Abstract
A negative electrode for an electric device includes a silicon-containing alloy containing silicon and tin, a carbon cover layer including a carbon material and covering the silicon-containing alloy, and a negative electrode electric conducting additive. A ratio of an average particle diameter of the silicon-containing alloy to an average particle diameter of the carbon material is 240 or greater. The negative electrode for an electric device and an electric device using the negative electrode can improve cycle durability.
