Analysis of cathode materials for ternary lithium batteries

Cathode material of ternary lithium battery The cathode material is one of the key materials that determine the performance of lithium batteries, and is also an important source of lithium ions in current commercial lithium batteries. Its performance and price have a greater impact on lithium batteries. 1. Nickel cake Nickel is a secondary group in active metals. Its important function is the volumetric energy density of new batteries, which is an important breakthrough for new mileage. However, excessive content will cause nickel ions to occupy the position of lithium ions. Resulting in a decrease in capacity. 2. Cobalt powder Cobalt is also an active metal in the subgroup, which can inhibit the mixing of cations, thereby improving the use of improving stability and prolonging the life of the battery. In addition, it also determines the charge and discharge speed and efficiency of the battery. However, an excessively high cobalt content will cause the actual capacity to decrease. 3. The purpose of aluminum or manganese or aluminum is to reduce material costs. After all, nickel and cobalt are very expensive rare metals, which can improve the safety and stability of lithium batteries.
