Abstract:
An object is to suppress electrochemical decomposition of an electrolyte solution and the like at a negative electrode in a lithium ion battery or a lithium ion capacitor; thus, irreversible capacity is reduced, cycle performance is improved, or operating temperature range is extended. A negative electrode for a power storage device including a negative electrode current collector, a negative electrode active material layer which is over the negative electrode current collector and includes a plurality of particles of a negative electrode active material, and a film covering pan of the negative electrode active material. The film has an insulating property and lithium ion conductivity.

Claim (Index 1):
A method for forming a battery, comprising the steps of:\n forming a dispersion solution by dispersing a particle of an active material in a solution including one of metal alkoxide and silicon alkoxide, a stabilizing agent, and a solvent; attaching a gel, formed by hydrolyzing and condensing the one of metal alkoxide and silicon alkoxide in the dispersion solution, on a surface of the particle of the active material; and forming an oxide film on the surface by performing heating treatment on the gel.
