What is Lithium-ion battery?
[[File:Li ion laptop battery.jpg|thumb|Lithium-ion battery for laptop]] {{distinguish|lithium battery}} A '''lithium-ion battery''' is a lightweight, high-power [[battery]] used in [[computers]] and [[mobile phone]]s. Li-ion batteries are made in several shapes, although a flat rectangle is most common. They are lighter than the [[nickel cadmium battery]] and the [[nickel metal-hydride battery]]. Li-ion batteries useful for devices that should be lightweight. They work by the movement of lithium [[ion]]s through a membrane (thin sheet that allows some substances to pass through). They are different from [[lithium battery|lithium batteries]].<ref>{{cite web|title=LiPo battery|url=http://www.pdbattery.com/lithium-polymer-battery.html|publisher=www.pdbattery.com|accessdate=11 April 2016}}</ref> Lithium batteries contain [[lithium]] metal and are not rechargeable ([[primary cell]]s).

They also do not last forever. Traditional lithium-ion batteries will have an average of 600 charge cycles. Some newer versions such as lithium iron [[phosphate]] and lithium titanate can last for 3000 cycles or more. == Safety issues == Lithium-ion batteries can be very dangerous. They can catch [[fire]] or [[Explosion|explode]] if they are punctured, overcharged, or [[Short circuit|short-circuited]], or if there is a manufacturing [[defect]]. In a multi-cell battery pack, the fire can spread from one cell to another, consuming the entire pack. The fire cannot be put out with a [[fire extinguisher]] or water. Flaming [[electrolyte]] can be ejected from the battery, setting fire to nearby combustible material. Many products have been [[Product re
