Ngale ntsasa, usasazo lweCCTV “Chao Wen Tianxia”,ibhetri yentsimbi ye-lithium ekhuphisana nehlabathi jikeleleumgca wemveliso wemveliso wavulwa ngokusesikweni eHefei.Umgca wemveliso oqaliswe ngeli xesha uzuze impumelelo enkulu kwiUxinzelelo lwamandla kwisizukulwana esitsha seebhetri zesinyithi ze-lithiumye 500Wh/kg.Kuyaqondwa ukuba lo ngumgca wokuqala ozinikeleyo wemveliso we-automated lithium metal ibhetri yokwenziwa e-China nakwihlabathi.
Unjingalwazi uZhang Yuegang weYunivesithi yaseTsinghua uthe kwindawo yokuba ngokuguqulwa kwamandla ehlabathi kunye nokuphuculwa, ingxaki "yokunyamezela ukunyamezela" iyaqhubeka iqhubela phambili imida yeteknoloji yoshishino, efuna ukuba ubuninzi bamandla ebhetri buqhubeke nokunyuka.Iibhetri zesinyithi zeLithium zisebenzisa i-lithium yentsimbi ecocekileyonjenge-electrode engalunganga, ene-ultra-high theoretical umthamo othile kunye nesakhono esiphantsi kakhulu, esenza ukuba iibhetri zentsimbi ze-lithium zilindeleke ukubangaphezu kokuphindwe kabini uluhlu lokuhamba ngeenqwelo zombane.Bubuchwephesha obutsha bokuphumelela kwishishini langoku lebhetri.isikhokelo sophuhliso esibalulekileyo.
Ukuvulwa ngokupheleleyo kwe-lithium yentsimbi yentsimbi yokuvelisa umgca wokuvelisa e-Hefei kubonisa ukuba i-ChinaUmthamo wonikezelo lwebhetshi ye-500 Wh/kg yeemveliso zebhetri zamandla aphezulu esiphelo sohlobo lwamandla aphambili emhlabeni, kwaye waqonda uphuhliso lweebhetri zesinyithi ze-lithium ukusuka kwinqanaba lebhubhoratri (TRL3) ukuya kwiBreakthrough kwinqanaba lonikezelo lwebhetshi yemveliso ( TRL6-8).Kwixesha elizayo, iimveliso kulindeleke ukuba zidlale indima enkulu kwinqwelomoya yombane, izithuthi zamandla amatsha kunye namanye amashishini.Lo mgca wemveliso ozinikeleyo ofakwe ekusebenzeni e-Hefei uya kukhuthaza ukuphuculwa kwemizi-mveliso kunye nophuhliso olukumgangatho ophezulu, ukuzisa amathuba amaninzi okusebenza ngokupheleleyo kweemeko zesicelo esisezantsi sebhetri yamandla amatsha.
Ngokolwazi lombane, umgca wokuvelisa okhethekileyo we-500Wh / kg ngokuzenzekelayo ukuveliswa kwebhetri yentsimbi ye-lithium kufezekiswa yi-Anhui Mengwei New Energy Technology Co., Ltd. ehlala kwi-Feiqidi Science and Technology City, uMmandla woPhuhliso lwezoQoqosho, kwisixeko saseHefei.NgoJuni kulo nyaka uphelileyo, i-Anhui Mengwei New Energy Technology Co., Ltd. iphumelele ukuphumelela okukhulu kubuninzi bamandla kwisizukulwana esitsha seebhetri zesinyithi ze-lithium ze-500Wh / kg.Umgca wemveliso ozinikeleyo namhlanje we-automated lithium ibhetri yentsimbi ibonisa ukuba inkampani ye-500Wh/kg ibhetri yentsimbi ye-lithium isemthethweni.wangena kwinqanaba lemveliso yorhwebo.
