With the support of the National Natural Science Foundation of China and HIT’s Scientific Research Innovation Fund, young teacher Wang Bo from School of Chemistry Engineering has made new progress in electrochemistry hybrid energy storage field. Wang Bo presented a new strategy for constructing hierarchical porous structure “bicontinuous active channel (ion and electron)” hybrid energy storage materials. This research result was published in Advanced Energy Materials (impact factors: 15.23) and Energy and Environmental Science (impact factors: 25.43), which are both famous journals in Energy and Materials field.
At present, the Lithium-ion batteries (LIBs), lead acid battery, capacitor and other chemical power sources have been widely used. Their active materials of electrode usually adopt one single electrochemical energy storage material. The behaviors of these power sources are limited by the behavior of single active material. Based on the storing energy characteristics and limitations of different active materials, Wang Bo and his colleages successfully designed a series of hybrid energy storage materials, which could achieve the in situ composites of different active materials and be efficient and collaborative during the process of energy storage. Meanwhile, through a lot of theoretical researchs, they hafurther reveal the mechanism of electrochemical hybrid energy storage and provide important theoretical basis and research methods. This new result has widespread academic guiding meanings and application values. The C@LiFePO4/carbon nanotubes microsphere composite (C@LFP/CNTs) with hierarchical porous structure has superior electrochemical capacity. It could charging the battery to 90% within 200 seconds, which is expected to realize quick charge for its cathode materials of the electric vehicles.
