Lithium battery is a kind of battery which uses lithium metal or lithium alloy as positive/negative materials and uses 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 in 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 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 battery has become the mainstream. Lithium batteries can be roughly divided into two types: lithium metal batteries and lithium ion batteries.
The lithium-ion battery can be recharged, and its safety, specific capacity, self-discharge rate and cost performance are better than the lithium-ion battery. Due to the limitations of its own high-tech requirements, only a few countries' companies are producing this lithium metal battery. Operating principle of lithium battery: lithium battery generally uses manganese dioxide as the positive material, lithium metal or its alloy metal as the negative material and non-aqueous electrolyte solution.
Discharge reaction: Li MnO2=LiMnO2 lithium battery: lithium ion battery generally uses lithium alloy metal oxide as the positive material, graphite as the negative material, and non-aqueous electrolyte. The reaction on the charged positive electrode is LiCoO2=Li (1-x) CoO2 x Li xe - (electron).
