Cov tsheb hluav taws xob muab txoj hauv kev rau huab cua zoo dua, txo cov nqi roj thiab suav nrog pawg tshiab loj hlob rau cov neeg tsim tsheb. Tab sis nrog kev hloov mus rau kev thauj mus los hauv hluav taws xob los ntawm kev sib tw tshiab: Cov tsheb nrog lithium ion roj teeb tuaj yeem ua rau muaj kev phom sij tshwj xeeb thaum lawv ntes hluav taws.
Qhov xwm zoo yog lub roj teeb hluav taws xob tsheb hluav taws xob tsis tshwm sim ntau zaus.
Tus Thawj Saib Xyuas Haujlwm ntawm EV FireSafe hauv Melbourne, Australia, Emma Sutcliffe, hais tias cov kws tshawb fawb xav tau cov ntaub ntawv ntxiv los txiav txim siab txog qhov hluav taws kub, tab sis cov kev tshawb fawb ua ntej qhia tias hluav taws kub hauv tsheb hluav taws xob muaj tsawg.
Kev tshawb fawb los ntawm lwm lub tuam txhab, AutoinsuranceEZ, hais tias lub roj teeb hluav taws xob tsheb tsuas muaj .03% txoj hauv kev ntawm qhov hluav taws xob, piv rau cov tsheb sib tsoo hauv lub cav 1.5%. Hybrid hluav taws xob, uas muaj ob lub roj teeb hluav taws xob siab thiab lub tshuab hluav taws xob sab hauv, muaj 3.4% qhov tshwm sim ntawm hluav taws xob tsheb raws li lawv txoj kev tshawb fawb.
Txawm li cas los xij, thaum hluav taws tshwm sim, cov tsheb fais fab nrog cov roj teeb lithium ion kub dua, sai dua thiab xav tau dej ntau dua kom ncav cuag qhov kawg tua, Sutcliffe hais. Thiab cov roj teeb tuaj yeem rov ua kom kub hnyiab tau ntau teev lossis txawm hnub tom qab qhov hluav taws kub tswj tau pib, tawm hauv cov chaw khaws cia, cov khw kho mob thiab lwm yam muaj kev pheej hmoo.
Chas McGarvey, Tus Thawj Saib Xyuas Hluav Taws Xob ntawm Pennsylvania Lub Tsev Haujlwm Saib Xyuas Hluav Taws Xob qis Merion, hais rau CNBC tias ib qho Tesla Model S Plaid hluav taws nws lub tuam tsev tau tuav hauv 2021 kub kub heev uas nws yaj txoj kev hauv qab nws.
Sutcliffe hais rau CNBC, "Ntau lub sijhawm cov neeg tua hluav taws thiab cov koom haum tua hluav taws tsuas yog xav kom paub txog nws." Nrog ntau tus qauv tshiab los tsoo txoj kev, McGarvey tus thawj coj tua hluav taws hauv Pennsylvania tau hais tias, "Peb tseem tab tom sim ntes tag nrho cov khoom no. Tab sis nws hloov yuav luag txhua hnub! ”
Tus Thawj Coj ntawm Maryland's Energy Institute, Eric Wachsman, hais tias qhov ua tau zoo uas ua rau cov roj teeb lithium ion muaj zog txaus los txav lub tsheb neeg caij tsheb kuj tuaj yeem ua rau lawv tsis muaj teeb meem - tshwj xeeb tshaj yog tias cov roj teeb hauv lawv puas lossis puas lawm.
Lithium ion roj teeb hlwb muaj cov khoom siv hluav taws xob nyob ze ua ke, uas ua rau muaj feem yuav luv luv, nws hais tias, thiab lawv tau ntim cov kua hluav taws xob hluav taws xob.
Nws tau hais tias "Cov kua nplaum no tuaj yeem nkag mus rau hauv qhov hu ua qhov kub ntxhov uas nws nyuam qhuav pib npau taws, thiab qhov ntawd ua rau muaj hluav taws," nws hais.
Cov tsheb hluav taws xob suav nrog cov roj teeb tswj kev tswj xyuas kom muaj kev ua haujlwm zoo rau cov roj teeb hluav taws xob siab sab hauv, thiab cov tshuab tswj xyuas cov roj teeb ceev npaum li cas thiab tso tawm. Kev txhim kho rau lawv nrog rau cov roj teeb lub hlwb lawv tus kheej cog lus tias yuav ua rau EVs nyab xeeb dua.
Tesla tsis ntev los no tshaj tawm tias nws tau hloov los ntawm lithium ion roj teeb hlwb rau lithium hlau phosphate (LFP) roj teeb. Lwm cov tuam txhab tsheb loj suav nrog Ford, thiab VW kuj tseem hloov LFPs rau cov qauv nickel lossis cobalt siv hauv qee lub tsheb hluav taws xob.
Paul Christensen, tus xibfwb ntawm electrochemistry ntawm Newcastle University tau hais tias "Cov no feem ntau ntseeg tau tias muaj kev nyab xeeb dua," said Paul Christensen, tus xibfwb ntawm electrochemistry ntawm Newcastle University uas nws kev tshawb fawb tsom mus rau lithium ion roj teeb hluav taws xob thiab kev nyab xeeb.
Thaum kawg, nws ntseeg hais tias, tag nrho cov tsheb hluav taws xob muaj lub caij nyoog kom muaj kev nyab xeeb dua li cov roj av- lossis cov qauv hluav taws kub uas lawv hloov.
"Peb tau siv sijhawm ntev los nkag siab txog qhov txaus ntshai thiab kev phom sij cuam tshuam nrog cov roj av thiab cov tsheb diesel. Peb yuav tau kawm sai dua yuav daws cov teeb meem nrog cov tsheb fais fab. Tab sis peb yuav."
