請問充電池是怎樣放電, 謝謝！

你想問邊款先?!
產生電力通常都係因為一d chemical reaction既電子gain and loss形成閉合電路從而產生電~

以車用電池為例，
就係透過铅(lead)+ 氧化铅(lead oxide) 進行既reaction~
lead loss electron and lead oxide gain electron gain electron,
Pb + 2e- ---------> Pb2+
Pb2+ (PbO2) ------>Pb + 2e-

所以產生到電~

而且和普通電池既分別.充電池可以再充電係因為無 substrate(即係如lead and lead oxide)既流失,加上佢地既reaction係reversible,所以只要調返轉個reaction(即係如lead gain electron, lead oxide loss electron to reproduce d substrate)就可以重新再用ga la~

ps:我學英文.可能有點詞不達意~請見諒..
