1. Suppress battery polarization, reduce thermal effects, and improve rate performance; Lithium battery is a kind of primary battery with lithium metal or lithium alloy as cathode material and non-aqueous electrolyte solution. It is different from rechargeable lithium-ion battery and Lithium polymer battery. The inventor of lithium batteries was Edison. Due to the highly reactive chemical properties of lithium metal, the processing, preservation, and use of lithium metal have high environmental requirements. So, lithium batteries have not been applied for a long time. With the development of microelectronics technology at the end of the 20th century, there is an increasing number of miniaturized equipment, which has put forward high requirements for power supplies. Lithium batteries have subsequently entered a large-scale practical stage.
2. Reduce the internal resistance of the battery and significantly reduce the dynamic internal resistance increase during the cycling process; Lithium metal battery: The lithium metal battery generally uses Manganese dioxide as the cathode material, metal lithium or its alloy metal as the cathode material, and uses non-aqueous electrolyte solution.
Lithium ion batteries: Lithium ion batteries generally use lithium alloy metal oxides as cathode materials, graphite as cathode materials, and non-aqueous electrolytes.
3. Improve consistency and increase battery cycle life; Although lithium metal batteries have a high energy density, they can theoretically reach 3860 watts per kilogram. However, due to its unstable nature and inability to charge, it cannot be used as a power battery for repeated use. Lithium ion batteries, due to their ability to charge repeatedly, have been developed as the main power battery. However, due to the combination of different elements, the performance of the cathode materials composed of them varies greatly in various aspects, leading to increased disputes in the industry over the route of cathode materials.
