Abstract

The invention discloses a structure and a method of a lithium slurry battery material storage tank system, belonging to the field of large-scale energy storage. The present invention uses a traditional lithium slurry battery system with two storage tanks, namely a positive electrode slurry tank and a negative electrode slurry tank. Compared with the traditional slurry tank, the slurry tank of the present invention has a rotatable storage tank to avoid slurry settlement; and has a movable partition to allow positive / negative electrodes to enter the slurry of the storage tank and output the slurry of the storage tank Separate, reduce the concentration polarization, self-discharge and safety problems caused by the difference in charge state of the slurry in the lithium slurry battery reactor and the storage tank, improve the utilization rate of active materials and charge and discharge capacity, and realize four storage tanks The operating effect of the system is improved and the cost and space occupied by two storage tanks are saved.

Description

technical field [0001] The invention belongs to the field of large-scale energy storage, and relates to the structural design of a lithium slurry battery energy storage device, in particular to a rotatable lithium slurry battery storage tank system with a movable interlayer structure. Background technique [0002] With the development of renewable new energy such as wind energy and solar energy, large-scale energy storage can effectively solve the grid-connection problems caused by the instability and discontinuity of such energy sources, so the development of low-cost, high-safety large-scale energy storage batteries It can effectively promote the utilization and development of this kind of energy. Lithium-ion batteries have the advantages of high energy density and long cycle life, but their high manufacturing costs limit their application in the field of large-scale energy storage; liquid flow batteries have a structural design that is independent of power and capacity, a...
