18650 yog tus qauv lithium-ion roj teeb qauv tsim los ntawm SONY Tuam Txhab hauv Nyij Pooj kom txuag nqi. Ntawm lawv, 18 sawv cev rau txoj kab uas hla ntawm 18 hli, 65 sawv cev rau qhov ntev ntawm 65 hli, thiab 0 sawv cev rau lub cylindrical roj teeb.
18650 lithium roj teeb
Lub neej kev pab cuam ntawm 18650 lithium roj teeb yog ntev heev, nrog lub neej voj voog ntawm ntau tshaj 500 zaug thaum siv ib txwm. Feem ntau, lawv tuaj yeem kav ntev li ob xyoos, uas yog ntau tshaj li ob zaug ntawm cov roj teeb li niaj zaus.
18650 Lithium Battery Classification
Feem ntau 18650 roj teeb tau muab faib ua lithium-ion roj teeb thiab lithium hlau phosphate roj teeb. Lub nominal voltage ntawm lithium-ion roj teeb yog 7v, lub charge cutoff voltage yog 2v, thiab lub nominal voltage ntawm lithium hlau phosphate roj teeb yog 2v, qhov paug tawm voltage yog 6v. Lub peev xwm feem ntau yog 1200mAh -3350mAh, thiab lub peev xwm yog 2200mAh -2600mAh.
lithium roj teeb
Cov roj teeb lithium yog cov roj teeb uas muaj hlau lithium raws li qhov tsis zoo electrode, tseem hu ua lithium hlau roj teeb. Nws yog ib qho tsim nyog sau cia tias cov roj teeb lithium tau muab faib ua cov roj teeb tseem ceeb thiab theem nrab raws li lawv qhov kev teeb tsa. Cov roj teeb lithium thaum ntxov yog cov roj teeb tseem ceeb, tab sis vim yog cov khoom siv tshuaj lom neeg zoo ntawm cov roj ntsha lithium, lawv cov txheej txheem, kev cia, thiab kev siv tau muaj kev xav tau ib puag ncig. Yog li, cov roj teeb lithium tsis tau siv dav tom qab lawv tsim. Nrog rau txoj kev loj hlob ntawm microelectronics technology nyob rau thaum xaus ntawm lub xyoo pua 20th, tus naj npawb ntawm cov khoom siv me me tau nce, ua rau muaj kev xav tau ntau dua rau cov khoom siv hluav taws xob. Cov roj teeb lithium tom qab tau nkag mus rau theem ua haujlwm loj. Cov qauv roj teeb lithium feem ntau ntawm cov neeg siv khoom tam sim no siv cov roj ntsha lithium raws li qhov tsis zoo electrode, manganese dioxide ua cov electrode zoo, thiab lithium ntsev yaj hauv cov kuab tshuaj organic raws li cov electrolyte.
