▎ 摘　　要

NOVELTY - Lithium-boron electrode material, comprises lithium-boron alloy base and an anti-overflow layer attached to the surface of the lithium-boron alloy base, where the anti-overflow layer is made of nanometer material or a mixture of skeleton material and nano material. The nano material is zerodimensional nano material, one-dimensional nano material or two-dimensional nanometre material. The nano material is nickel powder, silver powder, iron powder, copper powder, gold powder, cobalt powder, carbon powder, silicon carbide powder, graphene, carbon nano tubes or carbon fibers. The skeleton material is carbon fiber, carbon nanotube, nano-silver wire, nano-gold wire, nano-nickel wire, nano-copper wire, nano-cobalt wire or nano-silicon carbide wire. USE - The material is useful in preparation of thermal battery, preferably Fe0.5Co0.5S2 as anode, lithium chloride-pottasium chloride as the electrolyte, and lithium boride electrode material as the cathode (all claimed). ADVANTAGE - The nano-material has large adsorption capacity and capillary action can realize the adhesion and plugging of the lithium-boron alloy surface, so as to inhibit the overflow of liquid metal lithium lithium lithium boron alloy under high temperature and complex mechanical condition. The lithium-boron electrode material ensures the safety of the heat battery development and manufacture of the wider temperature range, and improves the performance of heat battery environment adaptive capacity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of lithium-boron electrode material.
