Abstract:
The method for manufacturing a particulate electrode active material provided by the present invention uses a carbon source supply material prepared by dissolving a carbon source (102) for forming a carbon coating film in a predetermined first solvent, and an electrode active material supply material prepared by dispersing a particulate electrode active material (104) in a second solvent that is compatible with the first solvent and is a poor solvent with respect to the carbon source. The carbon source supply material and the electrode active material supply material are mixed and a mixture of the electrode active material and the carbon source obtained after the mixing is calcined, thereby forming a conductive carbon film derived from the carbon source on the surface of the electrode active material.
Abstract:
A power storage device includes a fuel cell (33), a battery holder (1) and an end plate (40) for sandwiching and binding the fuel cell, and an interposed member (11) disposed between the end plate (40) and the fuel cell (33). The battery holder (1) and the end plate (40) are made of resin, and have a positive coefficient of thermal expansion at a temperature lower than a predetermined temperature. The interposed member (11) is formed to have a substantially negative coefficient of thermal expansion at a temperature lower than the predetermined temperature.
