Abstract

The invention discloses a structure of a negative current collector of a liquid metal battery and an assembly method of the structure. The structure comprises a current collector lever, a porous metalplate, a foam metal and a three-way gasket, wherein the current collector lever is connected with the porous metal plate; the foam metal is clamped and laminated between the porous metal plate and the three-way gasket; the three-way gasket is connected with the current collector lever by a conductor fastener. The structure has the advantages that the technical problem of the physical and chemicalstability of the liquid metal battery at normal temperature and high temperature is solved, the battery reaction rate and the current collection efficiency are optimized, the internal impedance of the battery is reduced, etc.

Description

technical field [0001] The invention belongs to the technical field of energy storage batteries, and relates to a liquid metal battery negative electrode current collector 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 di...
