Lithium-metal-polymer batteries have been developed for a number of applications including electric vehicle propulsion systems and batteries to power telecommunications installations. Because there is no liquid or paste electrolyte, they are maintenance free. They have service lives as long as 10 years, under ambient temperatures from -40°C to +65°C.
One company that pioneered the devleopment of thin-film lithium-metal-polymer batteries has since been merged into the Bolloré Group in France. The former company was Avestor, Boucherville, Québec, Canada. one of their reprints is still available: Designing Lithium-Metal-Polymer Batteries for Safety
As announced by IPS Batteries a new thin-film construction for Lithium-metal-polymer batteries allows the batteries to be embedded in printed circuit boards or integrated circuit chips. The batteries are postage-stamp size and about 1/10 mm thick, and contain “micro-energy cells”.
The batteries demonstrate near zero self-discharge. The micro-energy cells are “ideally suited for use with all forms of energy harvesting techniques for recharging, such as solar, thermal, RF, magnetic and vibration energy.”
