Professor Zhu Xifeng's team at the University of Science and Technology of China (USTC) recently proposed a new method to make high-performance supercapacitor electrode materials from heavy bio-oil obtained by pyrolysis of agricultural and forestry wastes and crayfish shells from food waste through a simple synthesis.
The research team successfully synthesized layered porous carbon with ultra-high specific surface area, high pore capacity and suitable oxygen atom content from heavy bio-oil using crayfish shells as auxiliary materials, according to Xinhua News Agency.
They also studied the effect of activation temperature on the heteroatom content of layered porous carbon, and optimized the process conditions for obtaining high-performance supercapacitor electrode materials.
The resulting prepared layered porous carbon exhibited a wide operating voltage and high energy density in performance tests of the assembled supercapacitor.
This provides significant performance advantages over existing electrode materials and is expected to be used in several applications including electric vehicles.
Crawfish is one of the most popular foods in China, and previous statistics showed that the total output value of China's crawfish industry reached 411 billion yuan in 2019, up 19.28% year-on-year.
Among them, the output value of the crawfish farming industry is about 71 billion yuan, the output value of the secondary industry, mainly the processing industry, is about 44 billion yuan, and the output value of the tertiary industry, mainly the catering industry, is about 296 billion yuan.
