My undergraduate major is applied chemistry and my major is point analysis. Dalian Institute of Chemical Technology has the best fuel cell and Changchun Institute of Chemical Technology has the best electrical analysis. In terms of battery industrialization, Central South University is in the south and Harbin Institute of Technology is in the north. The industrialization of lithium batteries in Central South University is well done, and many domestic enterprises that do well in lithium batteries are hatched by teachers of Central South University. Fudan's supercapacitors are well made, and Tsinghua's advanced batteries are well made. Lithium batteries are very popular now, but the profits have been greatly reduced. Supercapacitor is a promising new industry, and fuel cell is still a long way from industrialization. . .
