Kev tshawb fawb tshiab los ntawm University College London thiab University of Oxford qhia tau hais tias txawm hais tias cov roj teeb lithium-ion hauv cov e-luam yeeb raug muab pov tseg tom qab siv ib zaug, lawv tuaj yeem tuav lub peev xwm siab tom qab ntau pua lub voj voog.Cov kev tshawb fawb tau txhawb nqa los ntawm Faraday Institute thiab luam tawm hauv phau ntawv journal Joule.
Qhov nrov ntawmpov tseg e-luam yeebtau nce siab hauv tebchaws Askiv txij li xyoo 2021, nrog kev tshawb fawb pom tias qhov nrov ntawm cov luam yeeb e-luam yeeb tau nce 18-fold ntawm Lub Ib Hlis 2021 thiab Plaub Hlis 2022, ua rau txhua lab ntawm cov khoom siv vaping raug pov tseg txhua lub lim tiam.
Pab neeg tshawb fawb tau muaj lub suab hais tias cov roj teeb uas siv rau hauv cov luam yeeb e-luam yeeb tau rov qab tau, tab sis tsis muaj kev tshawb fawb yav dhau los tau ntsuas lub roj teeb lub neej ntawm cov roj teeb lithium-ion hauv cov khoom no.
“Pov tseg e-luam yeebtau tawg nyob rau hauv muaj koob meej nyob rau hauv xyoo tas los no.Txawm hais tias raug muag raws li cov khoom siv pov tseg, peb cov kev tshawb fawb pom tau tias cov roj teeb lithium-ion khaws cia hauv lawv muaj peev xwm raug them thiab tawm ntau dua 450 zaug.Txoj kev tshawb no qhia txog yuav ua li cas kev sib deev vaping yog qhov pov tseg loj ntawm cov peev txheej tsawg, "hais tias Hamish Reid, tus thawj coj ntawm kev tshawb fawb los ntawm Tsev Kawm Ntawv ntawm Tshuaj Engineering, University College London.
Txhawm rau sim lawv txoj kev xav, cov kws tshawb fawb los ntawm University College London thiab University of Oxford tau sau cov roj teeb los ntawm cov khoom siv pov tseg.e-luam yeebnyob rau hauv kev tswj xyuas thiab tom qab ntawd ntsuas lawv siv tib yam cuab yeej thiab cov tswv yim siv los kawm cov roj teeb hauv cov tsheb hluav taws xob thiab lwm yam khoom siv..
Lawv tau tshuaj xyuas lub roj teeb nyob rau hauv lub tshuab tsom iav thiab siv X-ray tomography los qhia nws cov qauv sab hauv thiab nkag siab txog nws cov khoom siv.Los ntawm kev them nyiaj rov qab thiab tso tawm cov hlwb, lawv tau txiav txim siab tias cov hlwb tswj hwm lawv cov khoom siv hluav taws xob zoo li cas thaum lub sijhawm, pom tias qee zaum lawv tuaj yeem rov them ntau pua zaus.
Xib fwb Paul Shearing, tus kws sau ntawv laus ntawm UCL's School of Chemical Engineering thiab University of Oxford, tau hais tias: "Rau peb qhov kev xav tsis thoob, cov txiaj ntsig tau pom tias lub sijhawm ua haujlwm ntev npaum li cas ntawm cov roj teeb no.Yog tias koj siv tus nqi qis thiab tso tawm, koj tuaj yeem pom Yog li, tom qab ntau tshaj 700 lub voj voog, lub peev xwm tuav tau tseem ntau dua 90%.Qhov tseeb, qhov no yog lub roj teeb zoo heev.Lawv tsuas yog muab pov tseg thiab muab pov tseg rau ntawm txoj kev. "
"Qhov tsawg kawg nkaus, cov pej xeem yuav tsum nkag siab txog hom roj teeb uas siv hauv cov cuab yeej no thiab xav tau muab pov tseg kom raug.Manufacturers yuav tsum muab ib tug ecosystem raue-luam yeeb roj teeb rov siv dua thiab rov ua dua tshiab, thiab yuav tsum ua kom cov khoom siv rov ua tau zoo dua qub. "
Xibfwb Shearing thiab nws pab neeg tseem tab tom tshawb nrhiav tshiab, xaiv cov roj teeb siv dua tshiab uas tuaj yeem rov ua dua ib tus neeg yam tsis muaj kev sib kis, nrog rau cov roj teeb uas muaj txiaj ntsig zoo dua qub, suav nrog cov roj teeb lithium-ion, cov roj teeb lithium-sulfur thiab sodium-ion roj teeb. .Txhawm rau daws cov teeb meem thoob plaws lub roj teeb khoom, cov kws tshawb fawb yuav tsum xav txog lub voj voog ntawm lub roj teeb thaum xav txog ib qho kev thov rau cov roj teeb.
