摘要： The present invention relates to a non-aqueous electrolyte secondary battery. The negative electrode of the present invention is characterized by its composite particles constructed in such a manner that at least part of the surrounding surface of nuclear particles containing at least one of tin, silicon and zinc as a constituent element, is coated with a solid solution or an intermetallic compound, which are composed of the element contained in the nuclear particles, and at least one other element except the elements contained in the nuclear particles selected from a group comprising group 2 elements, transition elements, group 12 elements, group 13 elements and group 14 elements except carbon of the Periodic Table. The electrolyte uses anion lithium salts of organic acid dissolved in organic solvent with high oxidation resistant characteristics. By adopting the above construction, a battery which generates only a small amount of gas during a high temperature storing can be obtained. Furthermore, the batteries enjoy high energy density and a lower reduction rate of discharge capacity when used repeatedly as well as high charge/discharge properties.

摘要： Electrode plates for a lead-acid battery have an active material layer using polyvinylidene fluoride as a binder formed on both sides of a substrate. The substrate is selected from the group consisting of a foil-like sheet made of pure lead or lead alloy and a polyester film that is lead-plated or covered with a conductive coating layer containing carbon powder, whose main ingredient is graphite as a conducting agent. The method of manufacturing provides a thin electrode plate that is suitable for use as a spirally-wound type of electrode plate. The resulting plates have excellent high-rate discharge characteristics and long cycle life. The electrode plates are manufactured in a high productivity process that uses neither pore-forming agents nor pore-forming processes.

摘要： A process for manufacturing lithium containing oxides represented by a formula LiNi.sub.x Co.sub.(1-x) O.sub.2, or a formula LiNi.sub.x Mn.sub.(1-x) O.sub.2, having almost single phase, through completely replacing a part of the Ni with Co or Mn. The single phase structure has the advantage that Li mobility in the crystal is high, the positive active materials having almost single phase show a large capacity and excellent cycle characteristics. According to the method, the positive active materials of lithium containing oxides are prepared by burning lithium compounds and composite hydroxides comprising Ni and Co, or Ni and Mn. The composite hydroxides are obtained through co-precipitation of nickel and cobalt hydroxides, or nickel and manganese hydroxides by adding caustic alkali aqueous solutions to mixed solutions containing nickel and cobalt salts or nickel and manganese salts.
