Liquid metal battery and KW-scale module of liquid metal battery

Abstract

The invention provides a liquid metal battery and a KW-scale module of the liquid metal battery. The positive electrode and the negative electrode of the liquid metal battery are led out from the side wall of a battery shell; the KW-scale module is formed by a plurality of battery modules through serial connection, the battery module is composed of an inner core of the battery module and a heat preservation layer wrapping the outside of the inner core of the battery module, the inner core of the battery module is composed of a heating partition plate and a plurality of liquid metal batteries used as repeating units and stacked on the heating partition plate, and all the liquid metal batteries in the inner core of the battery module are serially connected sequentially. The battery structure facilitates single-layer battery connection, the connecting distance among the batteries can be shortened to the maximum extent, the space is saved, the connecting resistance among the batteries can be reduced to be minimum, the energy loss inside the battery module can be reduced to the maximum extent, and the energy conversion efficiency of the battery module is improved. The design blank of the KW-scale module of the liquid metal battery is filled, and the commercialized process of the liquid metal battery can be promoted greatly.

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...
