Description

technical field [0001] The invention relates to the technical field of manufacturing an electrolyte thermoelectric battery, in particular to an electrolyte thermoelectric battery with a high-efficiency electrode structure and a preparation method for the electrolyte thermoelectric battery. Background technique [0002] The energy crisis has always been a major problem faced by countries all over the world. Due to the limited nature of non-renewable energy, people's demand for renewable energy and clean energy is unprecedentedly high. Using thermoelectric batteries to convert waste heat energy into electrical energy is one of the effective ways to solve the energy crisis. The electrolyte thermoelectric battery is different from the solid semiconductor thermoelectric battery. The electrolyte thermoelectric battery is a thermoelectric battery based on redox electrolyte pairs. Its working principle is to use redox electrolyte pairs to undergo different redox reactions under diff...
