A lithium-ion battery (sometimes abbreviated Li-ion battery) is a type of rechargeable battery in which the cathode (positive electrode) contains lithium. The anode (negative electrode) is generally made of a type of porous carbon.

A lithium-ion battery (sometimes abbreviated Li-ion battery) is a type of rechargeable battery in which the cathode (positive electrode) contains lithium. The anode (negative electrode) is generally made of a type of porous carbon.
During discharging, the current flows within the battery (when the external circuit is connected) from the anode to the cathode, as in any type of battery: the internal process is the movement of Li+ ions from the anode to the cathode, through the non-aqueous electrolyte and separator diaphragm.
During charging, an external electrical power source (the charging circuit) forces the current to pass in the reverse direction; the positive terminal from the charging circuit has to be connected to the cathode of the battery, and the anode has to be connected to the negative terminal of the external circuit. The lithium ions then migrate from the cathode to the anode, where they become embedded in the porous electrode material in a process known as intercalation....
