Abstract: System and method for predicting the remaining useful life (RUL) of a rechargeable battery, such as a lithium-ion rechargeable battery. In a method, the capacity of the battery is determined based on at least changes of state of charge values estimated at a first and second time and a net charge flow of the battery and applying a particle filter to a capacity degradation formula using the determined capacity to form a capacity degradation model and determining the RUL using the capacity degradation model using a pre-defined end of service threshold. The system and method may be used to predict the RUL of a rechargeable battery in an implantable medical device.

Abstract: Separator and electrolyte composites include a porous self-supporting separator film between or adjacent one or two electrolyte films. The electrolyte films may contain a glyme or mixture of glymes, LiX salt and complexing agent, such as PEO. The porous self-supporting separator film may be used dry or wetted with a liquid electrolyte composition. Solid state batteries include the described separator and electrolyte composites in combination with an anode and a cathode.
