The nickel cobalt manganese ternary battery material used as the positive electrode of the battery has higher safety compared to lithium cobalt oxide batteries. However, the platform is too low, and when used on mobile phones (the cut-off voltage of mobile phones is generally around 3.4V), there is a clear feeling of insufficient capacity. In some counterfeit mobile phones, ternary batteries are already used, especially batteries with higher capacity. The conventional positive electrode material for batteries is lithium cobalt oxide LiCoO2, while the ternary material is nickel cobalt manganese oxide lithium (NiCoMn) O2. The precursor product of the ternary composite positive electrode material is made of nickel salt, cobalt salt, and manganese salt as raw materials, and the proportion of nickel cobalt manganese inside can be adjusted according to actual needs. The capacity of lithium iron phosphate is low, which is not suitable for the pursuit of high capacity mobile phone batteries. Scope of application: Power batteries, small electric products with low cost, high capacity (> 150mAh/g), working voltage matching with existing electrolytes (4.1V), and good safety. The common proportion of nickel cobalt manganese is listed as 424 333 523 701515 1C grams. The sample test provided by Henan Thinking is 145 147 155 165, and the compaction used in the workshop is 3, The biggest obstacle to using ternary batteries in China is the so-called discharge platform. The old view holds that the time when 4.2V is placed at 3.6V is the working time of the phone. In fact, many phones only shut down at 3.3V or even 3.0V. Japan and South Korea do not have a platform. It is said that compared to lithium cobalt oxide, the energy density of ternary batteries needs to be improved. Japan mentioned that the compaction of ternary batteries is similar to that of lithium cobalt oxide in China, and there is still a gap If compaction is improved based on cost advantages and safety, the ternary system will replace lithium cobalt oxide
