Kev tawm tswv yim ntsuab, ib puag ncig tus phooj ywg thiab cov pa roj carbon tsawg yog ib txwm yog lub hom phiaj ntawm kuv lub teb chaws txoj kev loj hlob ntawm kev lag luam thiab kev sib raug zoo. Tshwj xeeb tshaj yog nyob rau hauv xyoo tas los no, raws li kev txhawb nqa ntawm ntau txoj cai zoo xws li lub teb chaws dual carbon, lub zog tshiab roj teeb kev lag luam uas ua raws li lub tswv yim ntawm kev loj hlob ntsuab tau tsim sai heev. Raws li qhov xwm txheej no, cov roj teeb lithium-ion tau tshwm sim hauv ntau qhov chaw, yog li kev tiv thaiv ib puag ncig ntawm lithium-ion roj teeb yog dab tsi?
Ua ntej, cov roj teeb lithium-ion muaj ntau dua nyob rau hauv txoj kab nrog kuv lub teb chaws cov kev xav tau tshiab zog ntsuab. Lead-acid roj teeb muaj cov khoom siv lead ua, uas yuav ua phem rau ib puag ncig ib zaug. Lead-acid roj teeb muaj cov hlau hnyav xws li mercury, lead, cadmium, thiab npib tsib xee, nrog rau cov tshuaj electrolyte xws li acids thiab alkalis, uas ua rau muaj kev phom sij rau tib neeg lub cev thiab ib puag ncig ecological rau ntau qib. Txoj kev tsim cov roj teeb lithium-ion yeej ib txwm tawm tswv yim ntsuab thiab kev tiv thaiv ib puag ncig, thiab ntau tus phooj ywg zoo nyob rau hauv cov nqe lus ntawm kev rov ua dua thiab siv, thiab muaj ntau dua nyob rau hauv txoj kab nrog lub teb chaws ntsuab kev loj hlob yuav tsum tau rau lub zog tshiab.
Thib ob, cov khoom siv raw khoom siv hauv cov roj teeb lithium-ion muaj xws li lithium hlau phosphate, lithium nickel cobalt manganate, lithium nickel cobalt aluminate, graphite, thiab lwm yam. Ntawm lawv, lithium hlau phosphate yeej tsis muaj cov hlau hnyav lossis cov volatiles thiab lwm yam khoom. nws yog ib qho yooj yim rau recycled thiab ua rau cov roj teeb. Nws muaj kev cuam tshuam tsawg dua rau ib puag ncig thiab tuaj yeem hu ua ib puag ncig tus phooj ywg roj teeb.
Thib peb, lithium-ion roj teeb muaj plaub yam khoom tseem ceeb, uas yog qhov zoo electrode, tsis zoo electrode, separator, thiab electrolyte. Ntawm lawv, LiPF6 yog cov khoom siv electrolyte tshaj plaws hauv kev lag luam lithium-ion roj teeb. Nws muaj hluav taws xob zoo conductivity thiab electrochemical stability, thiab muab pov tseg. Lub roj teeb muaj cov yam ntxwv zoo xws li kev tuav yooj yim thiab muaj kev cuam tshuam me me rau ntawm ib puag ncig ecological. Yog li ntawd, piv nrog cov pa roj teeb, lithium-ion roj teeb muaj kev nyab xeeb zoo ib puag ncig.
