Description

technical field [0001] The invention relates to the application field of liquid metal, in particular to a liquid metal biomass battery. Background technique [0002] With the rapid development of today's world, accompanied by a large amount of energy consumption, the energy problem is becoming more and more serious. How to efficiently use the existing energy output under limited resources has become a hot issue that people pay attention to. As we all know, in the power system, the peak-shaving and valley-filling of electric energy, the efficient utilization of intermittent energy such as new energy and grid-connected power generation all require efficient energy storage technology as support. Large-capacity energy storage technologies are mainly divided into chemical energy storage (such as lithium-ion batteries, sodium-sulfur batteries, flow batteries, etc.), physical energy storage (such as pumped water energy storage, compressed air energy storage, flywheel energy storage...

AI Technical Summary

Problems solved by technology

Among them, lead-acid batteries have low energy density, slow charge and discharge speed, short cycle life, and great environmental pollution; sodium-sulfur batteries use β-alumina solid electrolytes, which have high manufacturing costs and poor thermal stability, and are prone to rupture. And lead to serious safety accidents; the current density of lithium-ion batteries is low and the manufacturing cost is high; liquid flow batteries are also facing technical problems of key materials such as electrolytes, electrode plates, especially ion-exchange membranes, and high energy storage prices. question
