Energy storage and conversion device

Abstract

The invention discloses an energy storage and conversion device, which comprises a shell, a diaphragm, a secondary battery anode, a secondary battery cathode, a fuel battery anode, a fuel battery cathode, alkaline electrolyte, an oxygen storage tank and a hydrogen storage tank. The shell consists of a holding space, the diaphragm is arranged in the holding space, the secondary battery anode and the secondary battery cathode are disposed in the holding space, the fuel battery anode and the fuel battery cathode are arranged in the holding space, the fuel battery anode is electrically connected with the secondary battery anode, the fuel battery cathode is electrically connected with the secondary battery cathode, the alkaline electrolyte is formed between the secondary battery anode and the secondary battery cathode, the oxygen storage tank is communicated with the holding space and supplies oxygen to an anode of a fuel battery, and the hydrogen storage tank is communicated with the holding space and supplies hydrogen to a cathode of the fuel battery. The energy storage and conversion device has functions of both the fuel battery and a secondary battery, is simple in structure and low in cost and solves the problem of overcharge.

Description

technical field [0001] The invention relates to the field of batteries, in particular to an energy storage and conversion device. Background technique [0002] At present, human beings are facing the dual challenges of resource estimation and living environment deterioration. To this end, countries around the world are working hard to develop new materials, promote new concepts of low-carbon life, and promote human society to shift from the current high-energy consumption and high-consumption life and production mode to energy-saving, recyclable and sustainable development. Specifically, vigorously promote the application of clean energy, such as the application of solar energy and wind energy in the field of power generation, and the use of hybrid electric vehicles or pure electric vehicles to replace traditional gasoline-powered vehicles. [0003] The application of clean energy and new vehicles is inseparable from medium and large energy storage batteries and power batte...

Problems solved by technology

Both have their own advantages and disadvantages. Compared with fuel cells, secondary batteries have higher power and lower energy density.

This integration method has the following disadvantages: the circuit is complicated, the cost is high, and when the secondary battery is overcharged, it is easy to cause gas inside the battery and the active material on the electrode to fall off, etc.
