ABSTRACT

Sustainable electrochemical energy devices (EEDs) will replace conventional energy consumption platform based on fossil fuels and make up the clean and renewable energy sources that are restricted by the region, season, and periodicity. The typical high power and/or energy storage devices, including solar cells, fuel cells, rechargeable batteries, and supercapacitors have been proposed as the future power sources for electrochemical energy storage systems. In this chapter, we mainly focus on these EEDs and summarize their working principles to provide guidance for rational design in electrodes toward next-generation EEDs.
