Abstract
A thermal storage battery is described. The thermal storage battery includes a battery core including a battery core shell made of stainless steel and a thermal storage material mixture included in the battery core shell, the thermal storage material mixture including a mixture of sand and graphite; a plurality of heating elements placed in the battery core, in which each heating element is surrounded by a respective protective tube; a plurality of wall thermal insulation layers, a lid thermal insulation layer, and a bottom thermal insulation layer that enclose the battery core; and at least one heat extraction pipe configured to collect heat from the battery core. The battery core, the plurality of heating elements, the plurality of wall thermal insulation layers, the lid thermal insulation layer, the bottom thermal insulation layer, and the at least one heating collection pipe are encased in a steel outer frame.
