"textContent": "This invention relates to an electrode active material, an electrode containing the active material, and an electricity storage device including the electrode. The electrode active material comprises a silicon-containing carbon-based composite material obtained by preparing a uniform phase comprising at least (A) a crosslinkable composition that includes a silicon-containing compound having a crosslinkable group, and (B) a liquid or melt that does not participate in the crosslinking reaction of the crosslinkable composition; then crosslinking the component (A), causing phase-separation from the component (B) for obtaining silicon-containing crosslinked particles or a dispersion wherein the silicon-containing crosslinked particles are dispersed in the component (B); and then baking the silicon-containing crosslinked particles or the dispersion in an inert gas or in a vacuum at 300 to 1,500°C. The electrode active material is particularly suitable as an electrode of a lithium secondary battery, displays high reversible capacity and stable charge and discharge cycle characteristics, and is characterized by having little electrical potential loss when lithium is discharged.",
