Solid state battery development
The main objectives of the project were to develop a secondary lithium polymer electrolyte battery with improved cycling properties at lower temperatures than ca. 100 C and to design and construct prototype cells with capacities in the range 1 to 10 Ah. The polymer electrolyte concept was identified as the only viable route to an all-solid-state battery able to fulfil a majority of the requirements of a future battery technology. In particular, this battery can be mass produced by modern coating and laminating technologies, so that it provides high energy density combined with the possibility of high power due to the thin film concept. The laminate technology provides genuine design freedom in creating large area battery configurations. The difficulties in realising a bipolar configuration with liquid electrolyte based systems are eliminated by the use of a flexible and mechanically stable solid polymer electrolyte. Furthermore the lifetime of this battery can be similar to that of the device for which it is intended.
