I-01 - i-lithium iron phosphate ibonisa ukunyuka okunyukayo

Ibhetri yeLithium ineenzuzo zobukhulu obuncinci, ubunzima obulula, ukutshaja ngokukhawuleza kunye nokuqina. Inokubonwa kwibhetri yeselula kunye nebhetri yemoto. Phakathi kwazo, ibhetri ye-lithium iron phosphate kunye nebhetri ye-ternary ingamasebe amabini amakhulu ebhetri ye-lithium ngoku.

Kwiimfuno zokhuseleko, kwintsimi yeemoto zabahambi kunye neenqwelo ezikhethekileyo, ibhetri yamandla e-lithium iron phosphate enexabiso eliphantsi, iteknoloji yemveliso ekhulileyo kunye nekhuselekileyo isetyenziswe kwizinga eliphezulu. Ibhetri ye-lithium ye-ternary enamandla athile aphezulu isetyenziswa ngokubanzi kwibala leemoto zabakhweli. Kwiqela elitsha lezaziso, umlinganiselo weebhetri ze-lithium iron phosphate kwintsimi yezithuthi zabakhweli uye wanda ukusuka ngaphantsi kwe-20% ngaphambi kokuba malunga ne-30%.

I-Lithium iron phosphate (LiFePO4) yenye yezinto ezisetyenziswa ngokuqhelekileyo zecathode kwiibhetri ze-lithium-ion. Inozinzo oluhle lwe-thermal, ukufunxa okuncinci kokufuma kunye nokusebenza komjikelo obalaseleyo wokukhupha intlawulo phantsi kwemeko ehlawulwe ngokupheleleyo. Yingqwalasela yophando, ukuveliswa kunye nophuhliso kwintsimi yamandla kunye nokugcinwa kwamandla iibhetri ze-lithium-ion. Nangona kunjalo, ngenxa yokuncitshiswa kwesakhiwo sayo, ibhetri ye-lithium-ion kunye ne-lithium iron phosphate njengoko izinto eziphathekayo zinokuqhuba kakubi, isantya sokuhamba kancinci kwe-lithium ion, kunye nokusebenza kakubi kokukhutshwa kwiqondo lokushisa eliphantsi. Oku kubangela i-mileage ephantsi yezithuthi zokuqala ezixhotyiswe ngebhetri ye-lithium iron phosphate, ngakumbi kwimeko yobushushu obuphantsi.

Ukuze kufuneke ukuphumelela mileage yonyamezelo, ngakumbi emva komgaqo-nkqubo wenkxaso-mali yezithuthi zamandla amatsha ubeke phambili iimfuno eziphezulu zokunyamezela isithuthi, ubuninzi bamandla, ukusetyenziswa kwamandla kunye neminye imiba, nangona ibhetri ye-lithium iron phosphate ikwimarike ngaphambili, i-ternary lithium. ibhetri enoxinano lwamandla aphezulu ngokuthe ngcembe ibe yeyona nto iphambili kwimarike yemoto yabahambi yamandla. Inokubonwa kwisibhengezo samva nje ukuba nangona ubungakanani bebhetri ye-lithium yentsimbi ye-phosphate kwindawo yezithuthi zabakhweli buphinde babuyela, ubungakanani bebhetri ye-lithium ternary isemalunga ne-70%.

I-02 - ukhuseleko lolona luncedo lukhulu

I-nickel cobalt aluminium okanye i-nickel cobalt manganese isetyenziswa ngokubanzi njengezinto ze-anode ze-ternary lithium iibhetri, kodwa umsebenzi ophezulu wezinto eziphathekayo awuzisi nje amandla aphezulu, kodwa uzisa nemingcipheko yokhuseleko oluphezulu. Izibalo ezingaphelelanga zibonisa ukuba ngo-2019, inani leengozi zokuzitshisa kwezithuthi zamandla amatsha lakhankanywa izihlandlo ezili-14 ngaphezulu kunolo ngo-2018, kwaye iibrendi ezinje ngoTesla, Weilai, BAIC kunye ne-Weima ziye zavela ngokulandelelana kwiingozi zokuzitshisa.

