Fais roj teeb roj teeb yog qhov kim tshaj plaws ib feem ntawm lub tsheb hluav taws xob.
Nws yog tus nqi siab txhais tau tias cov tsheb hluav taws xob muaj nqi ntau dua li lwm hom roj, uas yog qeeb qeeb ntawm kev saws me nyuam.
Lithium-ion
Lithium-ion roj teeb yog qhov nrov tshaj plaws. Yog tsis muaj kev nthuav dav ntau dhau, lawv tawm thiab rov ua dua li cov electrolyte nqa lithium ions ntawm anode rau catode rau catode rau catode rau cathode, thiab vice versa. Txawm li cas los xij, cov ntaub ntawv siv hauv cathode tuaj yeem sib txawv ntawm cov roj teeb lithium-ion.
LFP, NMC, thiab NCA yog peb qhov sib txawv ntawm cov roj teeb lithium-ion. LFP siv Lithium-phosphate ib yam khoom siv cathode; NMC siv Lithium, manganese, thiab cobalt; Thiab NCA siv npib tsib xee, cobalt thiab aluminium.
Cov txiaj ntsig ntawm cov roj teeb lithium-ion:
Pets Cov neeg pheej yig dua los ua dua li NMC thiab NCA roj teeb.
● Sijhawm 2,500-3,000 puv npo
Tsim kom muaj cov cua sov tsawg dua thaum them nyiaj kom nws tuaj yeem txhawb nqa tus nqi siab dua rau hauv tus nqi nkhaus, ua rau kev puas tsuaj ceev dua yam tsis muaj roj teeb kev puas tsuaj.
● Yuav tsum tau them rau 100% nrog rau kev siv roj teeb me me thaum nws pab ntsuas cov roj teeb ntau dua thiab muaj ntau yam kev kwv yees lfp
Xyoo tas los, Tesla ua tau muab nws cov qauv 3 cov neeg siv khoom hauv Asmeskas kev xaiv ntawm NCA lossis LFP roj teeb. Lub Ncu Ncaim NCA yog 117KG sib zog thiab muab 10 mais ntau dua, tab sis muaj lub sijhawm ntev ntev. Txawm li cas los xij, tesla kuj pom zoo tias NCA roj teeb variant tsuas yog them rau 90% ntawm nws lub peev xwm. Hauv lwm lo lus, yog tias koj npaj yuav siv tag nrho, LFP tseem tuaj yeem yog qhov kev xaiv zoo dua.
Npib tsib xee-hlau hydride
Nickel-hlau hydride roj teeb (sau cov roj ntsha tau hais tias tam sim no yog nyob rau hauv hybrid hluav taws xob tsheb (feem ntau ntawm cov khoom ua si uas feem ntau) raws li cov hluav taws xob hluav taws xob.
Qhov laj thawj tseem ceeb rau qhov no yog tias lub zog ntom ntawm Nimh roj teeb muaj ntau li 40% qis dua lithium-ion roj teeb.
