　　Understand the production characteristics of lithium batteries

　　Lithium battery is a type of battery that uses lithium metal or lithium alloy as the positive/negative electrode material and a non-aqueous electrolyte solution. The advantages of lithium batteries, such as extremely low self discharge rate and steep discharge voltage, enable pacemakers implanted in the human body to operate for a long time without the need for recharging. Lithium batteries generally have a nominal voltage higher than 3.0 volts and are more suitable for integrated circuit power supply.

　　Manganese dioxide batteries are widely used in calculators, digital cameras, and watches. In order to develop better types of functions, people have studied various materials and produced unprecedented products. With the development of science and technology, lithium batteries have become mainstream. Lithium batteries can be roughly divided into two types: lithium metal batteries and lithium-ion batteries.

　　Lithium ion batteries can be charged, and their safety, specific capacity, self discharge rate, and cost-effectiveness are all superior to lithium-ion batteries. Due to the limitations of their own high-tech requirements, only a few companies in certain countries are producing this type of lithium metal battery. Working principle of lithium batteries: Lithium batteries generally use manganese dioxide as the positive electrode material, lithium metal or its alloy metal as the negative electrode material, and non-aqueous electrolyte solution.

　　Discharge reaction: Li MnO2=LiMnO2 Lithium ion battery: Lithium ion batteries generally use lithium alloy metal oxide as the positive electrode material, graphite as the negative electrode material, and non-aqueous electrolyte. The reaction on the charged positive electrode is LiCoO2=Li (1-x) CoO2 xLi xe - (electron).
