Abstract

In recent years, the damaging effects of burning fossil fuels on the environment and petrol has started to decline, the demand for sustainable energy has risen sharply, and lithium electronic batteries have become a hot spot today due to their high specific capacity, high self-discharge rate, long life and high safety performance. Since lithium metal is an active metal, its preparation and preservation have high requirements on the environment. This paper discusses the development history, working principle, classification and practical application of lithium electronic batteries in real life. The two types of lithium batteries are called lithium metal batteries and lithium ion batteries, respectively. The battery of lithium electronic battery is composed of positive electrode, diaphragm, organic electrolyte, battery shell and negative electrode. Rechargeable battery is also called “lithium ion". Its working principle is to cycle lithium ion back and forth between positive and negative electrodes, and to add and reuse lithium ion alternately and continuously between positive and negative electrodes during charge and discharge. There are basically three categories of lithium-ion battery electrolyte: liquid, solid and molten salt. At present, lithium iron phosphate or frequently used nickel-manganese-cobalt ternary materials are employed as the cathode of standard goods., and negative electrode is mainly graphite and other carbon materials. A better study could result from a deeper understanding of lithium-ion batteries, providing a wealth of theoretical knowledge for in-depth research.
