Tesla co-founder JB Straubel qhuas qhov kev pib ua haujlwm ruaj khov. Lub tuam txhab mus rau pej xeem.
JB Straubel yog Tesla Engineer, Cell thiab Battery Technician. Xyoo 2019, nws tawm ntawm lub tuam txhab los tsim lub tuam txhab lithium-ion roj teeb rov ua dua tshiab. Thiab tam sim no nws yog CEO ntawm cov khoom siv hluav taws xob electrolyte pib: QantumScape.
Yog tias J. B. Strobel tab tom khav txog qee yam, ces tej zaum tsis qaug zog
Thaum lub sij hawm ib qho ntawm cov koom nrog cov rooj sib tham, Elon Musk - ib sab ntawm nws ntawm theem yog J. B. Straubel - qhib siab hais tias thaum ua hauj lwm ntawm Tesla, tej zaum lawv yuav sim tag nrho cov hlwb uas twb muaj lawm. Lawv tau siv cov uas lawv siv, ua nrog Panasonic, tab sis tau kawg lawv caw [cov kws tshawb fawb] uas xav ua pov thawj rau lawv tias lawv muaj cov khoom zoo dua. Txij li thaum lawv tau "kuaj" thiab ua tiav muag hluav taws xob tsheb, lawv muaj kev nkag siab zoo txog qhov lawv tham txog.

Tam sim no, tom qab tawm hauv Tesla, J.B. Straubel yog nyob rau ntawm pawg thawj coj ntawm QuantumScape pib. Thiab nws hais tias:
Lub cell tsim tsis muaj anode thiab cov khoom electrolyte [tsim los ntawm] QuantumScape yog lub zoo nkauj tshaj lithium roj teeb architecture kuv puas tau pom. Lub tuam txhab muaj lub sijhawm los redefine lub roj teeb ntu.
QuantumScape tau nce ntau dua $ 700 lab los ntawm cov neeg lag luam ua lag luam (xws li SAIC thiab Volkswagen) thiab tau dhau mus rau pej xeem. Lub chaw pib tab tom tsim cov khoom siv hluav taws xob uas cog lus siab zog dua li cov lithium-ion kua electrolyte hlwb uas twb muaj lawm:
Cov khoom electrolyte nyob rau hauv lub cell - ntxiv rau txo qhov kev pheej hmoo ntawm hluav taws - thaiv kev loj hlob ntawm lithium dendrites, uas ua rau ib tug luv luv Circuit Court thiab puas hlwb nyob rau hauv. Qhov no txhais tau hais tias cov anode ntawm tes tuaj yeem ua los ntawm cov lithium ntshiab es tsis yog los ntawm graphite lossis silicon li niaj hnub no. Thiab txij li thaum lub zog thauj khoom yog cov lithium ntshiab, lub peev xwm ntawm lub xov tooj yuav tsum nce 1,5-2 zaug piv rau cov lithium-ion li niaj hnub.
Qhov kom zoo dua yog ntau dua: cov khoom siv electrolyte lithium hlau tuaj yeem raug them nrog lub zog siab dua thiab yuav tsum decompose qeeb dua. Vim hais tias cov lithium atoms yuav tsis raug ntes los ntawm graphite / silicon / SEI txheej txheej, tab sis yuav txav mus los ntawm kev ywj pheej.
Thaum QuantumScape tau nthuav tawm rau nws cov tub ua lag luam, tsis txhob cia siab tias lub tuam txhab cov hlwb yuav tsum tau siv sai sai rau cov tsheb. Txawm hais tias cov hlwb tau npaj txhij thiab muaj ib tus neeg xav nyob ua ntej ntawm kev sib tw siv cov khoom QuantumScape, nws yuav siv sijhawm 2-3 xyoos los siv cov kev daws teeb meem. Ntau lub tuam txhab tau tshaj tawm hais tias kev sib txuas hauv lub xeev yog ib zaj nkauj hais txog lub neej yav tom ntej, nyob ib nrab ntawm lub xyoo caum xyoo no:
> LG Chem siv sulfides hauv lub xeev cov hlwb. Khoom siv hluav taws xob ua lag luam tsis pub dhau 2028
Tsim nyog pom, qhia luv luv txog yuav ua li cas cov kua thiab cov khoom electrolyte ua haujlwm:
Qhov no yuav txaus siab rau koj:
