Yuav ua li cas teeb meem yuav tsum tau them sai sai rau thaum khaws cia lithium roj teeb

Cov roj teeb lithium cia siab rau kev txav ntawm lithium ions ntawm electrodes los tsim hluav taws xob hluav taws xob. Kev khaws cia thiab tso tawm ntawm lub zog hluav taws xob no ua tiav los ntawm kev ntxig thiab deintercalation ntawm lithium ions tso tawm los ntawm cov khoom siv zoo rau hauv cov khoom siv tsis zoo, tsis muaj tshuaj lom neeg. , uas yog qhov loj tshaj plaws ntawm cov roj teeb lithium-ion.

Cov yam ntxwv ntawm nws cov roj teeb teb no txiav txim siab tias nws yuav muaj lub neej ntev dua li cov roj teeb nruab nrab. Tsis tas li ntawd, kev xaiv loj ntawm cov khoom siv electrode kuj yog ib qho tseem ceeb ntawm nws. Tsis tas li ntawd, lithium-ion roj teeb lawv tus kheej muaj cov yam ntxwv ntawm miniaturization, lub teeb yuag thiab high voltage. Los ntawm kev xaiv cov khoom siv thiab cov qauv tsim, lub zog tso zis siab tuaj yeem ua tiav. Thiab muaj peev xwm siab, yog li nws muaj peev xwm tsim cov qauv thiab cov yam ntxwv uas haum rau kev siv tiag tiag, uas yog ib qho zoo ntawm lithium-ion roj teeb.

Lub roj teeb lithium-ion yog tsim los ntawm cov khoom siv hluav taws xob zoo li oxidant, cov khoom siv tsis zoo electrode active khoom raws li txo tus neeg sawv cev, electrolyte lithium-ion conductive theem, thiab cais los tiv thaiv luv luv Circuit Court ntawm ob electrodes. Cov hauv qab no yog lithium-ion roj teeb ua piv txwv los qhia txog qhov chaw cia khoom thiab kev ceev faj ntawm lub roj teeb:

Kev Tiv Thaiv Ib puag ncig Kev Tiv Thaiv Kev Tiv Thaiv Tsis txhob muab cov roj teeb fais fab tso rau hauv dej lossis ntxuav nws nrog dej. Nws yog txwv tsis pub muab cov khoom siv hluav taws xob sib xyaw ua ke rau hauv hluav taws lossis ua rau nws mus rau qhov kub thiab txias ib puag ncig ntev, thiab nws yuav tsum tau khaws cia kom deb ntawm qhov cua sov. Nws yog txwv tsis pub khaws cia thiab siv nyob rau hauv ib puag ncig uas muaj hluav taws xob zoo li qub lossis hluav taws xob hluav taws xob siab.
