Mabatire a lithiamu iron phosphate adalamulira msika kwa nthawi yoyamba m'zaka zinayi

Mu 2021, kukula kwa batire ya lithiamu iron phosphate kudaposa batire ya ternary lithium yomwe yatenga mwayi wamsika kwazaka zambiri.Malinga ndi zomwe zili pamwambapa, mphamvu yoyika ya lithiamu iron phosphate ndi mabatire a ternary lithiamu pamsika wa batri yamagetsi mu 2021 idzawerengera 53% ndi 47% motsatana, ndikusinthiratu zomwe zikuchitika kuti kutulutsa kwa mabatire a lithiamu iron phosphate kwachepa. kuposa mabatire a ternary lithium kuyambira 2018.

Chen Yongchong, pulofesa ku Institute of Electrical Engineering of the Chinese Academy of Sciences, adauza atolankhani kuti, "Kukula kwamphamvu kwa mabatire a lithiamu iron phosphate kumabwera chifukwa chakukula kwachangu kwamakampani opanga magalimoto aku China.Ngakhale zotsatira za COVID-19 mchaka chatha zikadalipobe, zomwe zikuchitika mwachangu pamakampani opanga magalimoto aku China sizinasinthe pakupanga msika komanso kugulitsa.Panthawi imodzimodziyo, ponena za zolinga za carbon peak ndi carbon, magalimoto atsopano amphamvu alandira chidwi kwambiri. "

Ziwerengero zaposachedwa kwambiri za China Association of Automobile Manufacturers: Mu 2021, kuchuluka kwa magalimoto a New energy ku China ndi mayunitsi 3.545 miliyoni, ndikukula kwa chaka ndi chaka mpaka 159.5%, ndipo gawo lamsika lakwera mpaka 13.4% .

Ndikoyenera kudziwa kuti kuchuluka kwa katundu wa lifiyamu chitsulo mankwala batire kamodzi "kuposa" kukula kwa kukula kwa magalimoto atsopano amphamvu, omwe amagwirizana mwachindunji ndi kuchepa kwapang'onopang'ono kwa ndalama zothandizira magalimoto atsopano ku China.Zothandizira zatsopano zamagalimoto aku China zikuyembekezeka kuchotsedwa mu 2023, ndipo mwayi wa mabatire a ternary lithiamu kuti apeze ndalama zothandizira ndalama chifukwa chakuchulukira kwawo kwamphamvu kudzachepa.Kuphatikizidwa ndi kukwera kwa msika kwa mabatire a lithiamu iron phosphate pagawo losungira mphamvu zamagetsi muzaka zingapo zikubwerazi, kukula kwa mabatire a lithiamu iron phosphate kudzaposa mabatire a ternary lithium.

Kuchita kwazinthu komanso phindu lamtengo wapatali

Kuphatikiza pa malo abwino akunja, mphamvu yamankhwala a lithiamu iron phosphate batire ikupitanso patsogolo.Kuchita kwaposachedwa kwazinthu komanso ubwino wamtengo wapatali wa mabatire a lithiamu iron phosphate wakhala wopambana, chomwe chiri chofunikira kwambiri pa "kubwerera" kwake mu 2021.

Kuyambira 2020, byd anapezerapo kuyambira tsamba lithiamu chitsulo mankwala mabatire, lifiyamu batire mphamvu kachulukidwe zosakwana yuan atatu wafooketsa kuipa chikhalidwe cha luso lopitirira luso pa nthawi yomweyo kupanga lithiamu chitsulo mankwala mabatire akhoza kukwaniritsa kufunika kwa onse m'munsimu osiyanasiyana Zitsanzo za 600 km, makamaka makampani opanga magalimoto amphamvu monga byd, tesla ku lithiamu iron phosphate batire kukula kwabweretsa mphamvu zamphamvu.

Poyerekeza ndi ternary mabatire lifiyamu ndi mitengo mkulu ndi zitsulo ndi osowa monga cobalt ndi faifi tambala, mtengo wa lithiamu chitsulo mankwala batire ndi wotsika, makamaka pamene mtengo wa zipangizo monga lithiamu anode, cathode ndi electrolyte kuwuka, mtengo kuthamanga lalikulu. -Kupanga kwakukulu kumakhala kochepa.

Mu 2021, mitengo ya lithiamu carbonate ndi cobalt, zida zopangira mabatire a lithiamu, zidzakwera.Ngakhale pamsika wapadziko lonse lapansi komwe mabatire a lithiamu a terpolymer adatenga mwayi waukulu, Tesla, BMW, Ford, Hyundai, Renault ndi makampani ena amagalimoto anena kuti aganiza zosinthira mabatire a lithiamu chitsulo cha phosphate ndi zabwino zotsika mtengo.

Ndikoyenera kudziwa kuti mwayi wa ngozi wa mabatire a ternary lithiamu akadali apamwamba kwambiri kuposa mabatire a lithiamu chitsulo mankwala, chifukwa chachikulu ndikuti mapangidwe amkati amtunduwu ndi otetezeka.
