摘要： The positive active material for a lithium secondary battery includes a lithium transition metal composite oxide having an α-NaFeO2 structure, and having a diffraction peak at 2 θ=44±1° and a diffraction peak at 2 θ=18.6±1° in a powder X-ray diffraction diagram using a CuKα ray. In a ratio FWHM (003)/FWHM (104) of a full width at half maximum FWHM (003) for the diffraction peak at 2 θ=18.6±1° to a full width at half maximum FWHM (104) for the diffraction peak at 20 θ=44±1°, a ratio of FWHM (003)/FWHM (104) in a charge state immediately after a discharge state to FWHM (003)/FWHM (104) in the discharge state is 0.72 or more.

摘要： Methods and apparatus to form biocompatible energization elements are described. In some examples, the methods and apparatus to form the biocompatible energization elements involve forming cavities comprising active cathode chemistry and depositing separators within a laminate structure of the battery. The active elements of the cathode and anode are sealed with a laminate stack of biocompatible material. In some examples, a field of use for the methods and apparatus may include any biocompatible device or product that requires energization elements.
