Non-aqueous electrolyte cell and solid electrolyte cell

摘要

A cell which is not deteriorated in cell characteristics and which maintains a cell shape encapsulated in a laminate film even when overdischarged to a cell voltage of 0V. The cell includes a cathode (2) containing a compound having the formula LixFe1-yMyPO4, 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 ≤ x ≤ 1.2 and 0 ≤ y ≤ 0.8, an anode (3) and a solid electrolyte (4). A cell member comprised of the cathode and the anode, layered together with the interposition of a solid electrolyte, is encapsulated in a laminate film (6).
