I know that wet cells in cars has acid and special plates, that i forgot the name of, that when it uses the electricity, the substance changes. When you recharge that, the substances change to the origional substances, but how exactly does a lithium battery, or a laptop battery, or a modern MP3/4 battery get recharged? Please include a resorce if possible, thanks!How does a lithium battery get recharged?Source: Wikipedia ( http://en.wikipedia.org/wiki/Lithium_ion )
Lithium-ion batteries (sometimes abbreviated Li-ion batteries) are a type of rechargeable battery in which the cathode (positive electrode) contains lithium, and the anode (negative electrode)is made of a type of porous carbon. During normal operation, the current flows (when the external circuit is connected) from the anode to the cathode, as in any type of battery. During this process, the battery is discharged and the internal process occurring within the battery is the movement of Li+ ions through the non-aqueous electrolyte and separator diaphragm to the carbon cathode. The lithium ions become deeply embedded in the carbon cathode in a process known as intercalation.
Another source where you could get some info would be at a place like Batteries Plus ( http://www.batteriesplus.com ). They probably have knowledge about this too.
