1. Cov khoom siv raw

Polymer roj teeb hais txog kev siv cov khoom siv polymer hauv tsawg kawg yog ib qho ntawm peb yam tseem ceeb: zoo electrode, tsis zoo electrode lossis electrolyte. Polymer txhais tau tias qhov hnyav molecular loj, thiab nws cov ntsiab lus sib thooj yog cov molecules me me, polymer muaj lub zog siab, siab toughness thiab siab elasticity. Polymer roj teeb cathode cov ntaub ntawv ntxiv rau kev siv cov inorganic compounds rau lithium-ion roj teeb, tab sis kuj conductive polymer; polymer roj teeb electrolytes yog polymer electrolytes (khoom los yog gel lub xeev) thiab organic electrolyte, lithium-ion roj teeb siv electrolyte.

2.Txoj kev sib txawv

Polymer lithium-ion roj teeb tuaj yeem ua nyias, txhua qhov chaw thiab ib puag ncig, yog vim li cas nws cov electrolyte tuaj yeem ua tau zoo lossis gel lub xeev tsis yog kua, thaum cov roj teeb lithium-ion siv electrolyte, rau lub plhaub muaj zog raws li cov ntim khoom thib ob kom haum rau electrolyte. . Yog li ntawd, qhov no kuj ua rau lithium-ion roj teeb ntxiv ib feem ntawm qhov hnyav.

3. Kev nyab xeeb

Lub polymer tam sim no feem ntau yog mos pob roj teeb, siv aluminium-yas zaj duab xis raws li lub plhaub, thaum 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, tsuas yog ntuj rupture. Tab sis txhua yam tsis yog qhov tseeb, yog tias lub sijhawm tam sim no siab txaus, luv luv Circuit Court, lub roj teeb spontaneous combustion los yog tawg yog tsis yooj yim sua, xov tooj ntawm tes thiab ntsiav tshuaj PC kev nyab xeeb xwm txheej yog tshwm sim los ntawm qhov teeb meem no. Thiab cov roj teeb lithium hlau phosphate tau raug kuaj xyuas kev nyab xeeb, txawm tias muaj kev sib tsoo hnyav yuav tsis tawg.

4. cell voltage

Raws li cov roj teeb polymer siv cov ntaub ntawv polymer, tuaj yeem ua rau hauv lub xovtooj ntawm ntau txheej ua ke kom ua tiav qhov hluav taws xob siab, thiab lithium-ion roj teeb hlwb nominal muaj peev xwm yog 3.6V, kom ua tiav qhov hluav taws xob siab hauv kev xyaum, nws yog ib qho tsim nyog los txuas ntau lub hlwb hauv series. los tsim lub zoo tagnrho high-voltage platform.

5.Kev coj ua

Lub ionic conductivity ntawm cov khoom electrolyte ntawm polymer lithium-ion roj teeb yog tsawg. Tam sim no, qee cov additives feem ntau yog ntxiv los ua nws cov gel electrolyte los txhim kho cov conductivity. Qhov no tsuas yog ntxiv cov ionic conductivity tshiab, tsis zoo li cov roj teeb lithium-ion, uas tuav tus nqi ruaj khov ntawm kev coj ua yam tsis muaj kev cuam tshuam los ntawm qhov zoo ntawm cov khoom siv.
