Abstract

The invention discloses a structure and a method of a lithium slurry battery storage tank system, and belongs to the field of large-scale energy storage. A traditional lithium slurry battery system with two storage tanks is employed, wherein a positive electrode slurry tank and a negative electrode slurry tank are adopted. Compared with a traditional slurry tank, the system has the advantages thatthe storage tank can rotate, so that slurry sedimentation is avoided; a movable interlayer is arranged to separate the slurry entering the storage tank from the slurry output from the storage tank from the anode / cathode. By means of the structure, concentration polarization, self-discharge and safety problems caused by the difference of the charge states of the slurry in the lithium slurry battery reactor and the storage tanks are reduced, so that the utilization rate of active substances and the charge-discharge capacity are improved, the operation effect of the four-storage-tank system is achieved, and the cost and occupied space of the 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...
