A liquid metal battery anti-corrosion sealing structure and assembly method thereof

Abstract

The invention discloses a liquid metal battery anti-corrosion sealing structure and an assembly method thereof, comprising a liquid metal battery sealing electrode, a cover plate with a liquid sealing wall and a liquid sealing bowl holder; the liquid metal battery sealing electrode includes an electrode core , the electrode core is provided with an upper transition piece and a lower transition piece, and an insulating piece is arranged between the upper transition piece and the lower transition piece; Fluid connection; the cover plate with liquid seal wall is set on the upper transition piece, and the liquid seal wall extends downwards in the upper groove of the liquid seal bowl holder; the liquid seal bowl holder and the cover plate with liquid seal wall are filled with heat-cured Liquid salt. This structure solves the technical problems of anti-corrosion and sealing of the liquid metal battery working at room temperature and high temperature for a long time, optimizes the space utilization of the battery, and reduces the cost of battery preparation.

Description

technical field [0001] The invention belongs to the technical field of energy storage batteries, and relates to a liquid metal battery anti-corrosion sealing structure and an assembly method thereof. Background technique [0002] Liquid metal batteries are new secondary batteries for grid-scale energy storage applications. The negative electrode of the battery is generally a simple substance or alloy of alkali metal or alkaline earth metal, and the positive electrode is generally a transition metal simple substance, alloy, or other compound that can form an alloy with the negative electrode and have a certain potential difference with the negative electrode. The electrolyte is an inorganic salt corresponding to the negative electrode metal or a mixture thereof. When the battery is running, its metal electrodes and inorganic salt electrolyte melt into a liquid state at high temperature, and automatically stratify according to the difference in density. When discharging, the...

Problems solved by technology

[0004] At present, liquid metal batteries have not yet been industrialized; most of the existing patents do not involve the anti-corrosion sealing of the battery, and the existing anti-corrosion sealing structures have not yet achieved the industrialized preparation standards, most of which are due to the sealing It can’t have both insulation and insulation, and there are also structures that can achieve good sealing, but the structure is complex, the manufacturing cost and the space occupied are relatively large, which affects the space utilization of the battery
