What can crayfish shell do? Experts use it to prepare high-performance electrode materials
Xinhua News Agency (Reporter Xu Haitao) The reporter learned from the University of Science and Technology of China that Professor Zhu Xifeng’s team recently proposed a new method that uses heavy bio-oil obtained from the pyrolysis of agricultural and forestry wastes and crayfish shells in kitchen waste. Simple synthesis can be prepared into high-performance supercapacitor electrode materials.
It is understood that the USTC research team used the biological template-alkali activation method and used crayfish shells as auxiliary materials to successfully synthesize layered porous carbon with ultra-high specific surface area, high pore volume and suitable oxygen atom content from heavy bio-oil.
At the same time, they also studied the effect of activation temperature on the content of layered porous carbon heteroatoms, and optimized the process conditions for obtaining high-performance supercapacitor electrode materials.
The layered porous carbon prepared in this way exhibits wide operating voltage and high energy density in the performance test of assembled supercapacitors. Compared with the existing electrode materials, it has obvious performance advantages and is expected to be used in electric vehicles including electric vehicles. Multiple application areas.
A few days ago, the internationally renowned academic journal "Carbon" published the results.
