Tesla co-muvambi JB Straubel anorumbidza iyo yakasimba-nyika yekutanga. Kambani inoenda kuruzhinji.
JB Straubel aive Tesla Engineer, Cell uye Battery Technician. Muna 2019, akasiya kambani kuti agadzire kambani yekudzokorodza bhatiri yelithium-ion. Uye zvino ndiye CEO weiyo yakasimba electrolyte bhatiri yekutanga: QantumScape.
Kana J. B. Strobel ari kuzvitutumadza pamusoro pechimwe chinhu, saka pamwe haana kusimba
Munguva yeimwe yemakokorodzano evagovani, Elon Musk - pedyo naye pachikuva aive JB Straubel - akataura pachena kuti pavanenge vachishanda paTesla, vangangodaro vakaedza maseru aripo. Vakashandisa yavakashandisa, yakagadzirwa nePanasonic, asi zvechokwadi vanokoka [vatsvakurudzi] vangada kuratidza kwavari kuti vane chigadzirwa chiri nani. Sezvo "vakaedza" uye vakabudirira kutengesa motokari dzemagetsi, vane kunzwisisa zviri nani pane zvavari kutaura nezvazvo.

Zvino, mushure mekusiya Tesla, JB Straubel ari pabhodhi revatungamiriri vekutanga QuantumScape. Uye akati:
Iyo sero dhizaini isina anode uye yakasimba electrolyte [yakagadzirwa ne] QuantumScape ndiyo yakanakisa lithium bhatiri dhizaini yandati ndamboona. Iyo kambani ine mukana wekutsanangura patsva chikamu chebhatiri.
QuantumScape yakasimudza mari inopfuura mazana manomwe emamiriyoni emadhora kubva kune vanoisa mari mumakambani (kusanganisira SAIC neVolkswagen) uye ichangobuda pachena. Kutanga kuri kugadzira masero akasimba eelectrolyte anovimbisa huwandu hwesimba repamusoro pane aripo lithium-ion liquid electrolyte masero:
Iyo yakasimba electrolyte muchitokisi - kunze kwekuderedza njodzi yemoto - inovhara kukura kwe lithium dendrites, iyo inotungamirira kupfupi pfupi uye kukanganisa kwemasero mukati. Izvi zvinoreva kuti anode yesero inogona kugadzirwa kubva yakachena lithium kwete kubva graphite kana silicon sezvinoitwa nhasi. Uye sezvo mutakuri wesimba ari pure lithium, kugona kwesero kunofanirwa kuwedzera ne 1,5-2 nguva kana ichienzaniswa neyakajairwa lithium-ion masero.
Kubatsira kwakanyanya: yakasimba electrolyte lithium metal cell inogona kubhadhariswa nesimba repamusoro uye inofanira kuora zvishoma nezvishoma. Nekuti maatomu elithium haazobatwa negraphite / silicon / SEI layer zvimiro, asi anozofamba akasununguka achidzokera kumashure.
Ipo QuantumScape yanga ichiita mharidzo kune vanoisa mari, usatarisira kuti masero ekambani achakurumidza kuiswa kumota. Kunyangwe kana maseru akagadzirira uye paine mumwe munhu anoda kugara pamberi pemakwikwi achishandisa QuantumScape zvigadzirwa, zvinotora makore 2-3 kuita mhinduro. Makambani mazhinji ari kutaura pachena kuti hukama hwakasimba huri rwiyo nezveramangwana riri kure, mukati mehafu yechipiri yemakore gumi aya:
> LG Chem inoshandisa sulfides mumasero akasimba. Solid electrolyte kushambadzira kwete pamberi pe2028
Yakakodzera kuona, sumo pfupi yekuti masero emagetsi uye akasimba e electrolyte anoshanda sei:
Izvi zvinogona kukufadza:
