Crayfish shells can prepare high-performance electrode materials

Professor Zhu Xifeng's team at the University of Science and Technology of China (USTC) recently proposed a new method to prepare high-performance supercapacitor electrode materials from heavy bio-oil obtained by pyrolysis of agricultural and forestry waste and crayfish shells from food waste through a simple synthesis.

It is understood that the CSU research team has successfully synthesized hierarchical porous carbon with ultra-high specific surface area, high pore capacity and suitable oxygen atom content from heavy bio-oil using a biotemplate-alkali activation method with crayfish shells as auxiliary material. 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 layered porous carbon exhibited wide operating voltage and high energy density in the performance test of assembled supercapacitors, which has obvious performance advantages over existing electrode materials and is expected to be used in many applications including electric vehicles.

Recently, the results were published in the internationally recognized academic journal Carbon.
