Researchers enhance the energy storage capacity of graphene supercapacitors via solar heating

Researchers from the Chinese Academy of Sciences (CAS), the University of Science and Technology of China and Tianjin University have enhanced the energy storage capacity of graphene supercapacitors via solar heating.

In low temperature environments, the hindered diffusion of electrolyte ions can restrict the electrochemical performance of supercapacitors. Electrode materials with solar-thermal properties are expected to provide a new strategy to solve this problem. However, it remains a challenge to develop electrode materials with both excellent solar-thermal properties and high energy storage capacity.
