Ukukhokela ugqatso lobushushu obuphantsi, i-XDLE -20 ukuya -35 Celsius iibhetri ze-lithium eziphantsi kobushushu zifakwa kwimveliso yobuninzi.

Indlela yokoyisa ubushushu obuphantsi bebhetri ye-lithium ?

"Phantsi kweemeko zobushushu obuphantsi, izinga lokusabela kweekhemikhali ngaphakathi kwebhetri liyancipha kwaye isantya sokuhamba kwee-ion kwi-electrolyte siyehla, nto leyo echaphazela amandla ombane.ibhetri ye-lithiumukuhlawula kunye nokukhupha ukusebenza kakuhle. Ukongeza, amaqondo obushushu aphantsi anokubangela utshintsho kulwakhiwo lwesixhobo ngaphakathi kwebhetri, nto leyo echaphazela ukusebenza kwebhetri kunye nobomi. ” U-Li Jia, umongameli weshishini lehlabathi le-Xingdong Lithium Battery, uthe ukusombulula ingxaki yobushushu obuphantsi beebhetri. , into ephambili kukuphuhlisa izinto ezinokunyamezela kobushushu obuphantsi.

Ukuqala kwimathiriyeli kunye neminye imiba, iXingdong Lithium Ibhetri yoyise ubunzima kwaye yaphuhlisa ngempumelelo inani letekhnoloji enelungelo elilodwa lomenzi wechiza. Ikwavelise ngempumelelo i-4 yobushushu obuphantsiiibhetri ze-lithiumenokuthi ihlawuliswe kwaye ikhutshwe kwiindawo eziphantsi kweqondo lokushisa -20 ℃, -25 ℃, -30 ℃, kunye -35 ℃, kunye noluhlu lomthamo we-206Ah ukuya kwi-314Ah, kunye nentlawulo ehambelanayo kunye nokusebenza ngokufanelekileyo okukhulu kune-97%, 95 I-%, i-95%, kunye ne-90%, ngokulandelanayo, ikhokela ishishini.

Ukuba sijonga ngakumbi imfihlo, siya kufumanisa ukuba indibaniselwano yegolide yeXingdong lithium ibhetri "4+N" idlale indima ebaluleke kakhulu. I-4 ibhekisa kwiiteknoloji ezine ezingundoqo, kwaye i-N ibhekisa kubuchwepheshe obunamalungelo awodwa abenzi obuninzi obusetyenziswa ngokudibeneyo:

1. Ngokudityaniswa kwe-carbon nanotubes kunye negraphene, iibhetri ye-lithiumi-impedance iyancipha kakhulu, ukuchasana kwangaphakathi ngu-≤0.25mΩ, ukusebenza kwezinga kuphuculwe kakhulu, kwaye kunokuxhasa i-15C yokukhutshwa kwangoku;

2. Itekhnoloji yokugquma i-diaphragm enelungelo lobunikazi yamkelwe ukwenza i-pole piece iboshwe kakhulu ngexesha lokusebenza, ngokufanelekileyo ukuphucula ukhuseleko lwebhetri kunye nokusebenza komjikelo;

3. I-patent in-situ gel electrolyte yamkelwa, kwaye i-initiator kunye ne-coagulant ehambelana ne-lithium iron phosphate ibhetri yongezwa ukwenza ibhetri ixhathise ngakumbi kwiqondo lokushisa eliphantsi, kwaye ibhetri yokusebenza kweqondo lokushisa inokufikelela -35℃～60℃;

4. Inkqubo yokupakisha iyamkelwa, xa kuthelekiswa nenkqubo yokuvuthwa kwendabuko, ukuchasana kwangaphakathi kuncitshiswa nge-30%, ngokuzinza okungcono kwesakhiwo, ukhuseleko oluphezulu, ubomi bomjikelezo obude, kunye nobuninzi bamandla ≥180Wh / kg;

5. Ngamalungelo okuvelisa i-43, inkqubo ye-lithium iron phosphate yamkelwa, idityaniswe neenkqubo ezizodwa, kwaye imveliso ezenzekelayo ngokupheleleyo kunye nemigca yokuvelisa echanekileyo isetyenziselwa ukuqinisekisa ukuhambelana okuphezulu kweeseli zebhetri, kwaye iya kukhuthaza ukuphuculwa okuqhubekayo kunye nokuphuculwa. ukuphindwa kweemveliso.
