Abstract

The invention relates to an environment protection and environment adjustable oxygen-metal battery. A sealable box body is constructed as an environment adjustment box and provided with a temperature controller and an atmosphere controller, a battery main body is arranged in the sealable box body and is the oxygen-metal battery formed by a metal anode, an inertia cathode and a corresponding electrolyte solution, and the environment adjustment box has the temperature and the partial pressure of oxygen, nitrogen and carbon dioxide therein adjusted through the temperature controller and the atmosphere controller so that the temperature and the partial pressure are stabilized at set values. The environmental-protection and environment-adjustable oxygen-metal battery can be widely applied for energy supplies to a vehicle, a field and a deep sea.

Description

technical field [0001] The invention relates to an oxygen-metal battery which consumes oxygen and metal, and has the characteristics of environmental protection and adjustable environment. The oxygen-metal batteries here comprise air batteries. Background technique [0002] The emergence of batteries has greatly facilitated the power supply for outdoor operations. People have successively developed batteries such as lead storage batteries, nickel-metal hydride storage batteries, lithium-ion batteries, polymer lithium batteries, and fuel cells. However, due to their more or less problems such as "low voltage, not suitable for excessive discharge, unfriendly environment, scarce raw materials, high price, high dependence on infrastructure, unsafe, and fewer cycles", although air batteries have overcome The above problems, but have problems such as severe polarization, seepage, self-discharge, unstable catalyst, and severe heat generation. Therefore, it is necessary to develop...
