Prof. Wang Zhenyang’s research group from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences (CAS) has enhanced the energy storage capacity of graphene supercapacitors via solar heating. Related research results were published in the Journal of Materials Chemistry A.
In low temperature environments, the hindered diffusion of electrolyte ions seriously restricts the electrochemical performance of supercapacitors. Electrode materials with solar-thermal properties are expected to provide a new strategy to solve this problem. However, it …
