Problems solved by technology

Due to the fluctuation of the electrolyte level during the working process of the battery, the thickness of the electrolyte layer of the current liquid metal battery is relatively large, generally speaking, the thickness cannot be less than 5mm, which will inevitably cause excessive ohmic polarization, thus limiting the industrial development of the battery;
[0007] (2) The stability of the electrolyte-electrode interface needs to be further improved
Liquid energy storage batteries contain active molten salts, complex systems of molten metals, magazine elements, interface infiltration characteristics, charge and discharge process, temperature changes and other factors may cause interface stability to decrease

Abstract

The invention belongs to the technical field of energy storage batteries and particularly relates to a liquid energy storage battery monomer structure with floating body electrolytes. The battery monomer structure comprises a seal housing, a crucible base, a sleeve pipe, a positive and negative current collector, a negative metal electrode, a positive electrode, liquid electrolytes and solid electrolytes, and three layers of liquid are automatically layered due to density difference and immiscibility. All the electrodes in the battery monomer structure are in a liquid form except for solid electrolyte sheets, and the mounting operation is convenient; a battery monomer is not limited by capacity, required materials are all conventional materials, and the preparation cost of a battery is low; and the prepared battery has a special battery structure and electrode characteristics and is long in working life. Therefore, the battery monomer structure is very suitable for the field of energy storage.

Description

technical field [0001] The invention belongs to the technical field of energy storage batteries, in particular to a single structure of a floating body electrolyte liquid energy storage battery. Background technique [0002] Power generation, power transmission, power distribution, power storage, and power consumption are the five important links in the power industry chain, and large-scale and high-efficiency energy storage technology is a key core technology that is urgently needed but needs to be solved urgently. Intermittent, an important technology to improve the quality of renewable energy power generation and promote the popularization and application of renewable energy. [0003] Cost and lifetime are key indicators to measure whether a technology is suitable for application in the field of energy storage. It is generally believed that in order for a chemical battery to have the development value of large-scale energy storage, its production cost should be less than...
