PURPOSE:To provide a battery low in internal impedance, by packing mixing fluid, in which electrode active material, if necessary conductive material is dispersed in a solution composed of macromolecular material and its solvent, is packed in a battery cover can respectively; excluding the solvent to form an electrode layer; and pressing the electrode layer by request to adjust the density of the electrode layer. CONSTITUTION:Conductive macromolecule, etc., such as the oxide of the transition metals such as Mn, Co, Ni; a chalcogen compound; and polyacetylene is used as positive active material. Alkali metal, such as Li, Na, and k; Li; Al; Mg; and pitch coke, etc., are used as negative active material. The conductive assistant, such as a carbon black, etc., of 2-40%, is added to electrode active material for increasing electrical conductivety, is dissolved in methylpurolidone, etc., is packed in a flat type battery sheathing can, and a solvent is excluded to obtain the laminated body of positive and negative active material layers via an electrolyte and a separator. Then a battery can, to which a fibrous and/or porous collector is electrically and mechanically connected at a bottom part, is used to improve collecting efficiency. |
