Liquid metal battery

Abstract

The invention discloses a liquid metal battery. The liquid metal battery at least comprises a first component, wherein the first component comprises a first housing and a first conductive crucible arranged in the first housing; a first positive electrode, a first negative electrode and a first negative electrode lead-out rod are arranged in the first conductive crucible; one end of the first negative electrode lead-out rod is inserted into the first negative electrode; the first conductive crucible is filled with a first electrolytic material; a first top cover is arranged at the top of the first housing; an insulation part is arranged in the middle of the first top cover; the first negative electrode lead-out rod is vertically arranged; the other end of the first negative electrode lead-out rod penetrates out of the insulation part and is insulated with the insulation part. According to the liquid metal battery with the structure, the first conductive crucible with the insulation effect is arranged in the first housing and is used for preventing alloy reaction between the first positive electrode and the first housing; the first electrolytic material and the first positive electrode are arranged in the first conductive crucible; the liquid metal battery is relatively long in cycle life, few in the influences of the outside world and relatively convenient to manage.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a liquid metal battery. Background technique [0002] At present, due to the excessive exploitation and utilization of non-renewable energy such as petroleum, it has caused serious damage to the human living environment. , solar energy, etc. have strong and weak changes, causing their energy to be strong and sometimes weak, which greatly restricts their energy supply. Therefore, it is necessary to study the stability of the above-mentioned unstable energy. [0003] Through the research, it is found that the energy storage battery first stores the energy of unstable energy and then outputs it stably, which can greatly improve the stable transmission of energy, thereby reducing the impact of the above-mentioned new energy on the grid when it is connected to the grid for power generation. Therefore, it is particularly important to develop large-scale energy storage technology that can stor...

Problems solved by technology

[0005] However, there are still some defects in liquid metal batteries at present. For example, the battery needs to work at high temperature, and the positive and negative electrode materials and electrolyte molten salt inside the battery are all in liquid state. They are extremely sensitive to moisture and oxygen in the air, which is a major cause of battery failure. Reason, so battery sealing requirements are very high

In addition, at high temperature, the molten positive and negative electrodes and the molten salt corrode the battery components such as the casing and the positive and negative insulating ceramics at a faster rate, especially the alkali metal of the negative electrode corrodes the insulating ceramics particularly severely, which will greatly reduce the service life of the battery. Shorten etc.
