Ntau lub luv luv fais siv roj teeb lithium-ion. Lub txim thiab tawm ntawm cov roj teeb lithium-ion yog cov txheej txheem tshuaj uas cov ions taug kev rov qab los ntawm qhov zoo thiab qhov tsis zoo nyob hauv qab ntawm qhov chaw txias. Thaum lub roj teeb lithium-ion raug them, lithium atoms ntawm qhov zoo electrode poob hluav taws xob thiab raug oxidized rau lithium ions, uas nkag mus rau qhov tsis zoo electrode los ntawm electrolyte thiab tau txais hluav taws xob, uas tom qab ntawd txo mus rau lithium atoms. Thaum kev tawm mus, qhov txheej txheem rov qab.
Cov teeb meem xws li flatulence, siab kub thiab tawg ntawm cov roj teeb lithium feem ntau muaj feem xyuam rau kev tshaj, kev them nqi thiab cov loj tam sim no, uas yuav ua rau lub roj teeb puas tsuaj. Thaum overcharge tshwm sim, dhau ob peb lithium atoms nyob rau hauv cov khoom siv anode, uas ua rau muaj kev cuam tshuam ntawm lub roj teeb tas mus li. Ntawm qhov tsis zoo thaum kawg, thaum lithium atoms yog saturated, recharging ua rau lithium hlau ntxiv rau saum npoo ntawm cov khoom tsis zoo, ua rau dendritic muaju. Ua haujlwm dhau sijhawm, lithium dendrites tuaj yeem hno los ntawm lub diaphragm, ua rau lub voj voog luv ntawm qhov taw qhia thiab cathode. Thaum lub sijhawm them dhau, cov roj ntsha thiab lwm yam khoom siv feem ntau yuav tawg kom tsim cov roj, ua rau lub plhaub roj teeb lossis lub siab lub ntsws kom tawg, cov pa oxygen nyob rau saum npoo ntawm qhov tsis zoo lithium atom cov tshuaj tiv thaiv, uas ua rau muaj kev tawg. Zoo li, kev tso tawm ntau dhau kuj tseem yuav ua kev puas tsuaj rau cov khoom siv.
Tsis tas li ntawd, thaum qhov tam sim no loj heev, lithium ions tsis muaj sijhawm los nkag rau hauv cov khoom thiab yuav sib sau ua ke rau saum npoo ntawm cov khoom. Thaum cov lithium ions tau txais hluav taws xob ntau, lawv yuav tsim cov roj ntsha lithium atom muaju nyob rau saum npoo ntawm cov khoom siv. Raws li lithium yog cov hlau nquag tshaj plaws nyob rau ntawm cov rooj sib hais tshuaj, lithium atoms yog yooj yim rau oxidize thiab tawg nrog oxygen.
Ib qho kev nkag siab tsis zoo ntawm cov roj teeb hluav taws xob yog tias thaum hluav taws ntsig txog roj teeb hluav taws xob tshwm sim, nws ib txwm cuam tshuam nrog qhov zoo ntawm lub roj teeb hluav taws xob.
Kev siv ntawm lub roj teeb hluav taws xob, tshwj xeeb tshaj yog cov txheej txheem them, muaj lub zog zoo rau cov roj teeb hluav taws xob. Txawm hais tias qhov zoo ntawm lub roj teeb hluav taws xob tau ua tiav tag nrho raws li cov qauv hauv tebchaws, tus neeg siv tsis tuaj yeem sawv kev ua haujlwm tsis raug cai. Qhov hluav taws kub hauv Beijing' s Chaoyang koog tsev kawm yog ib qho kev xav tsis thoob rau qhov tus cwj pwm siv cov roj teeb hluav taws xob Kev tsis saib xyuas feem ntau ua rau muaj kev puas tsuaj.
