An electrode for an electricity storage device (10) of the present invention includes a porous layer (1) having either fibers or whiskers (1a) containing tungsten oxide. A valence band photoelectron spectrum of the fibers or whiskers (1a) obtained by an X-...

Orthosilicates containing the SiO4- tetranion as the building block are used as redox materials by incorporation of at least one transition elements with at least two valency levels. Lithium ingresses or egresses from the structure to compensate for the va...

An electrode material for an electrochemical device comprising a composite of a particulate conductive material and a metal oxide is prepared by mixing and dispersing the particulate conductive material with a colloidal solution of an oxide of an element i...
