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.

Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] join figure 1 and figure 2 , the high-power annular energy storage battery provided by the present invention includes several layers of annular walls 2 coaxially sleeved together made of solid electrolyte, the bottom of the annular wall 2 is fixed on the circular base 3, and the top of the annular wall 2 is fixed On the circular upper cover 1 , the outermost annular wall 2 has the same diameter as the circular base 3 and the circular upper cover 1 . Under the premise of ensuring the supporting strength, the thickness of the annular wall 2 should be as small as possible, preferably 3-5mm. Both the circular base 3 and the circular upper cover 1 are made of insulating material. Adjacent two-layer annular wall 2 forms a circular airtight cavity with the circular base 3 and the circular upper cover 1, and the innermost annular wall 2 forms a cylindrical...

Abstract

The invention discloses a high-power annular energy storage battery. The high-power annular energy storage battery comprises several layers of annular walls which are coaxially sleeved together and made of solid electrolyte, the ends of the annular walls are fixed on an insulating round pedestal while the other ends are fixed on a round upper cover, all the annular walls, round pedestal and round upper cover jointly form several layers of closed cavities sleeved together, anode material and cathode material alternatively fill the spaces between adjacent closed cavities at intervals, and when the battery runs, both the anode material and cathode material are in the liquid state; anode current and cathode current are led from the bottoms of the closed cavities and respectively gathered to form an anode and a cathode of the battery. The high-power annular energy storage battery has large electro-chemical reaction area and current flow area and good electronic conductivity; the high-power annular energy storage battery is capable of providing a large enough current density to guarantee a high enough charging/discharging speed rate and power, and moreover, the high-power annular energy storage battery is simple in structure, low in cost, capable of confirming size parameters according to different capacity requirements, easy to expand scale and capable of meeting 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 ...
