka emi-4, uninzi lwentsebenzo yebhetri iya kuthomalalisa, nto leyo ekhokelela kwixabiso eliphezulu lokutshintsha ibhetri.

Kukhuseleko lwebhetri, ukunyuswa kwe-thermal ye-cell cell cell ye-ion-dimensional ion iphantsi, kwaye ifikelele kuluhlu lwee-degrees ze-200, kwaye le thermal ngaphandle kolawulo iya kukhuseleka. Isezantsi isezantsi. Ngoxinano lwamandla ebhetri ye-ternary lithium-ion, iingozi zokhuseleko zifutshane.

Enyanisweni, sihlala sibona izithuthi zombane ezicocekileyo iindaba ezizenzekelayo. Ke ngoko, ukhuseleko lwebhetri sesona sigulo siphambili kwiimodeli zeemoto zombane. Kutheni kufuneka usebenzise ibhetri ye-lithium-ion enemigangatho emithathu? Umphambili wahlula izinto ezilungileyo kunye nokungalunganga kwebhetri ye-ion ye-lithium yesinyithi kunye nebhetri ye-ion ene-dimensional ion.

Abanye abantu banokubuza. Ekubeni ukhuseleko lwebhetri ye-ion ye-lithium ye-iron phosphate ilungile, ubomi bomjikelo webhetri busebude, kwaye iindleko zisephantsi, ngoko kutheni abavelisi abaninzi basagxininisa kwinqanaba lokungena kwiimoto zombane ezicocekileyo zokuthwala ibhetri ye-ternary lithium-ion? Ngokwenyani, ibhetri ye-ion ye-lithium ye-phosphate ion ixhotyiswe kwinqanaba lokungena kwimoto yombane esulungekileyo ngokwenene ngumbono ofanelekileyo. Nangona kunjalo, ubuninzi bamandla obukhoyo bebhetri ye-lithium ye-iron phosphate ion buphantsi, kwaye i-NEDC ye-mileage engapheliyo yeemodeli zolu hlobo lwebhetri ngokusisiseko ijikeleze i-200km, kwaye akukho nkxaso-mali yesizwe.

Ukuba ipakethe yebhetri kufuneka ifikelelwe, inani leebhetri kufuneka longezwe, elikhokelela ekukhuleni okutsha kwesithuthi. Kwaye ubungakanani bomgangatho wokungena jikelele awukho mkhulu, ngoko ke iipakethi ezininzi zebhetri azinakubekwa. Ngoko ke, ibhetri ye-ion ye-phosphate yangoku ikhethwa ngokubanzi ngebhasi yombane, ikhadi lokukhanya kombane kunye nezinye iindlela zokuthutha, kwaye banendawo eninzi yebhetri, kwaye ngenxa yendlela ehleliweyo, akufuneki baqwalasele ubomi bebhetri.

Ngokubhekiselele kukhuseleko kwibhetri, abantu akufuneki bakhathazeke kakhulu. Okwangoku, inkqubo yoxinzelelo oluphezulu lwebhetri ye-lithium-ion enemilinganiselo emithathu kunye neendawo ezinoxinzelelo oluphezulu zifikeleleke kwinqanaba eliphezulu le-IP67 labantu abangenamanzi kunye nothuli, nakwimitha ye-1 enzulu yamanzi efakwe kwi-30 imizuzu yebhetri ngaphandle komonakalo. Ngaphezu koko, xa ibhetri imfutshane, i-high-voltage overload, kunye nokungqubana, inkqubo iya kuqhawula ngokuzenzekelayo amandla ombane aphezulu, kunye nomngcipheko wokuzitshisa.

Ngaphaya koko, ukusebenza okuphezulu kokutshaja kwebhetri ye-lithium ion enemigangatho emithathu kunokuxhasa ukutshaja kwezinga elikhulu, kuphucule ngakumbi ukusebenza kakuhle kokutshaja, kwaye amava aya kuba ngcono. Ukongezelela, ukuze kuphuculwe ukukhuphisana, iinkampani ezininzi zeemoto ziye zaqalisa umgaqo-nkqubo wokugcina amandla kunye nokuthenga kwakhona ukunciphisa ingxaki yeendleko zebhetri.
