Lithium battery is a battery with lithium metal or lithium alloy as positive / negative material and non-aqueous electrolyte solution. The lithium battery has the advantages of extremely low self discharge rate and steep discharge voltage, so that the pacemaker implanted into the human body can operate for a long time without recharging. The nominal voltage of lithium battery is generally higher than 3.0V, which is more suitable for integrated circuit power supply.

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

 

Lithium ion battery can be charged, and its safety, specific capacity, self discharge rate and cost performance are better than lithium ion battery. Due to the limitation of its own high-tech requirements, only a few countries' companies are producing this lithium metal battery. Operating principle of lithium battery: manganese dioxide is generally used as the positive material, lithium metal or its alloy metal as the negative material and non-aqueous electrolyte solution.

 

Discharge reaction: LiMnO2 = LiMnO2 lithium battery: lithium ion batteries generally use lithium alloy metal oxide as positive material, graphite as negative material and non-aqueous electrolyte. The reaction on the charged positive electrode is LiCoO2 = Li (1-x) coo2 XLI XE - (electron).
