Cov roj teeb lithium-ion raug kev puas tsuaj loj thaum ua haujlwm ntawm qhov kub qis dua xoom degrees Celsius, txwv tsis pub siv cov khoom siv hluav taws xob hauv huab cua daus thiab qhov siab siab.
Txhawm rau txhim kho qhov ntsuas kub qis ntawm lithium-ion roj teeb, ob txoj hauv qab no tau siv tam sim no:
1) Ntxiv cov additives los txhim kho qhov kub thiab txias ntawm cov electrolyte;
2) Sab nraud cua sov thiab rwb thaiv tsev ntawm lub roj teeb.
Tsim ib lub roj teeb lithium hlau phosphate uas tuaj yeem ua haujlwm ib txwm nyob ntawm qhov qis 30 degrees, rhuav tshem qhov chaw nyob hauv khw hauv ib qho poob. Nws yog tsim nyog hais tias qhov rho tawm 30 degrees yog qhov txawv ntawm cov roj teeb uas tsis tshua muaj siab (customizable) cov khoom lag luam hauv khw. Low-temperature batteries Nws yog qhov kub thiab txias tiag tiag.
Recommended lithium batteries that can be used at minus 40°C>>
Los ntawm kev siv cov mis uas muaj cov khoom siv hluav taws xob thiab lwm yam khoom siv tshwj xeeb, ua ke nrog cov thev naus laus zis tshiab, lub roj teeb tseem tuaj yeem tso tawm tau zoo ntawm qhov kub thiab txias, thiab qhov tso tawm muaj peev xwm ntawm {{0}} degree ntawm 0.2C tshaj qhov pib muaj peev xwm. 90 feem pua, 95 feem pua ntawm -30 degree . Ua haujlwm kub yog -40 degree ~ 55 degree . Ua ke nrog lub neej voj voog siab ntawm lithium hlau phosphate roj teeb nws tus kheej, nws daws cov teeb meem ntawm ntau cov khoom lag luam hauv ib qho poob.
Tsawg kub lithium roj teeb yam ntxwv:
1. Siv tshuab superposition, tsis tshua muaj kev tiv thaiv sab hauv;
2. -40 degree 0.2C tso tawm, qhov tso tawm muaj peev xwm tshaj 90 feem pua ntawm qhov pib muaj peev xwm;
3. -50 degree 0.2C tso tawm, qhov tso tawm muaj peev xwm tshaj 75 feem pua ntawm qhov pib muaj peev xwm;
4. Dav ua haujlwm kub ntau, -40 degree txog 55 degree;
5. tuaj yeem them rau ntawm -40 degree ;
6. Cov tshuaj lithium hlau phosphate yog siv, uas muaj kev nyab xeeb thiab lub neej ntev;
7. Muaj feem xyuam rau kev tshawb fawb txog keeb kwm yav dhau los, kev cawm siav, cov neeg hlau tshwj xeeb, cov cuab yeej tshwj xeeb, cov cuab yeej kho mob thiab lwm yam haujlwm
