Namuhla ekuseni, ukusakazwa kwe-CCTV "Chao Wen Tianxia",ibhethri lensimbi ye-lithium eliqhudelana nomhlaba wonkeulayini wokukhiqiza wokukhiqiza wavulwa ngokusemthethweni eHefei.Umugqa wokukhiqiza owethulwe ngalesi sikhathi usuzuze impumelelo enkulu kuukuminyana kwamandla kwesizukulwane esisha samabhethri ensimbi ye-lithium500Wh/kg.Kuyaqondakala ukuthi lona umugqa wokuqala wokukhiqiza ozinikele wokukhiqiza ibhethri ye-lithium yensimbi ezenzakalelayo eChina nasemhlabeni.
UProfesa Zhang Yuegang waseTsinghua University uthe endaweni yesehlakalo ukuthi ngokuguqulwa kwamandla omhlaba wonke kanye nokuthuthukiswa, inkinga "yokukhuthazela kokukhathazeka" iyaqhubeka nokuphoqa imingcele yobuchwepheshe bemboni, edinga ukuthi amandla ebhethri aqhubeke nokukhuphuka.Amabhethri ensimbi ye-lithium asebenzisa i-lithium yensimbi ehlanzekilenjenge-electrode engeyinhle, enamandla athiyori aphezulu aphezulu kakhulu namandla aphansi kakhulu, okwenza amabhethri ensimbi e-lithium alindeleke ukuthingaphezu kokuphindwe kabili uhla lokuhamba lwezimoto zikagesi.Kuwubuchwepheshe obusha obuphambili embonini yamanje yebhethri.isiqondiso esibalulekile sokuthuthukiswa.
Ukuvulwa okugcwele komugqa wokukhiqiza othomathikhi webhethri ye-lithium e-Hefei kukhombisa ukuthi i-ChinaUmthamo wokulethwa kwenqwaba wama-500 Wh/kg imikhiqizo yebhethri yamandla aphezulu ohlobo lwamandla aphezulu usehambe phambili emhlabeni, futhi waqaphela ukuthuthukiswa kwamabhethri ensimbi ye-lithium kusukela esigabeni selabhorethri (TRL3) kuya ku-Breakthrough esigabeni sokulethwa kwenqwaba yomkhiqizo ( I-TRL6-8).Ngokuzayo, imikhiqizo kulindeleke ukuthi ibambe iqhaza elikhulu ekundizeni kukagesi, ezimotweni zamandla amasha kanye nezinye izimboni.Lo mugqa wokukhiqiza ozinikele ofakwe e-Hefei uzophinde ukhuthaze ukuthuthukiswa kwezimboni nokuthuthukiswa kwekhwalithi ephezulu, okuletha amathuba amaningi okusebenza ngokugcwele kwezimo zohlelo lokusebenza ezansi nomfula zamabhethri wamandla amasha.
Ngokolwazi lukagesi, ulayini okhethekile wokukhiqiza we-500Wh/kg othomathikhi webhethri le-lithium metal utholwa yi-Anhui Mengwei New Energy Technology Co., Ltd. etholakala e-Feiqidi Science and Technology City, Economic Development Zone, Hefei City.NgoJuni wonyaka odlule, i-Anhui Mengwei New Energy Technology Co., Ltd. yazuza impumelelo enkulu ekugqileni kwamandla esizukulwane esisha samabhethri ensimbi ye-lithium angu-500Wh/kg.Ulayini wokukhiqiza ozinikele wanamuhla wokwenza ibhethri ye-lithium yensimbi ezenzakalelayo ukhombisa ukuthi ibhethri yensimbi ye-lithium yenkampani engu-500Wh/kg isemthethweni ngokusemthethweni.wangena esigabeni sokukhiqiza ngobuningi bezentengiselwano.
