To get synthesis of nickel cobalt manganese ternary precursor,we make use of single factor experiment method by NaOH as precipitant and ammonia solution to have pH adjusted in agent and buffering agent with pH value of 11.5,the stirring speed of 800 r/min.A constant flow pump can control salt solution,NaOH solution and ammonia water.With temperature and salt concentration as a variable,we can get the best temperature 50℃ and salt concentration 1.0 mol /L.In order to test nickel cobalt manganese ternary precursor and lithium carbonate as raw material,we get manufacturer’s process conditions,synthesis of nickel and cobalt ternary manganese acid lithium materials with excellent performance,including discharge capacity of 156.687 mA·h /g with 1.0 C,and the capacity decay rate was 0.87% after 50 cycles and it can meet the requirements of power battery.
