1. Lus Txhais ntawm Lithium Polymer Roj teeb

Peb qho ntawm cov roj teeb hluav taws xob: zoo electrode, tsis zoo electrode thiab electrolyte. Qhov uas hu ua lithium polymer roj teeb yog hais txog cov roj teeb uas siv cov khoom siv polymer rau tsawg kawg ib lossis ntau dua ntawm peb yam. Hauv kev tam sim no cov roj teeb lithium polymer

Feem ntau ntawm lawv siv nyob rau hauv qhov zoo electrode thiab electrolyte. Cov khoom siv hluav taws xob zoo siv cov ntaub ntawv conductive polymer lossis cov khoom siv sib xyaw siv hauv cov roj ntsha feem ntau lithium ion roj teeb, cov hluav taws xob tsis zoo feem ntau siv cov roj ntsha lithium lossis cov roj ntsha lithium-carbon intercalation compound, thiab cov electrolyte yog cov khoom zoo nkauj lossis cov xim.

Polymer electrolyte, lossis cov organic electrolyte. Txij li tsis muaj cov electrolyte ntau dhau rau hauv cov roj ntsha lithium polymer, nws yuav ntseeg tau ntau dua thiab ruaj khov.

2. Cov yam ntxwv ntawm lithium polymer roj teeb

Lithium polymer roj teeb (Li-polymer, tseem hu ua polymer lithium-ion roj teeb) muaj ntau yam zoo xws li lub zog tshwj xeeb, miniaturization, ultra-thinness, lub teeb ceeb thawj thiab kev nyab xeeb siab. Raws li cov kev zoo no, lithium polymer roj teeb tuaj yeem ua rau txhua hom duab thiab muaj peev xwm

Lub roj teeb tuaj yeem ua tau raws li qhov xav tau ntawm ntau yam khoom; thiab nws adopts aluminium-yas ntim, thiab cov teeb meem sab hauv tuaj yeem pom tam sim ntawd los ntawm kev ntim khoom sab nraud. Txawm hais tias muaj kev nyab xeeb kev nyab xeeb, nws yuav tsis tawg, tab sis yuav tsuas o tuaj.

 Hauv cov roj teeb polymer, cov roj ntsha hluav taws xob ua lub luag haujlwm ntawm kev cais thiab hluav taws xob: ntawm ib sab tes, nws cais cov khoom zoo thiab tsis zoo xws li daim ntawv cog lus kom tiv thaiv kev tawm ntawm nws tus kheej thiab luv luv hauv roj teeb. Ntawm qhov tod tes, nws yog nyob rau hauv qhov zoo thiab qhov tsis zoo ib yam li electrolyte. Ua cov lithium ions nruab nrab ntawm cov ncej. Polymer electrolyte tsis tsuas yog muaj kev coj ua zoo, tab sis kuj muaj cov yam ntxwv ntawm lub teeb yuag, zoo elasticity, thiab yooj yim zaj duab xis tsim uas muaj cov cim tshwj xeeb rau cov ntaub ntawv polymer. Nws tseem ua raws txoj kev loj hlob ntawm lub teeb yuag, kev nyab xeeb, kev ua haujlwm siab, thiab kev tiv thaiv ib puag ncig ntawm cov khoom siv fais fab.

3. Kev faib tawm cov roj teeb lithium polymer

Lithium polymer roj teeb tuaj yeem raug muab faib ua peb pawg raws li cov electrolyte:

(1)  Gel polymer electrolyte [11] Lithium ion roj teeb, uas ntxiv cov khoom ntxiv rau cov khoom siv roj ntsha electrolyte los txhim kho cov ion conductivity, kom lub roj teeb tuaj yeem siv tau nyob hauv chav tsev kub;

(2)  Cov roj polymer ua cov roj ntsha lithium ion roj teeb, lub tshuab hluav taws xob yog qhov sib xyaw ntawm polymer thiab ntsev, cov ion conductivity ntawm chav tsev kub tsawg, thiab nws tsim nyog rau kev siv kub;

(3) Lithium-ion roj teeb nrog cov khoom sib txuas gel polymer cathode cov ntaub ntawv. Conductive polymer yog siv los ua cov khoom siv cathode. Nws lub zog tshwj xeeb yog 3 zaug ntawm cov roj teeb lithium-ion uas twb muaj lawm. Nws yog lub sijhawm tshiab tshaj plaws ntawm lithium-ion roj teeb.

Vim muaj ntau yam laj thawj xws li thev naus laus zis, tam sim no lithium polymer roj teeb tsom mus rau kev tshawb fawb ntawm kev siv hluav taws xob tsawg thiab tso tawm cov yam ntxwv ntawm cov roj teeb me me. Lub xov tooj tiv thaiv kev tiv thaiv rau cov nruab nrab-rau-loj-muaj peev xwm, nruab nrab- thiab muaj zog hluav taws xob lithium-ion roj teeb tsis tau paub tab [20], ib zaug daws qhov teeb meem Yuav kom daws tau cov teeb meem ntawm kev them nqi, ntsuas thiab tiv thaiv kev tiv thaiv ntawm loj- muaj peev xwm lithium polymer roj teeb, polymer lithium roj teeb yuav zoo siv hluav taws xob tsheb kauj vab. Yog li, nce kev tshawb fawb ntawm cov roj ntsha lithium polymer muaj cov txiaj ntsig zoo hauv kev sib raug zoo thiab nyiaj txiag. Nyob rau tib lub sijhawm, muaj lwm yam uas muaj peev xwm tseem ceeb.
