According to the statistics from Gaogong Industry Research Institute (GGII), the output of li-ion battery ternary material was 54.3 thousand tons, with 48.8% YoY growth in China 2016. The output value was RMB7.9 billion with over 60% YoY growth, which account for the largest proportion of output value amongst 4 cathode materials.  Compare to ternary material, the output of precursor is short; therefore precursor companies are planning to expand production capacity. According to the statistics from GGII, the average price of power 523 precursor was about 75k/ton; the gross profit was lower than 15%. The demands of ternary precursor exceeded 50k tons in China. GGII spent months in research on upstream and downstream companies, in order to collect primary data to finish <China Automatic Start/Stop Power Source Market Research 2017>.
