摘要
Today' s world is stressed by the ever-increasing demandfor energy and the disastrous climate changes. Newtechnologies that generate, convert, and store energy ina greener and more efficient way become increasinglycritical in building a sustainable society. On this front,batteries, capacitors, fuel cells, and solar cells play theindispensable roles as the powers for applications, forexample, electric vehicles shall mitigate our reliance onthe depleting fossil fuels. It is crucial to invent newmaterials or technologies to improve the electrochemical performance of energy storage/conversion deviceswith higher energy, better power, longer cycle life, andbetter safety. One of the most important areas pertainsto carbon-based materials. Researchers from differentfields design carbon-based materials for low-cost energydevices with great portability and functionality.
