Abstract

The invention provides a liquid metal battery and a kilowatt-level module of the liquid metal battery. The positive and negative electrodes of the liquid metal battery are led out from the side wall of the battery casing. The kilowatt-level module is composed of several battery modules connected in series in sequence. The battery module is composed of the inner core of the battery module and the insulation layer wrapped outside it. The liquid metal battery is composed of repeating units stacked and stacked, and all the liquid metal batteries in the inner core of the battery module are connected in series in sequence. The battery structure of the present invention is convenient for single-layer connection between batteries, greatly reduces the connection distance between batteries, saves space, can minimize the connection resistance between batteries, and greatly reduces the energy loss inside the battery module. Loss, improve the energy conversion efficiency of the battery module. The invention fills the gap in the design of kilowatt-level modules of liquid metal batteries, and can greatly promote the commercialization process of liquid metal batteries.

Description

technical field [0001] The invention belongs to the field of electrochemical energy storage batteries, and in particular relates to a liquid metal battery and a kilowatt-level module of the liquid metal battery. Background technique [0002] With the rapid development of my country's economy, traditional fossil energy is increasingly scarce, and the load on the ecological environment is also becoming heavier. The importance of the development of new energy industries has become increasingly prominent; while adjusting the energy structure and increasing energy The importance of yield utilization and quality is obvious. In recent years, my country's photovoltaic industry and wind power industry have developed extremely rapidly, especially the installed capacity of wind power has doubled year after year. However, the inherent intermittent, discontinuous and unstable characteristics of wind power, photovoltaic and other new energy The new energy industry has a huge installed capa...
