Description

technical field [0001] The invention relates to the field of thermal regeneration batteries, in particular to a non-aqueous thermal regeneration battery using a porous membrane. Background technique [0002] Thermally Regenerative Battery (TRB) is a new type of electrochemical power generation system technology that converts low-temperature waste heat into electrical energy. [0003] The non-aqueous TRB is based on an electrochemical reaction. By adding copper ions to the battery catholyte and adding nano-copper particles to the battery anolyte, a potential difference is formed to generate electrical energy. The whole cycle process of non-aqueous TRB includes power generation process and thermal regeneration process. In the process of electricity generation, the non-aqueous TRB cathode undergoes a reaction in which copper ions in the electrolyte are reduced to cuprous ions, and in the anode, the copper electrode is corroded by acetonitrile to form cuprous-acetonitrile compl...
