NgoJanuwari 8, 2021, uMphathiswa wezoShishino kunye neTekhnoloji yoLwazi, ilungu leSebe lezoShishino kunye neTekhnoloji yoLwazi, uMninimzi u-Xin Guobin, wongamela ukudibanisa izithuthi zombane, wagxininisa ukuba izithuthi zombane eziphantsi kobushushu bokusebenzisa iingxaki ezinxulumene nabathengi, kufuneka zibe "abantu Indawo yokuhamba esisiseko seziko, ingqalelo ephezulu yophando kufuneka iphucule ukusebenza kwebhetri ephantsi kunye nokuphucula ngononophelo isithuthi sokuqhuba; izithuthi, ukuphucula amava omsebenzisi, iiyunivesithi kunye namaziko ophando ukomeleza uphando olusisiseko lwethekhinoloji eqhelekileyo, kunye nenkxaso eyomeleleyo kuphuhliso lwemizi-mveliso. Ubusika obupholileyo obubandayo, imimandla emininzi kwilizwe lam yazisa imozulu epholileyo. Kutshanje, amajelo amakhulu eendaba nawo anike ingxelo yokuba "kubethelwa kwamaza abandayo, abanini bamandla amatsha kwi-Tricky shit" kunye nezinye iibhetri ze-lithium-ion zasebusika.

Iimoto zamandla amatsha ebusika zinikwa amandla ezantsi, kunzima kangakanani ukubiza? Isithuthi samandla esitsha sikhuthaza ukunqanda indlela yokwaphuka? Yiba ngumba ofuna ukusonjululwa kushishino. Ubusika lithium-ion ibhetri amandla-phantsi isenzeko uye wafumanisa ukuba kukho indlela yokuqonda ukuba kwiqondo lobushushu eliphantsi, umsebenzi lithium ion ibhetri yelithium ion eguquguqukayo yehliswa, kwaye ezinye ion lithium ukulahlekelwa umsebenzi, nto leyo nayo eninzi izithuthi amandla amatsha intlawulo. Izizathu zokuba kutheni ungaqhubeli phambili, kunye nonobangela wokutshaja okucothayo.

Ngelo xesha, isisombululo se-electrolytic samandla e-lithium-ion ibhetri iye yaba yi-viscous ngenxa yendawo yokushisa ephantsi, kunye nokusetyenziswa kwamandla e-lithium ion ngexesha lokukhutshwa, okukhokelela kwisithuthi "esisebenzayo". Ekuphenduleni ibhetri "yokunganyamezeli" kwebhetri, iinkampani ezininzi ziye zafunda iintlobo ezahlukeneyo zeenkqubo zokulawula ibhetri ye-thermal, ndiyathemba ukugcina ibhetri ye-lithium-ion eguquguqukayo ukusombulula ingxaki "yoloyiko". Inkqubo yokulawula ibhetri ye-thermal ilinganisa ngokuchanekileyo kwaye ibeka iliso kwiqondo lokushisa kwebhetri, ukutshatyalaliswa kobushushu ngexesha lobushushu bebhetri, ukufudumeza ngokukhawuleza phantsi kweemeko zokushisa eziphantsi.

Nangona kunjalo, kukho okwangoku kwinqanaba lokuqala, kwaye kukho ukungafani kweteknoloji, ixabiso, isikali, inkxaso, kunye namaxabiso eteknoloji, ixabiso, isikali, inkxaso kunye namaxabiso kulo lonke ishishini. Kummandla ongasentla, inkqubo yokulawula i-thermal ineendleko eziphezulu kunye neemfuno ezinzima zenkqubo. Ngexesha elidlulileyo, uHarbin wagxothwa kwinkqubo yebhanki evulekileyo yemoto yombane ecocekileyo yomkhweli.

I-brigade yokuhlangula umlilo "iSatifikethi seNgozi yoMlilo" iyaqaphela: isithuthi asiqhelekanga ngexesha lenkqubo yokutshaja, i-lithium-ion ibhetri yokufudumeza inkqubo yokufudumeza ayiqhelekanga, kwaye izinga lokushisa kwipakethi yebhetri liyaqhubeka nokunyuka, okubangela ukuvutha komlilo. Kwiibhetri ze-lithium-ion zasebusika, i-R <000000> D inkqubo yokulawula ibhetri ye-thermal yindlela enokwenzeka, kodwa ingaba umphumo okanye ingozi yokhuseleko ilindeleke, kodwa kufuneka iphinde iqinisekise. I-Yinlong titanate inokusebenza kakhulu ubushushu obuphantsi ukusombulula izithuthi zamandla amatsha ebusika imingeni yokusebenza, ngaba kukho ibhetri ye-lithium-ion enamandla enokumelana nobushushu obuphantsi? Impendulo ithi.

Ngokutsho kweChaneli yezeMali yeCCTV: i-lithium yesilivere ye-titanate inobushushu obuphantsi obuhle, elona qondo lobushushu lisezantsi kuvavanyo lokulinganisa yi-50 ° C. Ulwakhiwo lwe-lithium titanate luzinzile, kunye ne-lithium ion diffusion passage ye-three-dimensional kunye nomphezulu ayenzi ifilimu ye-slid-liquid interface passivation, kunye nokusebenza kwekinetic kusenokugcina ubushushu obuqhelekileyo kumaqondo aphantsi. Ukutshaja akubangeli isekethe emfutshane okanye ikristale yesebe le-lithium ebangela ukuwohloka kakubi, kunye nokukwazi ukuhlawulisa ngokupheleleyo kunye nokukhupha kuluhlu olubanzi lobushushu obuyi -50 ° C ~ 60 ° C.

Ngokubhekiselele kwizinto ezikhethekileyo zokusingqongileyo kwiidolophu ezisenyakatho ebusika, isithuthi samandla esitsha kufuneka "sicinezele isifo", "ubushushu obuphantsi" lukhetho oluphambili. Amandla amatsha kaYinlong anikezelwe ekuphuhliseni i-lithium titanate, kwaye i-lithium titanate-based lithium-ion ibhetri inoluhlu olubanzi lobushushu, ukhuseleko oluphezulu, ubomi obude, ukuhlawula ngokukhawuleza kunye nezinye iimpawu, isagcina ukusebenza okuzinzile kwindawo ebandayo. Ukusombulula ngempumelelo iingxaki ekusebenzeni kwezithuthi zamandla amatsha.

Kwangelo xesha, iYinlong New Energy Car isebenza kwindawo ebandayo yeHarbin, Hohhot, Baotou, njl. I-teknoloji iqhubela phambili, ixesha lidlulileyo, kwaye isithuthi samandla esitsha siseyinto eqhelekileyo. Ndiyakholelwa kwikamva elingekude, ekusebenzeni nasekusetyenzisweni kwesisombululo sebhetri ye-lithium-ion esekwe kwi-Yinlong New Energy, isithuthi samandla esitsha siya kugqobhoza amatyathanga obusika obubandayo, singenise intwasahlobo eshushu.
