Abstract
Abstract A battery package for a thin battery includes a flexible base film that covers and encloses the battery and a flexible layer of an inorganic material such as silicon nitride, aluminum nitride or aluminum oxide deposited on the base film to encapsulate and seal the battery. The base film is formed of a flexible polymer material such as polyester that may be attached to the battery using a heat activated adhesive. The layer of inorganic material is deposited on the base film utilizing a low temperature CVD deposition process either before or after the base film is attached to the battery.
