Dab tsi yog qhov zoo ntawm lithium-ion roj teeb?

1) High voltage

Lub zog ua haujlwm ntawm ib lub roj teeb yog siab li 3.7-3.8V (3.2V rau lithium hlau phosphate), uas yog 3 npaug ntawm Ni-Cd thiab Ni-MH roj teeb.

2) Loj dua lub zog

Lub zog tshwj xeeb uas tuaj yeem ua tiav yog li 555Wh / kg, uas yog, cov khoom tuaj yeem ncav cuag lub peev xwm siab tshaj 150mAh / g (3-4 zaug Ni-Cd, 2-3 zaug Ni-MH), uas yog nyob ze rau nws cov nqi theoretical. Kwv yees li 88 feem pua.

3) Lub neej ua haujlwm ntev

Feem ntau, nws tuaj yeem ncav cuag ntau dua 500 zaug, lossis ntau dua 1000 zaug, thiab rau lithium hlau phosphate, nws tuaj yeem ncav cuag 8000 zaug. Rau cov khoom siv hluav taws xob uas tsis tshua muaj paug tam sim no, lub roj teeb lub neej yuav ua ob npaug rau kev sib tw ntawm cov khoom siv hluav taws xob.

4) Kev ruaj ntseg zoo

Tshiab lithium ion roj teeb

Tsis muaj kuab paug, tsis muaj kev nco. Raws li cov thawj coj ntawm Li-ion, lub lithium roj teeb muaj luv luv vim qhov yooj yim tsim ntawm dendrites, uas txo nws cov ntawv thov teb: Li-ion tsis muaj cadmium, txhuas, mercury thiab lwm yam khoom ua paug rau ib puag ncig; Qee cov txheej txheem (xws li sintering) Ib qho teeb meem loj ntawm Ni-Cd roj teeb yog "nco nyhuv", uas txwv tsis pub siv cov roj teeb hnyav, tab sis Li-ion tsis muaj qhov teeb meem no.

5) Kev tso tawm me me rau tus kheej

Tus kheej tawm tus nqi ntawm tag nrho cov nqi Li-ion khaws cia ntawm chav tsev kub rau 1 lub hlis yog li 2 feem pua, uas yog qis dua li 25-30 feem pua ​​ntawm Ni-Cd thiab 30-35 feem pua ​​ntawm Ni-MH.

6) Fast charging

Lub peev xwm ntawm 1C them hauv 30 feeb tuaj yeem ncav cuag ntau dua 80 feem pua ​​​​ntawm lub peev xwm nominal, thiab ferrophosphorus roj teeb tuaj yeem them rau 90 feem pua ​​​​ntawm lub peev xwm nominal hauv 10 feeb.

7) Ua haujlwm kub

Ua haujlwm kub yog -25 ~ 45 degree . Nrog rau kev txhim kho ntawm electrolyte thiab zoo electrode, nws yuav tsum nthuav mus rau -40 ~ 70 degree .
