Research Status of Lithium Oxygen Battery and Its Components

Abstract

Before the large-scale use of electric energy, fossil energy has been the main energy supply. The phenomenon of pollution and lack of supply caused by excessive consumption of fossil energy is becoming increasingly obvious. With the continuous consumption of fossil energy, electric energy is regarded as the replacement object of fossil energy. The task of storing electricity requires the support of batteries. In recent years, the battery industry has developed rapidly, including a battery with a high energy density. One of the materials needed for the reaction can be directly obtained from the air; This is a lithium-oxygen (Li-O2) battery. Since its invention, the battery has opened a new way of energy storage for people. This paper will briefly introduce the design concept, reaction principle, selection, and improvement of each part of the Li-O2 battery including anode, cathode and electrolyte. This paper provides a basic understanding of lithium oxygen battery.
