Problems solved by technology

However, under actual conditions, the lithium-air battery reaction cannot be carried out completely, and lithium peroxide will be produced during the reaction process, wasting a large part of the available energy.
In addition, the oxides generated by the reaction are easy to block the gas electrode, which makes the reaction process interrupted and cannot take advantage of its large energy density.
At the same time, due to the very high polarization overpotential of the air electrode, on the one hand, it limits the reaction kinetics, and on the other hand, it causes a lot of energy waste, which greatly reduces the advantage of large energy density of lithium-air batteries, making it difficult to increase the power density.

Abstract

The invention discloses a metal-water-air battery. The metal-water-air battery comprises a diaphragm; a metal cavity and a water electrode cavity which are respectively arranged on the two sides of the diaphragm respectively and form a closed space, wherein water is contained in the water electrode cavity; a metal negative electrode and a water electrode which are correspondingly arranged in the metal cavity and the water electrode cavity and respectively cling to the diaphragm; a hydrogen storage device which is connected with the water electrode cavity through a first pipe; and a fuel cell which is connected with the hydrogen storage device through a second pipe. Compared with the prior art, the metal-water-air battery is high in energy density, long in endurance mileage, convenient to store and transport and capable of being charged quickly.

Description

technical field [0001] The invention belongs to the battery field, and more specifically, the invention relates to a metal-water-air battery. Background technique [0002] The energy density of metal-air batteries, especially lithium-air batteries, is much higher than that of current lithium-ion batteries, which is completely comparable to the oil-gas system of internal combustion engines. Considering that the energy efficiency of batteries is much higher than that of internal combustion engines, lithium-air batteries The cruising range of an air battery car can theoretically far exceed that of a traditional car. However, under actual conditions, the lithium-air battery reaction cannot be carried out completely, and lithium peroxide will be produced during the reaction process, wasting a large part of the available energy. In addition, the oxides generated by the reaction are easy to block the gas electrode, so that the reaction process is forced to be interrupted, and the ...
