Lithium ion batteries are known for their high energy density but so does the Li-polymer battery that even allows a slight increase. Solid polymer is flexible which makes it possible to create batteries into various shapes and sizes including thin films. It is common to find lithium polymer batteries that are relatively thin like the one used by Nokia BP-4L in several devices. Li-polymer batteries can be made very slim like a credit card that can fit neatly into stylish mobile devices so that they can be made lighter and extremely thinner than their counterparts to attract a lot of attention in the competitive market of mobile devices.

The charge and discharge characteristics of lithium ion batteries and lithium polymer batteries are the same and do not require a special charger. Safety issues are also alike since both require protection circuits. However, gas buildup when charging a Lithium polymer battery
