Hard carbons are currently the most widely used negative electrode materials in Na‐ion batteries. This is due to their promising electrochemical performance with capacities of 200–300 mAh g−1 and stable long‐term cycling. However, an abundant and cheap carbon source is necessary in order to comply with the low‐cost philosophy of Na‐ion technology. Many biological or waste materials have been used to synthesize hard carbons but the impact of the precursors on the final properties of the anode material is not fully understood. In this study the impact of the biomass source on the structural and electrochemical properties of hard carbons is unraveled by using different, representative types of biomass as examples. The systematic structural and electrochemical investigation of hard carbons derived from different sources—namely corncobs, peanut shells, and waste apples, which are representative of hemicellulose‐, lignin‐ and pectin‐rich biomass, respectively—enables understanding and interlinking of the structural and electrochemical properties.
What a waste! The impact of different biowaste sources on the structural properties and electrochemical performance of hard carbons is still unclear. By unravelling and interlinking the properties of hard carbons with respect to the composition and structure of the biomass waste from which they are derived, this gap can be closed.
