Horumarka weyn: 500Wh/kg baytari birta lithium, si rasmi ah loo bilaabay!

Saaka, CCTV's "Chao Wen Tianxia" ayaa sii daysay,batari birta lithium otomaatig ah oo caalami ah oo tartan ku jirakhadka wax soo saarka ayaa si rasmi ah looga furay Hefei.Khadka wax soo saarka ee la bilaabay waqtigan wuxuu gaadhay horumar weyn oo ku saabsancufnaanta tamarta jiilka cusub ee baytariyada birta lithium500Wh/kg.Waxaa la fahamsan yahay in tani ay tahay khadka wax soo saarka ee ugu horreeya ee loogu talagalay soo saarista batariyada birta lithium ee tooska ah ee Shiinaha iyo xitaa adduunka.

Professor Zhang Yuegang oo ka tirsan jaamacadda Tsinghua ayaa goobta ka sheegay in isbeddelka tamarta caalamiga ah iyo cusboonaysiinta, dhibaatada "walaaca dulqaadka" ay sii wadaan inay riixaan xuduudaha tiknoolajiyada warshadaha, oo u baahan cufnaanta tamarta batteriga si ay u sii socoto.Beteriyada birta lithium waxay isticmaalaan lithium bir saafi ahSida electrode-ka xun, oo leh awood gaar ah oo aragti ultra-sare leh iyo awood aad u hooseeya, taas oo ka dhigaysa baytariyada birta lithium la filayoin ka badan labanlaab tirada safarka ee baabuurta korontada. Waa tignoolajiyada horumarsan ee warshadaha batteriga ee hadda jira. jihada horumarka muhiimka ah.

Furitaanka buuxa ee birta birta lithium ee khadka wax soo saarka tooska ah ee Hefei waxay muujineysaa in ShiinahaAwoodda gaarsiinta dufcadda 500 Wh/kg-dhamaadka sare ee nooca tamarta nooca tamarta wax soo saarka ayaa hoggaanka u qabtay adduunka, waxayna xaqiiqsadeen horumarinta baytariyada birta lithium ee heerka shaybaarka (TRL3) si ay u horumariyaan heerka gaarsiinta badeecada (TRL3) TRL6-8).Mustaqbalka, alaabooyinka ayaa la filayaa inay door weyn ka ciyaaraan duulista korantada, gawaarida tamarta cusub iyo warshadaha kale.Khadkan wax soo saarka ee u heellan ee laga hirgeliyay Hefei wuxuu sidoo kale kor u qaadi doonaa cusboonaysiinta warshadaha iyo horumarinta tayada sare leh, taasoo keenaysa fursado badan oo si buuxda loogu hawlgelinayo xaaladaha codsiga hoose ee baytariyada tamarta tamarta cusub.

Marka loo eego aqoonta korontada, khadka wax soo saarka gaarka ah ee 500Wh / kg wax soo saarka batari birta lithium si toos ah waxaa xaqiiqsaday Anhui Mengwei New Energy Technology Co., Ltd. oo ku yaal Feiqidi Sayniska iyo Teknolojiyadda Magaalada, Aagga Horumarinta Dhaqaalaha, Magaalada Hefei.Bishii Juun ee sannadkii hore, Anhui Mengwei New Energy Technology Co., Ltd. wuxuu gaadhay horumar weyn oo cufnaanta tamarta jiilka cusub ee baytariyada birta lithium ee 500Wh/kg.Khadka wax soo saarka ee maanta ee loogu talagalay soosaarka baytariyada birta lithium ee otomaatiga ah ayaa muujinaya in shirkadda 500Wh/kg baytariyada birta lithium ay si rasmi ah u leedahay.galay marxaladda wax-soo-saarka baaxadda ganacsiga.

Sida ku cad aqoonta korantada,November 2021, Anhui Mengwei New Energy Technology Co., Ltd. iyo Hefei Dhaqaalaha iyo Horumarinta Tiknoolajiyada Zone heshiis maalgashi ee nidaamka cusub awoodda batteriga R & D iyo mashruuca saldhigga wax soo saarka, iyo nidaamka Mengweixin batteriga awoodda R & D iyo mashruuca saldhigga wax soo saarka si rasmi ah u degay Hefei.Sida sahamiye ka mid ah baytariyada birta lithium, bilaabista tamartabaytariR&D iyo mashruuca saldhigga wax soo saarka ee nidaamka Mengweixin ayaa calaamad u ah in lithium-ka ugu horreeya adduunkabaytariyada birta ah ayaa hogaamin doona xaqiijinta wax soo saarka baaxadda weyn ee Hefei.

Kooxda xudunta u ah Mengwei New Energy waxa ay ka kooban yihiin hibo saynis iyo teknooloji iyo xirfadlayaal warshadeed oo ka socda jaamacado si fiican loo yaqaan iyo shirkado bartilmaameedyo ah oo gudaha iyo dibadda ah sida Jaamacadda Tsinghua, Jaamacadda Sayniska iyo Tignoolajiyada Shiinaha, Akadeemiyada Sayniska Shiinaha, iwm.Kooxdu waxay awood u leedahay hal-abuurnimada tignoolajiyada baytari birta lithium iyo wax soo saarka baaxadda weyn, waxayna leedahay tiro ka mid ah tikniyoolajiyada hormuudka u ah tartan caalami ah ee dhinacyada la xiriira sida lithium batteriga cathode iyo naqshadaynta walxaha anode, hagaajinta korantada, wax ka beddelka diaphragm, wax soo saarka unugyada iyo caqliga. wax soo saar otomaatig ah. .

Waa maxay fikradda 500 Wh/kg?Sida laga soo xigtay warbixinnada, qaadashada 2019 TeslaNooca S/X nooca dheer ee nooca safarka ugu dheer ee hadda iibka ah tusaale ahaan, cufnaanta tamarta guud ee unugga batteriga ee la isticmaalo waa qiyaastii 243 Wh/kg.Cufnaanta tamarta batteriga waxay ku dhowdahay 500 Wh / kg, taas oo ah muhiimad la taaban karo, taas oo ah, waxay ku dhawaan kartaa labanlaabida kala-guurka ee gaadiidka korontada ee hadda jira..

Beteriyada birta lithium waa noocyo cusub oo baytariyada leh lithium bir ah oo ah electrode taban. Warshadaha guud ahaan waxay aqoonsan yihiin in baytariyada adag-state noqon doonaa technology batari jiilka soo socda, iyo electrolytes adag-state kaliya si dhab ah ka faa'iidaysan karaan cufnaanta tamarta sare marka lagu daro biraha lithium electrodes negative.Anhui Mengwei New Energy ayaa horay u sii deysay ganacsiyeynta baytariyada birta lithium, si firfircoon u furay "maylkii ugu dambeeyay" ee codsiyada shaybaadhka iyo ganacsiga, waxayna qorsheyneysaa in ay bilowdo ganacsi ee tignoolajiyada batteriga adag ee gobolka si ay u bixiso tayo sare iyo miisaan fudud. awoodda koronto ee diyaaradaha iyo gaadiidka.Dhanka amaanka, taas oo shacabkaWaxay aad uga welwelsan tahay, Mengwei New Energy baytarigiisa birta lithium sidoo kale wuxuu leeyahay waxqabad aad u fiican.Haddi ay caqabad ku tahay xadka heerkulka hooseeya iyo heerkulka sare, ama tijaabooyinka badbaadada sida daloolinta irbada birta, tignoolajiyada baytariyada birta ee Mengwei New Energy waxa ay gaadhay heerka hogaaminta caalamiga ah.
