How to use lithium batteries with different cathode materials

At present, the most widely used lithium battery cathode material has the characteristics of high open circuit voltage, large specific energy, and long cycle life; the lithium batteries produced are mainly used in the field of communication digital batteries. Cobalt is expensive, and lithium cobalt oxide is more toxic. At present, technically, the capacity has almost reached its limit. Constrained by resources, there is a tendency to be replaced. Lithium nickel cobalt manganese oxide (ternary): high electrochemical capacity, good cycle function, low cost, and ternary synergistic effect; it is mainly used in the field of lithium batteries with relatively low cost of communication digital products. The current production technology is relatively sophisticated. Lithium manganate: The research has been relatively sophisticated, low cost, no pollution, simple preparation, good safety function, low theoretical capacity, poor circulation function, restricted by the trend of battery miniaturization, mainly used for power lithium ion battery, low cost Battery field. Lithium iron phosphate: one of the most potential lithium battery cathode materials, with relatively high theoretical capacity, low price, good thermal stability, no pollution, and excellent charge and discharge cycle functions. At present, only a few manufacturers grasp the preparation technology; it is mainly used in the field of power lithium-ion batteries. Due to poor electrical conductivity, other materials need to be mixed, the tap density is low, and the specific capacity is relatively small. In the field of small batteries, batteries of the same size only need less than half of the existing battery capacity. The craftsmanship is extremely special and the production is difficult. The research and development of supporting electrolyte is slightly behind. The process requirements are extremely strict, because the power lithium-ion battery is generally composed of multiple batteries in series, so the consistency of a single battery is extremely high. Lithium nickelate: It is difficult to synthesize, and the amount is very small at present. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
