摘要
Today’s world is stressed by the ever-increasing demand for energy and the disastrous climate changes.New technologies that generate,convert,and store energy in a greener and more efficient way become increasingly critical in building a sustainable society.On this front,batteries,capacitors,fuel cells,and solar cells play the indispensable roles as the powers for applications,for example,electric vehicles shall mitigate our reliance on the depleting fossil fuels.It is crucial to invent new materials or technologies to improve the electrochemical performance of energy storage/conversion devices with higher energy,better power,longer cycle life,and better safety.One of the most important areas pertains to carbon-based materials.Researchers from different fields design carbon-based materials for low-cost energy devices with great portability and functionality.
