A high-power annular energy storage battery

Abstract

A high-power ring-shaped energy storage battery, including several layers of ring-shaped walls made of solid electrolyte coaxially set together, the two ends of the ring-shaped wall are respectively fixed on the insulating circular base and the circular upper cover, all the ring-shaped walls Together with the circular base and the circular upper cover, several layers of airtight chambers are enclosed together. The adjacent airtight chambers are filled with positive electrode materials or negative electrode materials at intervals. When the battery is running, the positive and negative electrode materials are both in liquid state; The bottom of the body draws out the positive and negative current lead-out poles respectively and gathers them to form the positive and negative poles of the battery. The battery provided by the invention has a large electrochemical reaction area and a current flow area, has excellent electronic conductivity, can reach a sufficiently large current density, and ensures a sufficiently high charge and discharge rate and power, and has a simple structure and low cost. It is cheap, can determine size parameters according to different capacity requirements, is easy to expand in scale, and can meet different capacity and space requirements.

Description

technical field [0001] The invention belongs to the field of energy storage, and in particular relates to a high-power annular energy storage battery. Background technique [0002] With the rapid increase of my country's economic aggregate, the form of energy is becoming more and more severe. How to effectively utilize the existing energy production capacity has become an important content of energy structure adjustment. In the context of vigorously building a smart grid, it is imminent to improve power quality. As an important indicator of power quality, the stability of power grid frequency is related to all aspects of national production, and it also represents the adjustment ability of the power grid to resist load shocks. When there is a large load change, in order to stabilize the frequency of the grid, input to the grid or absorb a large amount of energy from the grid in the shortest time to offset the large load fluctuations, so that the frequency of the grid can be ...

Problems solved by technology

[0004] However, due to the limitation of its physical energy storage method, the energy storage capacity of flywheel energy storage is very small, and the energy loss cannot be ignored; due to the technical barriers of supercapacitors, the manufacturing cost is high

However, there is no relevant report on such a chemical reaction-based ultra-high-power energy storage battery.
