Cov roj teeb lithium polymer feem ntau yog hu ua lithium polymer roj teeb. Cov roj teeb lithium polymer, tseem hu ua lithium polymer roj teeb, yog hom roj teeb uas muaj tshuaj lom neeg. Lawv yog lub zog siab, miniaturized thiab lub teeb yuag piv rau cov roj teeb li qub. Cov roj teeb lithium polymer muaj cov yam ntxwv tshwj xeeb, kom phim cov kev xav tau ntawm qee cov khoom, ua rau cov duab sib txawv thiab muaj peev xwm ntawm lub roj teeb, tshwj xeeb yog vim li cas cov roj teeb lithium mos yuav kim dua? Tom ntej no, peb yuav txuas ntxiv mus saib cov pob mos lithium polymer roj teeb nqi dua li cov roj teeb zoo tib yam vim li cas thiaj kim?
Polymer lithium roj teeb tuaj yeem ua nyias, qhov loj me thiab qhov sib txawv vim lawv cov electrolyte tuaj yeem ua tau zoo lossis gelled es tsis yog kua, thaum cov roj teeb lithium siv electrolyte thiab yuav tsum muaj cov ntaub ntawv muaj zog raws li cov pob thib ob los tuav cov electrolyte. Yog li ntawd, cov no pab txhawb qhov hnyav ntxiv ntawm lithium roj teeb.
Cov theem tam sim no ntawm cov khoom siv polymer feem ntau yog cov roj teeb lithium, siv aluminium-yas zaj duab xis rau lub plhaub, thaum siv cov organic electrolyte sab hauv, txawm tias cov kua kub heev, nws tsis tawg, vim hais tias aluminium-yas zaj duab xis polymer roj teeb. siv cov khoom los yog gel lub xeev tsis muaj to, nws tsuas yog ruptures. Tab sis tsis muaj ib yam dab tsi kiag li, yog tias lub sijhawm tam sim no siab txaus thiab qhov tsis ua haujlwm luv luv tshwm sim, nws tsis tuaj yeem ua tsis tau rau lub roj teeb los yog tawg, thiab feem ntau muaj kev nyab xeeb nrog cov xov tooj ntawm tes thiab ntsiav tshuaj yog tshwm sim los ntawm cov xwm txheej zoo li no.
Qhov no yog tag nrho qhov chaw ntawm ntau yam kev ua yeeb yam sib txawv ntawm ob. Polymer lithium roj teeb yog cov uas siv cov ntaub ntawv polymer nyob rau hauv tsawg kawg yog ib qho ntawm peb lub ntsiab Cheebtsam: zoo electrode, tsis zoo electrode los yog electrolyte. Polymer txhais tau hais tias siab molecular hnyav, as opposed to lub tswvyim ntawm me me molecules, uas muaj lub zog siab, siab toughness thiab siab elasticity. Cov ntaub ntawv polymer tsim nyob rau theem no rau cov roj teeb polymer feem ntau yog siv hauv cathode thiab electrolyte.
