Biowaste: Eco-Friendly and High Performance Supercapacitors for Elevated Temperature Applications Using Recycled Tea Leaves (Global Challenges 8/2017)

The cover picture shows a high‐performance supercapacitor device where carbon derived from waste tea leaves was used as an active material for energy storage. Tea leaves derived electrode showed high specific capacitance, energy and power density with almost 100% capacitance retention upto 5,000 cycles of study. This work provides a direct path for recycling bio‐waste for environment‐friendly, low‐cost, high‐performance and durable energy storage devices.
