Interconnected microporous and heteroatom containing bio‐carbon, derived from universal household waste i. e. cooked rice has been investigated as an anode material for lithium and sodium‐ion batteries. Cooked rice derived carbon (CRC), prepared by an economically viable carbonization process, bestowed with the presence of nitrogen atom due to the bacillus cereus bacteria is chemically activated with KOH at different temperatures such as 800, 850 and 900° C. Among the prepared samples, CRC‐900 anode delivers an exceptionally high progressive capacity of ≈1000 mAh g‐ 1 at 100 mA g −1 for 100 cycles and reasonable capacity of 169 mAh g −1 for 1000 cycles. Further, CRC‐900 anode demonstrates high rate performance by delivering 260 mAh g −1 at 2 A g −1 in LIBs and an acceptable capacity of 78 mAh g −1 in SIBs at 2 A g −1 condition. CRC is found to contain micro and meso‐porous structure along with high surface area (1899 m 2 g −1 ) to endorse its suitability to this extend as an anode for LIBs and SIBs. The study illustrates the exploitation of waste‐to‐wealth attempt with an ultimate aim of recommending CRC as a potential anode for energy storage applications on the basis of low cost, cheap, eco‐benign electrode obtained from biodegradable cooked rice.