Ingabonwa kwingozi yokuba umlilo uvela ngokukodwa kwinkqubo yokutshaja, okanye emva nje kokutshaja, kuba ibhetri iya kunyuka kwiqondo lokushisa ngexesha lokusebenza kwexesha elide. Xa ubushushu bebhetri ye-lithium ye-ternary ingaphezulu kwe-200 ° C, izinto ezintle zilula ukubola, kwaye ukusabela kwe-oxidation kukhokelela ekubalekeni ngokukhawuleza kwe-thermal kunye nokutsha okunobundlobongela. Isakhiwo se-olivine se-lithium iron phosphate izisa ukuzinza kobushushu obuphezulu, kwaye iqondo lokushisa elibalekayo lifikelela kuma-800 ° C, kunye nokuveliswa kwegesi encinci, ngoko kukhuselekile. Yiyo loo nto, ngokusekwe kwiingqwalasela zokhuseleko, iibhasi zamandla amatsha ngokubanzi zisebenzisa iibhetri ze-lithium iron phosphate, ngelixa iibhasi zamandla amatsha ezisebenzisa iibhetri ze-ternary lithium azikwazi okwethutyana ukungena kwikhathalogu yezithuthi zamandla amatsha ukuze ziphakanyiswe kwaye zisetyenziswe.

Kungekudala, iimoto ezimbini zombane ze-Changan Auchan ziye zamkela ibhetri ye-lithium yensimbi ye-phosphate, eyahlukileyo kwiinkampani zezithuthi eziqhelekileyo ezijolise kwiimoto. Iimodeli ezimbini zeChangan Auchan ziiSUV kunye neMPV. UXionng zewei, usekela-manejala jikelele weChang’an Auchan Research Institute, uxelele intatheli oku: “Oku kubonisa ukuba iAuchan ingene ngokusemthethweni kwixesha lamandla ombane emva kweminyaka emibini yemigudu.”

Ngokuphathelele kutheni i-lithium iron phosphate ibhetri isetyenzisiweyo, i-Xioning yathi ukhuseleko lwezithuthi zamandla amatsha luye lwahlala "lweentlungu" zabasebenzisi, kunye neyona nto ichaphazelekayo ngamashishini. Ukuqwalasela oku, ipakethe yebhetri ye-lithium yentsimbi ye-phosphate ethwalwa yimoto entsha ilugqibile uvavanyo lomda olungaphezulu kwe-1300 ° C yokubhaka idangatye, - 20 ° C ukuma kobushushu obuphantsi, i-3.5% yesisombululo setyuwa, impembelelo ye-11 kn yangaphandle yoxinzelelo, njl. ., kwaye iphumelele "ezine zingoyiki" isisombululo sokhuseleko lwebhetri "engoyiki ubushushu, ungoyiki ukubanda, ungoyiki amanzi, ungoyiki impembelelo".

Ngokweengxelo, i-Changan Auchan x7ev ixhotyiswe ngemagnethi esisigxina ye-synchronous motor enamandla amakhulu e-150KW, kunye ne-mileage yokunyamezela engaphezulu kwe-405 km kunye nebhetri yobomi obude kakhulu ngamaxesha angama-3000 wokutshaja kwebhayisikile. Kwiqondo lobushushu eliqhelekileyo, kuthatha isiqingatha seyure kuphela ukongeza kwimayile yokunyamezela engaphezulu kwe-300 km. "Enyanisweni, ngenxa yobukho benkqubo yokubuyisela amandla e-braking, ukunyamezela kwesithuthi kunokufikelela malunga ne-420 km phantsi kweemeko zokusebenza zasedolophini." Xiong wongeza.

Ngokwesicwangciso esitsha sophuhliso loshishino lwezithuthi zamandla (2021-2035) (Idrafti yeenkcazo) ekhutshwe nguMphathiswa wezoShishino kunye nobuchwepheshe bolwazi, ukuthengiswa kwezithuthi zamandla amatsha kuya kuba malunga ne-25% ngo-2025. Kuyabonakala ukuba umlinganiselo izithuthi zamandla amatsha ziya kuqhubeka ukwanda kwixesha elizayo. Kulo mxholo, kubandakanywa iChang'an Automobile, amashishini azimeleyo ezithuthi zohlobo oluzimeleyo akhawulezisa uyilo lwentengiso yezithuthi zamandla amatsha.
