There are two types of "Lithium Polymer" batteries: > Originally, "lithium polymer" stood for a developing technology using a polymer electrolyte instead of the more common liquid electrolyte. > The second meaning appeared when some manufacturers started applying the "polymer" denomination to lithium-ion cells in pouch format. The first one (polymer bag around a lithium ion battery) is currently used in many devices, but the second (polymer electrolyte) is not commonly used and seems to be an active area of research. http://en.wikipedia.org/wiki/Lithium_polymer_battery http://en.wikipedia.org/wiki/Lithium_polymer_battery The (common) Lithium Polymer batteries are, according to the Wikipedia page, as safe (or unsafe) as Lithium Ion batteries.
