 This study has demonstrated the use of renewable pits from sorghum stalks as a material for potassium ion batteries. The material was found to have excellent performance with a high reversible capacity of 304.6 mAh G1 at 0.1 EG1 after 100 cycles and a stable cycling performance of 189.5 mAh G1 at 1 EG1 after 50 hundred cycles. Additionally, the material can be produced on a large scale in a short time frame, making it ideal for commercial applications.
