摘要： An improved cathode material for nonaqueous electrolyte lithium electrochemical cell is described. The preferred active material is null-phase silver vanadium oxide (Ag2V4O11) coated with a protective layer of a metal oxide, preferably null-phase SVO (Ag1.2V3O1.8). The SVO core provides high capacity and rate capability while the protective coating reduces reactivity of the active particles with electrolyte to improve the long-term stability of the cathode.

摘要： A thin battery is configured with improved durability of foil-like electrode terminals. The thin battery has an electricity-generating element housed inside a battery outer casing with a pair of electrodes of the electricity-generating element being connected to electrode terminals that extend out from the outer edges of the battery outer casing. The electrode terminals have a base portion located partially with the battery outer casing and a tip portion spaced from the battery outer casing with strength transition point being formed between the base portions and the tip portions. The strength transition points of the electrode terminals are positioned to the outside at some distance away from the outer edge of the battery outer casing.

摘要： A reverse configuration, lithium thin film battery (300) having a buried lithium anode layer (305) and process for making the same. The present invention is formed from a precursor composite structure (200) made by depositing electrolyte layer (204) onto substrate (201), followed by sequential depositions of cathode layer (203) and current collector (202) on the electrolyte layer. The precursor is subjected to an activation step, wherein a buried lithium anode layer (305) is formed via electroplating a lithium anode layer at the interface of substrate (201) and electrolyte film (204). The electroplating is accomplished by applying a current between anode current collector (201) and cathode current collector (202).
