Recently, Professor Zhao Yang of the School of Chemistry and Chemical Engineering at Beijing Institute of Technology, in collaboration with Professor Qu Liangti's group and Dr. Wang Ying from Tsinghua University, released a research paper in the esteemed international chemistry journal ACS Nano. The paper, titled "Cascading Spatial Confinement Strategy for Achieving Ultra-High Energy and Power Densities in Planar Micro-Supercapacitors" (DOI: 10.1021/acsnano.6c02331), addresses the pressing need for compact, high-performance power sources in flexible and wearable electronics.

The study introduces a cascading spatial confinement strategy, which markedly boosts the energy and power densities of planar micro-supercapacitors (P-MSCs) by creating a three-dimensional interlocking architecture. Using zinc//activated carbon P-MSCs as a model system, the team demonstrated that this approach more than doubled the utilization efficiency of active materials, attaining an impressive energy density of 117.5 mWh cm⁻³ and a power density of 2382.0 mW cm⁻³. This strategy proves adaptable across various P-MSC configurations, offering an optimal power solution for the next generation of highly integrated, wearable electronic gadgets. The research received backing from initiatives such as the National Key Research and Development Program and the National Natural Science Foundation of China.
