Liquid metal battery module insulation box

Abstract

The invention provides a liquid metal battery module insulation box, comprising an outer wall layer, a composite insulation layer, a radiation-inhibitory reflecting layer and an insulation box inner chamber sequentially from outside to inside, wherein the composite insulation layer includes an inner mullite fiber insulation layer, a middle metal vacuum insulation layer and an outer mullite fiber insulation layer, or the composite insulation layer includes inner, middle and outer mullite fiber insulation layers; the radiation-inhibitory reflecting layer is a single-mirror-side stainless steel plate, and the mirror side is arranged inward; liquid metal battery modules are arranged in tiers in the insulation box inner chamber. The liquid metal battery module insulation box including the outer layer, the composite insulation layer, the radiation-inhibitory reflecting layer and the insulation box inner chamber sequentially from outside to inside is simple in structure and low in insulation power consumption, can be made larger in size and can meet the requirement for large size of liquid metal battery modules.

Description

technical field [0001] The invention relates to the field of electrochemical energy storage, in particular to a liquid metal battery module incubator. Background technique [0002] With the rapid development of my country's economy, energy issues have increasingly become a bottleneck restricting the sustainable development of my country's economy and society. Developing new energy sources such as wind energy and solar energy and improving energy use efficiency are effective ways to solve energy problems. However, wind energy and solar energy have the disadvantages of low stability, geographical and time domain limitations. The application of large-capacity energy storage system can adjust the peak of the power grid, load the peak and fill the valley, effectively enhance the operation stability of wind power generation and solar power generation systems, and improve the power quality. [0003] Liquid metal batteries are a new type of low-cost, high-efficiency, and long-life ...

Problems solved by technology

In the prior art, there are few incubators specifically for liquid metal batteries. For example, the design of an incubator used in a liquid metal battery and a liquid metal battery kilowatt-level module (application number: CN201410777993.3) relies on the battery pack for heating The temperature inside the box is maintained by its own Joule heat and the heating partitions between the battery packs in the box. The multi-layer heating partitions will take up too much space, greatly reducing the total energy efficiency of the battery module, and only using the battery itself Although the thickness of the thermal insulation layer is designed to reduce the thickness of the thermal insulation layer, it increases the power consumption of the heating partition, which is not conducive to energy saving and environmental protection.
