Abstract: A cell in which liquid leakage or destruction may be prevented as the apparent energy density per unit volume of the cell is maintained. The cell uses, as a cathode active material (2), a compound of an olivinic crystal structure having the formula LixFe1- yMyPO4, where M is at least one selected from the group of Mn, Cr, Co, Cu, Ni, V, Mo, Ti, Zn, Al, Ga, Mg, B and Nb and 0.05 ≤ x ≤ 1.2 and 0 ≤ y ≤ 0.8. By adjusting the amount of the electrolyte solution, the amount of the void in the container is set so as to be not less than 0.14 cc and not more than 3.3 cc per 1 Ah of the cell capacity.

Abstract: A non-aqueous electrolyte secondary cell containing a compound of an olivin ic structure as a cathode active material is to be improved in load characteristics and cell capacity. To this end, there is provided a non-aqueous electrolyse secondary cell including a cathode having a layer of a cathode active material containing a compound represented by the general formula Li x Fe 1-y M y PO4, where M is at least one selected from the group consisting of Mn, Cr, Co, Cu, Ni, V, Mo; Ti, Zn, Al, Ga; Mg, B and Nb, with 0.05 .ltoreq. x .ltoreq. 1.2 and 0 .ltoreq. y .ltoreq. 0.8, an anod e having a layer of a cathode active material containing the anode active material and a non-aqueous electrolyte, wherein the layer of the cathode active material has a film thickness in a range fro m 25 to 110 .mu.m. If a layer of a cathode active material is provided on each surface o f a cathode current collector, the sum of the film thicknesses of the layers of the cathode active material ranges between 50 and 220 .mu.m. The non-aqueous electrolyte may be a liquid-based electrolyte or a polymer electrolyte.
