Raws li cov khoom siv electrolyte sib txawv siv hauv cov roj teeb lithium, lawv feem ntau muab faib ua kua lithium ion roj teeb thiab polymer lithium ion roj teeb.

Rechargeable lithium roj teeb yog tam sim no dav siv nyob rau hauv niaj hnub digital cov khoom xws li xov tooj ntawm tes thiab phau computers. Txawm hais tias nws yog 18650 lithium roj teeb lossis lub roj teeb hlau-lithium, nws yuav tsum tsis txhob overcharge thaum siv, txwv tsis pub lub roj teeb yuav puas lossis tawg. Muaj kev tiv thaiv Circuit Court ntawm lub roj teeb kom tsis txhob muaj roj teeb kim. Lithium-ion roj teeb yuav tsum muaj siab heev. Txhawm rau kom ntseeg tau tias qhov kev txiav tawm hluav taws xob yog nyob rau hauv ntxiv lossis rho tawm ib feem pua, cov khoom siv hluav taws xob loj semiconductor tau tsim ntau yam lithium-ion them ICs kom ruaj khov, txhim khu kev qha, thiab them ceev ceev.

Cov xov tooj ntawm tes yeej siv cov roj teeb lithium customized. Kev siv cov roj teeb lithium kom raug yog ib qho tseem ceeb heev kom ntev roj teeb lub neej. Nws tuaj yeem ua rau cov duab sib txawv raws li qhov yuav tsum tau muaj ntawm cov tswv yim sib txawv thiab cov khoom siv, thiab nws yog lub roj teeb uas muaj ntau lub roj teeb hauv series thiab sib npaug. Pab pawg. Qhov ntsuas hluav taws xob ntawm lub roj teeb lithium feem ntau yog 3.7V vim qhov hloov pauv ntawm cov ntaub ntawv, thiab qhov zoo electrode ntawm lithium hlau phosphate roj teeb yog 3.2V. Qhov kawg them voltage thaum them tag nrho yog 4.2V. Qhov kawg tso tawm voltage ntawm lithium roj teeb yog 2.75V-3.0V. Yog tias nws tseem tso tawm qis dua 2.5V, nws yuav dhau los ua kev tawm, thiab overdischarge yuav ua rau lub roj teeb puas.
