Providing a silicon-containing material having a novel structure being distinct from the structure of conventional silicon oxide disproportionated to use. A silicon-containing material according to the present invention includes at least the following: a continuous phase including silicon with Si&#x2014;Si bond, and possessing a bubble-shaped skeleton being continuous three-dimensionally; and a dispersion phase including silicon with Si&#x2014;O bond, and involved in an area demarcated by said continuous phase to be in a dispersed state.

Silicon-containing material and secondary-battery active material including silicon-containing material

An electricity storage device includes an electrode assembly, a case, a safety valve, and a cover member. The case accommodates the electrode assembly. The safety valve is arranged in the case and opens to discharge gas out of the case when an inner pressure of the case exceeds a release pressure. The cover member is arranged in the case opposing the safety valve and includes a flow passage for the gas.
