12.1.5 lithiUM PolyMer
This is a lithium battery with a solid polymer electrolyte. It is constructed with a
lm of metallic lithium bonded to a thin layer of solid polymer electrolyte. The solid
polymer enhances the cell’s specic energy by acting as both the electrolyte and the
separator. Moreover, the metal in solid electrolyte reacts less than it does with a
liquid electrolyte. A few companies are developing the lithium polymer battery for
cars that may double the range compared to other batteries.
