An organic
electrolyte battery that through inhibition of any oxidative
decomposition of organic
electrolyte under
high voltage, attains an enhancement of cycle characteristics and is further capable of attaining a realization of
high energy density. There is provided organic
electrolyte battery (10) comprising positive
electrode material (2) and negative
electrode material (4) and, interposed therebetween, organic electrolyte (6), wherein positive
electrode active material particles (8) as a constituent of the positive electrode have surfaces at least partially coated with attachment (12) with electronic conductance and
ionic conductance not easily oxidized even when supplied with
oxygen from the positive electrode active material. The above attachment (12) is composed of microparticles of inorganic
solid electrolyte with
ionic conductance (14) and microparticles of conductive material with electronic conductance (16). In a
polymer lithium secondary battery, the microparticles of inorganic
solid electrolyte consist of any one of
lithium-containing phosphates, silicates, borates, sulfates, aluminates, etc., or a mixture thereof.
