Tesla lab boasts cov ntsiab lus uas tuaj yeem tiv taus ntau lab mais.

Lub chaw tshawb fawb tau ntiav los ntawm Tesla los ua haujlwm ntawm lithium-ion hlwb khav theeb tshiab ntawm tes. Ua tsaug rau NMC cathode (nickel-manganese-cobalt) thiab cov electrolyte tshiab, lawv yuav tsum tiv taus 1,6 lab kilometers ntawm tsheb mileage.

Tam sim no, feem ntau ntawm lub ntiaj teb tsheb siv ntau hom NMC hlwb, thaum Tesla siv cov khoom sib txawv me ntsis: NCA (nickel-cobalt-aluminium). Niaj hnub nimno Tesla roj teeb yuav tsum tiv taus los ntawm 480 mus rau 800 txhiab kilometers ntawm mileage. Txawm li cas los xij, Elon Musk lub hom phiaj kom ntseeg tau tias lawv qhov kev puas tsuaj yog ob zaug qeeb, kom lawv tuaj yeem tiv taus ntau npaum li lub zog thiab lub cev - txog li 1,6 lab mais ntawm mais.

Raws li tau tshaj tawm los ntawm lub portal Electrek (qhov chaw), Jeff Dahn lub chaw kuaj mob, uas tshawb xyuas qhov muaj peev xwm ntawm kev txhim kho Li-ion hlwb rau Tesla, nthuav tawm cov txiaj ntsig ntawm nws txoj haujlwm. Cov hlwb tshiab siv lub "ib leeg siv lead ua" cathode NMC 532 thiab cov khoom siv hluav taws xob siab heev. Tom qab kev sim, uas nyob rau qee kis tau ntev txog peb xyoos, Cov kws tshawb fawb tau pheej hmoo qhov kev thov tias cov hlwb yuav tuaj yeem tiv taus mus txog 1,6 lab mais hauv ib lub tsheb los yog tsawg kawg yog nees nkaum xyoo hauv lub khw muag khoom hluav taws xob.

Txawm hais tias qhov ntsuas kub ntawm lub hlwb ua kom sov txog 40 degrees, lawv khaws cia 70 feem pua ​​​​muaj peev xwm tom qab 3 tus nqi tag nrho, uas yuav tsum txhais rau hauv mileage txog 1,2 lab kilometers. Thaum tswj qhov kub ntawm 20 degrees tom qab kwv yees li 3 lab kilometers ntawm mileage lub peev xwm ntawm cov hlwb yuav tsum poob mus rau approx 90 feem pua ​​​​ntawm thawj lub peev xwm.

> Tesla xav tsim kom muaj li 1 GWh ntawm cov hlwb hauv ib xyoos. Tam sim no: 000 GWh, 28 npaug tsawg dua

Nyob rau hauv ib qho kev sim zoo ib yam, kev lag luam muaj qauv lithium-ion hlwb tiv taus txog 1 lub voj voog, uas yuav tsum tau txhais ua 000 mais ntawm mais. Txawm hais tias nws yuav tsum tau muab ntxiv rau ntawm no tias cov hlwb siv hauv kev lag luam tsheb muaj cov sib txawv ntawm cov electrolytes, lub luag haujlwm tseem ceeb ntawm cov txheej txheem degradation yog qeeb:

Nws yog ib qho tsim nyog nyeem (qhov chaw), vim tias txoj haujlwm npaj kev paub txog lithium-ion hlwb thiab qhia txog qhov kev vam meej uas tau ua dhau los 4-6 xyoo dhau los:

Qhib daim duab: A) daim duab microscopic ntawm NMC 532 hmoov B) microscopic yees duab ntawm lub electrode nto tom qab compression, C) ib qho ntawm cov kuaj 402035 hlwb nyob rau hauv sachets ib sab ntawm lub Canadian ob-duas npib, DOWN, daim duab ntawm sab laug) degradation ntawm cov hlwb kuaj tawm tsam cov qauv cell, DOWN, daim duab txoj cai) cell lifetime nyob ntawm qhov kub thiab txias thaum them nyiaj (c) Jessie E.
