High energy density: positive pole is sodium manganate, energy density of battery product: 200Wh/kg-250Wh/kg
Low energy consumption: the production process is simple, and the energy consumption is half of that of lithium battery
Low cost: the production process cost is low and the material cost is low. The comprehensive cost is half of that of lithium battery. To sum up, its low-temperature performance, low cost safety performance, environmental protection and rate performance are far superior to lithium ion batteries
Cathode material
The cathode material is NaMnO2, which belongs to layered oxide with high energy density. Because of its good electrochemical performance, high theoretical capacity and low price; However, the layered oxide cathode materials have continuous stress during the charging and discharging process, which is easy to cause the collapse and amorphous of the active material structure, resulting in poor cycle stability of the materials. The defect of cycle life is improved by using cation substitution method
Negative electrode material
The anode material is hard carbon, and its electrochemical performance is improved by regulating and modifying the hard carbon structure, regulating the pore structure, controlling the defects and controlling the surface area of the material
