Recently, Wang Bo, a young teacher at Harbin Institute of Technology School of Chemistry and Chemical Engineering, made new progress in the field of electrochemical hybrid energy storage. It only needs to charge for 200 seconds and the charging rate can reach 90%. With the support of the National Natural Science Foundation of China and the HIT Research Fund, Wang Bo proposed a strategy for building a "double continuous active channel" (ion-electron) mixed energy storage material with multi-level structure. The research results were published in the field of energy and materials Famous journals "advanced energy materials" and "energy and environmental science." It is understood that the currently widely used lithium-ion batteries, lead-acid batteries, capacitors and other chemical power supplies, electrode active material generally use a single electrochemical energy storage materials. The performance of these power supplies is limited by the performance of a single active material in the electrode, resulting in limited energy storage capacity. According to the energy storage characteristics of different active materials, Wang Bo successfully designed a series of hybrid energy storage materials to realize the high-efficiency synergy of in-situ compounding and energy storage of different active materials. The theoretical study further revealed that electrochemical hybrid storage The energy mechanism provides an important theoretical basis and research methods for the development of electrochemical hybrid energy storage. In accordance with the strategy synthesized lithium iron phosphate / carbon nanotubes and graphene multi-stage hybrid energy storage materials have excellent electrochemical properties, fast charging 200 seconds charging rate of 90%, is expected to be achieved as its cathode material for electric vehicles Fast charge.