Ngokolwazi lombane,ngoNovemba 2021, Anhui Mengwei New Energy Technology Co., Ltd. kunye neHefei Economic and Technology Development Zone batyikitye isivumelwano sotyalo-mali kwinkqubo entsha yebhetri yamandla e-R&D kunye neprojekthi yesiseko sokuvelisa, kunye nenkqubo ye-Mengweixin yebhetri yamandla e-R&D kunye neprojekthi yesiseko sokuvelisa yahlala ngokusesikweni eHefei.Njengomhloli weebhetri zensimbi ze-lithium, ukuqaliswa kwamandlaibhetriI-R&D kunye neprojekthi yesiseko sokuvelisa ye-Mengweixin inkqubo iphawula ukuba i-lithium ehamba phambili yehlabathiiibhetri zentsimbi ziya kukhokela ekuqondeni ukuveliswa kobunzima obukhulu eHefei.
Iqela elingundoqo le-Mengwei New Energy liqulunqwe ngeetalente zenzululwazi kunye nezobuchwepheshe kunye ne-elites kumashishini avela kwiiyunivesithi ezaziwayo kunye namashishini okulinganisa ekhaya nakwamanye amazwe afana neYunivesithi yaseTsinghua, iYunivesithi yeSayensi kunye neTekhnoloji yaseChina, i-Chinese Academy of Sciences, njl.Iqela linamandla okwenza iteknoloji yebhetri ye-lithium entsha kunye nokuveliswa kwemveliso enkulu, kwaye inenani letekhnoloji ehamba phambili ekhuphisanayo kumazwe ngamazwe njenge-lithium yebhetri ye-cathode kunye noyilo lwezinto ze-anode, ukulungiswa kwe-electrolyte, ukuguqulwa kwe-diaphragm, ukuveliswa kweeseli kunye nobukrelekrele. imveliso ezenzekelayo..
Ithini ingqikelelo ye-500 Wh/kg?Ngokweengxelo, ukuthatha i-2019 TeslaImodeli ye-S/X yoluhlu olude olunoluhlu olude lokuhamba ngenqanawa ngoku oluthengiswayo njengomzekelo, ubuninzi bamandla ebhetri esetyenzisiweyo malunga ne-243 Wh/kg.Ubuninzi bamandla ebhetri busondele kwi-500 Wh/kg, enentsingiselo ebonakalayo, oko kukuthi, inokuphantse iphindwe kabini uluhlu lokuhamba ngenqwelo yombane yangoku..
Iibhetri zetsimbi ye-lithium luhlobo olutsha lweebhetri ezine-lithium yensimbi njenge-electrode engalunganga.Umzi-mveliso uyaqonda ngokubanzi ukuba iibhetri zombuso oqinileyo ziya kuba sisizukulwana esilandelayo seteknoloji yebhetri, kwaye i-electrolyte yesimo esiqinileyo inokuthatha kuphela ithuba lokuxinana kwamandla aphezulu xa zidityaniswe ne-lithium metal negative electrode.Anhui Mengwei New Energy uye wabeka phandle urhwebo iibhetri zentsimbi lithium kwangaphambili, ngenkuthalo wavula "imayile yokugqibela" zaselabhoratri kunye nezicelo zorhwebo, kwaye uceba ukuqalisa urhwebo iteknoloji yebhetri eqinileyo ukubonelela ngakumbi umgangatho ophezulu kwaye lightweight. amandla okufakelwa kombane kwinqwelomoya kunye nezithuthi.Ngokwemiqathango yokhuseleko, leyo uluntuexhalabileyo, ibhetri yentsimbi ye-lithium ye-Mengwei New Energy nayo inomsebenzi ogqwesileyo.Nokuba ngumngeni imida ubushushu obuphantsi kunye nobushushu obuphezulu, okanye iimvavanyo zokhuseleko ezifana nentsimbi inaliti ukuhlatywa, Mengwei New Energy kaThixo lithium iteknoloji yentsimbi ibhetri ifikelele kwinqanaba elikhokelayo ngamazwe.
