Woyambitsa nawo Tesla JB Straubel amayamika kuyambika kwa boma. Kampaniyo imapita pagulu.
JB Straubel anali Tesla Engineer, Cell and Battery Technician. Mu 2019, adasiya kampaniyo kuti apange kampani yobwezeretsanso batire ya lithiamu-ion. Ndipo tsopano ndiye CEO wa batire yolimba ya electrolyte: QantumScape.
Ngati J. B. Strobel akudzitamandira ndi chinachake, ndiye kuti mwina si wofooka
Pamsonkhano wina womwe adagawana nawo, Elon Musk - ndi JB Straubel pafupi naye pa siteji - adanena poyera kuti akugwira ntchito pa Tesla, mwina adayesa selo lililonse lomwe linalipo. Anagwiritsa ntchito zomwe adagwiritsa ntchito zopangidwa ndi Panasonic, koma ndithudi amapempha [ofufuza] omwe angafune kutsimikizira kwa iwo kuti ali ndi mankhwala abwino. Chifukwa "ayesa" ndikugulitsa bwino magalimoto amagetsi, amadziwa bwino zomwe akunena.
JB Straubel pantchito yoyambirira pa Tesla Roadster (c) Tesla cell mapaketi
Tsopano, atachoka ku Tesla, JB Straubel ali pa board of directors of the startup QuantumScape. Ndipo adati:
Mapangidwe a cell opanda anode ndi electrolyte olimba [opangidwa ndi] QuantumScape ndiwokongola kwambiri kamangidwe ka batri la lithiamu komwe ndidawonapo. Kampaniyo ili ndi mwayi wofotokozeranso gawo la batri.
QuantumScape yakweza ndalama zoposa $ 700 miliyoni kuchokera kwa ogulitsa makampani (kuphatikiza SAIC ndi Volkswagen) ndipo yangopita poyera. Kuyambako kukupanga maselo olimba a electrolyte omwe amalonjeza kuchuluka kwa mphamvu kuposa ma cell a lithiamu-ion amadzimadzi a electrolyte:
Electrolyte yolimba mu selo - kuwonjezera pa kuchepetsa chiopsezo cha moto - imalepheretsa kukula kwa lithiamu dendrites, zomwe zimabweretsa maulendo afupikitsa ndi kuwonongeka kwa maselo mkati. Izi zikutanthauza kuti anode ya selo imatha kupangidwa kuchokera ku lithiamu yoyera, osati graphite kapena silicon, monga momwe zimachitikira lero. Ndipo popeza chonyamulira mphamvu ndi lifiyamu yoyera, mphamvu ya cell iyenera kuwonjezeka ndi 1,5-2 nthawi poyerekeza ndi ma cell a lithiamu-ion.
Ubwino wake ndi waukulu: selo lolimba la electrolyte lithiamu zitsulo limatha kuperekedwa ndi mphamvu yayikulu ndipo liyenera kuwola pang'onopang'ono. Chifukwa maatomu a lifiyamu sadzagwidwa ndi ma graphite / silicon / SEI wosanjikiza, koma aziyenda momasuka mmbuyo ndi mtsogolo.
Ngakhale QuantumScape yakhala ikupanga zowonetsera kwa osunga ndalama, musayembekezere kuti ma cell a kampaniyo atengedwe mwachangu m'magalimoto. Ngakhale maselo ali okonzeka ndipo pali wina amene akufuna kukhala patsogolo pa mpikisano pogwiritsa ntchito mankhwala a QuantumScape, zidzatenga zaka 2-3 kuti athetse vutoli. Makampani ambiri amanena momveka bwino kuti mgwirizano wokhazikika ndi nyimbo yamtsogolo, pafupi theka lachiwiri la zaka khumi izi:
> LG Chem imagwiritsa ntchito sulfide m'maselo olimba. Kutsatsa kolimba kwa electrolyte kusanachitike 2028
Zoyenera kuwona, mawu oyamba achidule a momwe maselo amadzimadzi ndi olimba a electrolyte amagwirira ntchito:
Izi zingakusangalatseni:
