The cathode material products include various layered oxide materials, such as high power (HP), medium to high energy density (MH), and high energy (HE) materials. These materials utilize rich and widely distributed raw material resources, have low cost, and are environmentally friendly. Among them, HP materials exhibit excellent performance at low temperature, high-rate capability, and cycling performance, low residual alkali, and are easy to process. MH materials have high energy density, long cycling life, low residual alkali, and excellent processing performance. HE materials have ultra-high energy density, stable structure, outstanding cycling performance, good safety performance, and low residual alkali, etc.
