FIELD: electricity.
SUBSTANCE: invention offers active material for negative electrode used in electrical devices, mainly for an accumulator battery or a capacitor in power supply sources for automobiles; the active material includes alloy represented by the formula SixCyAlz. In the formula SixCyAlz x, y and z represent values of mass percent and meet the following conditions: x+y+z=100; 36≤x<100; 0<y<64; and 0<z<64.
EFFECT: active material for negative electrode used in electrical devices demonstrates balanced properties combining high cyclic properties with high input capacitance and high efficiency of charge/discharge.
