18650 lithiamu batire Charge discharge mfundo
Mfundo yogwira ntchito ya batri ya lithiamu-ion imatanthawuza za mtengo wake ndi kutulutsa.Batire ikaperekedwa, ma ion a lithiamu amapangidwa pamtengo wabwino wa batri, ndipo ma ion a lithiamu amapita kumtengo woyipa kudzera mu electrolyte.Mpweya monga electrode woipa uli ndi mawonekedwe osanjikiza, omwe ali ndi ma micropores ambiri.Ma ion a lithiamu omwe amafika pa electrode yoyipa amalowetsedwa mu ma micropores a carbon layer.Ma ion a lithiamu akaphatikizidwa, ndiye kuti amakwera kwambiri.
Momwemonso, batire ikatulutsidwa (ie njira yogwiritsira ntchito batire), ion ya lithiamu yomwe ili mugawo la mpweya wa electrode yoyipa idzatuluka ndikubwerera ku electrode yabwino.Ma ion a lithiamu akabwerera ku ma elekitirodi abwino, ndiye kuti mphamvu yotulutsa imakwera.Mphamvu ya batri yomwe timatchula nthawi zambiri ndi mphamvu yotulutsa.
18650 lithiamu batire
Sizovuta kuwona kuti panthawi yolipiritsa ndi kutulutsa mabatire a lithiamu-ion, ma ion a lithiamu ali pakuyenda kuchokera pamtengo wabwino kupita kumtengo woyipa kupita kumtengo wabwino.Ngati tiyerekeza batire ya lithiamu-ion ndi mpando wogwedeza, mbali ziwiri za mpando wogwedeza ndi mizati iwiri ya batri, ndipo lithiamu ion ili ngati wothamanga wabwino kwambiri akuthamanga kumbuyo ndi kutsogolo kumapeto kwa mpando wogwedeza.Chifukwa chake, akatswiri adapatsa batri ya lithiamu-ion dzina lokongola lakugwedeza batire.
