Flexible Thin Film Solid State Lithium Ion Batteries
Batteries are electrochemical cells which store and supply electrical energy as a product of a chemical reaction. In their simplest conceptualization, batteries have two electrodes, one that supplies electrons by virtue of an oxidation process occurring at that electrode and a second one that consumes electrons by virtue of a reduction process occurring at that electrode. Thin film ion batteries, including those of the thin film solid state lithium ion type, can be prepared from various deposition techniques to fabricate anode, cathode, and electrolyte materials bonded together to form the battery, individual cells of which may typically be less than about 25 microns in thickness. Such techniques may typically include depositing thin films of such materials using vacuum deposition or other techniques that result in similar thin films, to produce the thin film batteries. Thin film batteries are often employed in applications in which space and weight may preferably be conserved and extremely long cycle life may be desired.
Scientists at the National Renewable Energy Laboratory (NREL) have created a novel way of arranging thin film battery structures, using flexible thin films on thin, flexible substrates. The structures allow stacking or rolling of thin film batteries in a way such that the storage density of such structures can rival bulk batteries while retaining the beneficial attributes of the thin film batteries (e.g., long cycle life).
