The present invention generally relates to electrodes for use in lead-acid battery systems, batteries and electrical storage devices thereof, and methods for producing the electrodes, batteries and electrical storage devices. In particular, the electrodes comprise active battery material for a lead-acid storage battery, wherein the surface of the electrode is provided with a coating layer comprising a carbon mixture containing composite carbon particles, wherein each of the composite carbon particles comprises a particle of a first capacitor carbon material combined with particles of a second electrically conductive carbon material. The electrical storage devices and batteries comprising the electrodes are, for example, particularly suitable for use in hybrid electric vehicles requiring a repeated rapid charge/discharge operation in the PSOC, idling-stop system vehicles, and in industrial applications such as wind power generation, and photovoltaic power generation.

A nanosized particle has a first phase that is a simple substance or a solid solution of element A, which is Si, Sn, Al, Pb, Sb, Bi, Ge, In or Zn, and a second phase that is a compound of element D, which is Fe, Co, Ni, Ca, Sc, Ti, V, Cr, Mn, Sr, Y, Zr, Nb, Mo, Ru, Rh, Ba, lanthanoid elements (not including Ce and Pm), Hf, Ta, W or Ir, and element A, or a compound of element A and element M, which is Cu, Ag, or Au. The first phase and second phase are bound via an interface, and are exposed to the outer surface. The surface of the first phase other than the interface is approximately spherical. Furthermore, a lithium ion secondary battery includes the nanosized particle as an anode active material.

An object of the present invention is to provide a cathode active material which contains small-particle sized and low-crystalline lithium transition metal silicate and which undergoes charge-discharge reaction at room temperature. The cathode active material for a non-aqueous electrolyte secondary battery is characterized by containing a lithium transition metal silicate and exhibits diffraction peaks having half widths of 0.175 to 0.6, the peaks observed through powder X-ray diffractometry within a 2 range of 5 to 50.