Ngokusho kolwazi lukagesi,ngoNovemba 2021, i-Anhui Mengwei New Energy Technology Co., Ltd. kanye ne-Hefei Economic and Technological Development Zone basayine isivumelwano sokutshalwa kwezimali sohlelo olusha lwebhethri lamandla esistimu i-R&D kanye nephrojekthi eyisisekelo yokukhiqiza, kanye ne-R&D yebhethri yamandla esistimu ye-Mengweixin kanye nephrojekthi eyisisekelo yokukhiqiza izinze ngokusemthethweni e-Hefei.Njengomhloli wamabhethri e-lithium metal, ukwethulwa kwamandlaibhethriI-R&D kanye nephrojekthi eyisisekelo yokukhiqiza yohlelo lwe-Mengweixin imaka ukuthi i-lithium ehamba phambili emhlabeniamabhethri ensimbi azohola ekufezeni ukukhiqizwa kwenqwaba e-Hefei.
Ithimba eliwumgogodla le-Mengwei New Energy lakhiwe ngamathalenta esayensi nezobuchwepheshe kanye nezicukuthwane zezimboni ezivela emanyuvesi aziwayo kanye namabhizinisi okulinganisa ekhaya naphesheya njengeNyuvesi yaseTsinghua, iNyuvesi Yesayensi Nobuchwepheshe yaseChina, i-Chinese Academy of Sciences, njll.Ithimba linamandla okwenza ubuchwepheshe bebhethri yensimbi ye-lithium emisha kanye nokukhiqizwa kwemikhiqizo emikhulu, futhi linobuchwepheshe obuhamba phambili obuncintisana namazwe ngamazwe emikhakheni ehlobene efana ne-lithium battery cathode kanye ne-anode material design, i-electrolyte optimization, ukuguqulwa kwe-diaphragm, ukukhiqizwa kwamaseli kanye nokuhlakanipha. ukukhiqizwa okuzenzakalelayo..
Uyini umqondo we-500 Wh/kg?Ngokwemibiko, ukuthatha i-Tesla ka-2019Imodeli yobude benguqulo ye-S/X enobubanzi obude kakhulu bokuhamba esithengiswayo njengamanje njengesibonelo, ukuminyana kwamandla weseli yebhethri esetshenzisiwe cishe ku-243 Wh/kg.Ukuminyana kwamandla ebhethri kusondele ku-500 Wh/kg, okuwukubaluleka okungokoqobo, okusho ukuthi, lingacishe liphindeke kabili ibanga lokuhamba lemoto yamanje kagesi..
Amabhethri ensimbi ye-lithium ayizinhlobo ezintsha zamabhethri ane-lithium yensimbi njenge-electrode engemihle.Imboni ivamise ukuqaphela ukuthi amabhethri esimo esiqinile azoba ubuchwepheshe bebhethri besizukulwane esilandelayo, futhi ama-electrolyte esimo esiqinile angakwazi ukusizakala ngokuminyana kwawo okuphezulu kwamandla lapho ehlanganiswa nama-electrode e-lithium metal negative.I-Anhui Mengwei New Energy ibeke ukuthengiswa kwamabhethri ensimbi ye-lithium kusenesikhathi, yavula “imayela lokugcina” lezicelo zaselabhorethri nezohwebo, futhi ihlela ukuqala ukuthengiswa kobuchwepheshe bebhethri obuqinile ukuze kuhlinzekwe ngekhwalithi ephezulu futhi engasindi. amandla okufaka ugesi ezindizeni nasezimotweni.Mayelana nokuphepha, okuyinto umphakathiekhathazeke kakhulu ngayo, ibhethri ye-lithium yensimbi ye-Mengwei New Energy nayo inokusebenza okuhle kakhulu.Kungakhathaliseki ukuthi kuyinselele imikhawulo yokushisa okuphansi kanye nokushisa okuphezulu, noma ukuhlolwa kokuphepha okufana nokubhoboza inaliti yensimbi, ubuchwepheshe bebhethri yensimbi ye-lithium ye-Mengwei New Energy sebufinyelele ezingeni elihamba phambili lamazwe ngamazwe.
