context_page_description: A lithium-ion battery is a lightweight, high-power battery used in computers and mobile phones. It comes in several shapes, although a flat rectangle is most common. It is lighter than the nickel cadmium battery and the nickel metal-hydride battery. That makes it useful for devices that should be lightweight. Lithium-ion batteries work by the movement of lithium ions through a membrane. They are different from lithium batteries. Lithium batteries contain lithium metal and are not rechargeable. Lithium-ion batteries do not contain lithium metal and are rechargeable. They also do not last forever. Each lithium-ion battery will have an average of 600 charge cycles.

It is lighter than the nickel cadmium battery and the nickel metal-hydride battery. That makes it useful for devices that should be lightweight. Lithium-ion batteries work by the movement of lithium ions through a membrane (thin sheet that allows some substances to pass through). They are different from lithium batteries. Lithium batteries contain lithium metal and are not rechargeable (primary cells). Lithium-ion batteries do not contain lithium metal (only lithium compounds) and are rechargeable (secondary cells). They also do not last forever. Each lithium-ion battery will have an average of 600 charge cycles.
