Material for electrode of power storage device, power storage device, and electrical appliance

A material for an electrode of a power storage device comprising:

• a granular active material comprising a carbon atom;
• and
• a film having a net-like structure over the granular active material,
• wherein the net-like structure comprises a plurality of bonds between the carbon atom and a silicon atom through an oxygen atom, and
• wherein the film partly covers a surface of the granular active material so that the surface of the granular active material has a first region which is covered with the film, and a second region which is not covered with the film.
