A predoping method for a negative electrode active material to dope the negative electrode active material with lithium ions using an electrolyte solution that includes lithium ions. The electrolyte solution includes at least one type of additive having a reduction potential higher than a reduction potential of a solvent contained in the electrolyte solution.

Predoping method for negative electrode active material, manufacturing method for negative electrode, and manufacturing method for power storage device

A battery manufacturing method includes forming a unit cell having a positive electrode that is obtained by a positive electrode active material layer containing an electrolytic solution being disposed on a positive electrode current collector, a negative electrode that is obtained by a negative electrode active material layer containing an electrolytic solution being disposed on a negative electrode current collector, and a separator interposed between the positive electrode and the negative electrode. The battery manufacturing method further includes applying pressure to one unit cell or with two or more stacked unit cells from the stacking direction, and charging the one unit cell or the two or more stacked unit cells after applying of the pressure. The method is performed such that the positive electrode and the negative electrode are formed without an application film being subjected to a drying process performed through heating.

Battery manufacturing method

A predoping method for a negative electrode active material to dope the negative electrode active material with lithium ions. The predoping method for a negative electrode active material includes: a predoping process and a post-doping modification process. In the predoping process, the negative electrode active material is doped with lithium ions, to thereby reduce a potential of the negative electrode active material relative to lithium metal. In the post-doping modification process, after the predoping process, reaction is caused between a reactive compound that is reactive with lithium ions and lithium ions doped into the negative electrode active material, to thereby increase the potential of the negative electrode active material relative to lithium metal. The potential of the negative electrode active material relative to lithium metal is 0.8 V or more at completion of the post-doping modification process.

An electric power generating apparatus is provided with a fuel gas supply, an air supply source, an external reformer having a reformer section supplied with the fuel gas, a fuel cell stack, a heat exchanger section disposed to the external reformer, and an exhaust gas combusting section. The fuel cell stack has an electric power generating cell section, which is supplied with the fuel gas that results from the reformer section. The heat exchanger section achieves heat exchange between the air and the reformer section. The exhaust gas combusting section permits unburned fuel gas, which is supplied from the electric power generating cell section, and the air to be mixed and combusted to achieve heat exchange with respect to the fuel cell stack.
