Recently, under the guidance of Academician Fang Yining of Beijing Institute of Technology, the team Chen Haosen, Associate Professor Song Weili and other teams closely cooperated with Professor Jiao Shuqiang of Beijing University of Science and Technology, based on independent development of in-situ battery mechanics/electrochemical coupling visualization characterization technology, in dual ion battery mechanics / Significant progress has been made in electrochemical coupling, and relevant results are published in the international journal Advanced Energy Materials (impact factor 21.875 in 2017).
The work is based on rich mineral resources such as graphite and biomass. The ultra-light three-dimensional network carbon current collector is developed through biomass derivatives, and the graphite active material is loaded on the current collector to obtain a full carbon electrode. Integrated all-carbon dual-ion battery with positive and negative electrodes are all carbon electrodes. The realization of this full-carbon dual-ion battery provides a new idea for the development of low-cost, high-performance, electrochemically stable, mechanically stable dual-ion batteries. The value-added and efficient utilization of carbon resources has expanded a new direction, and proposed an alternative solution to alleviate the shortage of lithium resources and cobalt resources in traditional lithium-ion batteries.
