    摘要: As a positive electrode active material, a lithium transition metal complex oxide having a layered rock-salt structure containing lithium (Li) and containing magnesium atoms (Mg) substituted for part of lithium atoms (Li) is used. The lithium transition metal complex oxide is formed by chemical or electrochemical substitution of Mg atoms for part of Li atoms in LiCoO2, LiMnO2, LiFeO2, LiNiO2, or the like. A cell is prepared in which a negative electrode 2 and a positive electrode 1 including the lithium transition metal complex oxide (positive electrode active material) are disposed in a non-aqueous electrolyte 5 including a lithium salt, and part of Li in the lithium transition metal complex oxide is extracted by discharging the cell. Then, the electrolyte including Li is replaced with an electrolyte including Mg, and the cell is discharged, so that Mg atoms are substituted for the part of Li atoms in the lithium transition metal complex oxide.

    摘要: The positive electrode active material of a positive electrode includes a sodium-containing transition metal oxide (NaaLibMxO2±α). The M includes at least two of manganese (Mn), iron (Fe), cobalt (Co), and nickel (Ni). For a negative electrode, a sodium metal or a metal that forms an alloy with sodium is used. A non-aqueous electrolyte produced by dissolving an electrolytic salt (sodium salt) in a non-aqueous solvent is used. Examples of the non-aqueous solvent may include a cyclic carbonate, a chain carbonate, esters, cyclic ethers, chain ethers, nitrites, amides and a combination thereof.

    摘要: A rolled foil of surface roughened copper as thick as 26 μm for example having a surface formed into an irregular shape with copper precipitated thereon by an electrolytic method is prepared as a negative electrode collector. Tin (Sn) or germanium (Ge) is deposited on the rolled foil described above, so that a negative electrode active material layer is formed. Note that the deposited tin or germanium is amorphous. The arithmetic mean roughness Ra in the surface-roughened rolled foil described above is preferably not less than 0.1 μm nor more than 10 μm. A non-aqueous electrolyte is produced by adding sodium hexafluorophosphate as an electrolyte salt in a concentration of 1 mol/l to a non-aqueous solvent produced by mixing ethylene carbonate and diethyl carbonate in the ratio of 50:50 by volume.
