【High-nickel or Medium-nickel High-voltage Ternary Material Technology Route?】The endurance capability of new energy vehicles is a crucial factor in their replacement of traditional fuel vehicles, and it is also the core to meet consumer demand and increase market penetration. As the power source of new energy vehicles, the performance of lithium batteries is largely determined by the cathode material, especially the energy density, which is jointly influenced by the material's capacity and voltage. There are two main ways to improve the energy density of cathode materials: increasing specific capacity and applying high voltage.
