The difference between Lithium-Ion Batteries And Lithium Polymer Battery:

A lithium-ion battery is a rechargeable battery in which lithium ions are moved from the negative (anode) to the positive (cathode) by discharge, and also from the cathode to the anode by control. Such ultra-thin lithium batteries are typical in mobile consumer electronics because of their large energy-to-weight ratio, lack of memory impact, and slow self-discharge even when not in use.

The three main functional elements of a lithium-ion battery are the anode, cathode and electrolyte, of which many different substances may be used. Polymer Li-ion batteries, polymer Li-ion batteries, or Li-ion batteries are rechargeable (secondary) batteries, usually consisting of several indistinguishable secondary batteries in parallel to improve discharge current capacity.
