Abstract

The invention provides a low-temperature liquid and semi-liquid metal battery. The low-temperature liquid and semi-liquid metal battery comprises a negative electrode current collector, a shell, an insulating crucible, a negative electrode material, a positive electrode material and electrolyte, wherein the positive electrode material and the insulating crucible filled with the negative electrodematerial are placed at the bottom in the shell, the positive electrode material and the insulating crucible are covered with the electrolyte, the negative electrode current collector extends into thenegative electrode material through a central hole in the top of the shell, and an insulating sealing material is arranged at a contact part of the negative current collector and the central hole at the top of the shell. The low-temperature liquid and semi-liquid metal battery is advantaged in that melting points of the positive electrode material and the electrolyte are low, so the battery can operate at the relatively low working temperature, moreover, the positive electrode material and the negative electrode material of the battery do not contain active metal, have low requirements for corrosion resistance of an insulating material, and the low-temperature liquid and semi-liquid metal battery is simple in battery structure, high in safety and low in cost.

Description

Technical field [0001] The invention relates to the technical field of energy storage batteries, in particular to a low-temperature liquid and semi-liquid metal battery. Background technique [0002] Energy storage technology is one of the key technologies to eliminate the bottleneck of the large-scale development and utilization of renewable energy. This technology can improve the utilization efficiency of wind power and photovoltaic power generation. At the same time, it can also improve the contradiction between power supply and demand, smooth the peak-valley difference of the grid, and improve the efficiency of traditional power generation. And improve the security and stability of the power grid. Electrochemical energy storage has the characteristics of high energy density, fast response time, low maintenance cost, and flexible and convenient installation. It is one of the hot development directions of energy storage technology. At present, the main electrochemical energy s...
