Professor Kang Jianli of Tianjin Polytechnic University has led the research team to successfully synthesize a kind of new material with high potential and high energy storage. The capacitance is 2-3 times higher than the current supercapacitor, and the cost is low and the assembly is more convenient. This study uses aqueous electrolytes to be safer, more economical, and more environmentally friendly.
In addition to energy storage applications, the newly developed multivariate mixed oxide by Kang Jianli has also demonstrated excellent catalytic performance in the degradation of dye wastewater and the like, and this technology builds a three-dimensional porous composite structure (as shown) The advantages of membrane separation, the development of reaction - the separation of integrated functional metal membrane reactor can be widely used in wastewater treatment, organic synthesis and other fields.
Professor Kang Jianli proposed a new idea of ​​material design for multivariate mixed price wide potential coordinated energy storage. In cooperation with Professor Chen Mingwei of Northeastern University, a new method for preparing core / shell metal / oxide electrodes by metal polarization auto-oxidation , Successfully synthesized a wide potential energy storage of new materials. Using this electrode material to assemble supercapacitors, the overall energy density of the device will be 2-3 times that of current commercial supercapacitors. The material not only stores more energy, but also is made of cheap metal, which saves a lot of costs; the material is a block with a porous structure, which is not limited by the thickness of the motor when used and is more convenient to assemble. In addition, the material breakthrough in the international community for the first time the voltage limit of water electrolysis achieved in the water-based electrolyte (KOH) 1.8V wide potential stability, non-hydrolysis and other non-reversible side effects occur, more than 2300 cycles more than the capacitance of almost no change , Showing an ultra-stable structure.
