Over the last years, hard carbon (HC) has been the most promising anode material for sodium‐ion batteries due to its low voltage plateau, low cost and sustainability. In this study, three biomass wastes (spent coffee grounds, sunflower seed shells and rose stems) were investigated as potential materials for hard carbon preparation combining a two‐step method consisting on Hydrothermal Carbonization (HTC), to remove the inorganic impurities and increase the carbon content, and a subsequent pyrolysis process. The use of HTC as pretreatment prior to pyrolysis improves the specific capacity in all the materials compared to the ones directly pyrolyzed by more than 100% at high C‐rates. The obtained capacity ranging between 210 and 280 mAh g‐1 at C/15 is similar to the values reported in literature for biomass‐based hard carbons. Overall, HC obtained from sunflower seed shell performs better than that obtained from the other precursors with an Initial Coulombic Efficiency (ICE) of 76% and capacities of 120 mAh g‐1 during 1000 cycles at C with a high capacity retention of 86‐93%.

“…We have a wide range of sources that can transform waste into treasure. The ICE of RHHC reported by Wang et al is only 66%, which still leaves considerable room for improvement. − We can work on the lignin fraction, specific surface area, and structure of the rice husk. Planting hard carbon materials to a higher level will facilitate the commercialization of biomass hard carbon.…”

As an effective complement to lithium-ion batteries, sodium-ion batteries are mainly used in some low-energy-density power cells and large energy storage devices. Of the numerous anode materials for sodium-ion batteries, hard carbon is undoubtedly the most mature and currently the only commercially available anode material, but there is still a long way to go before large-scale commercialization. In order to reduce the source cost of cathode materials for sodium-ion batteries, we chose biomass materials as the precursor of hard carbon cathode materials for sodium-ion batteries. In this study, it is demonstrated that hard carbon can be classified into plant-and animal-derived hard carbon, and the corresponding preparation methods, structural properties, and electrochemical properties are analyzed and summarized. In this study, we also summarize several approaches reported in the literature to improve the electrochemical properties of materials. The objective is to provide a reference for improving the properties of hard carbon materials from biological sources and to facilitate large-scale commercialization of hard carbon anode materials with sodium ions.

“…SC electrodes show reversible discharge specific capacity of 283 mAh g −1 at 50 mA g −1 , and the corresponding Coulombic efficiency is calculated as 93.9% based on the initial discharge capacity and the following charge capacity. Meanwhile, the specific capacity of the SC electrodes remains 94 mAh g −1 even at the high current density of 5 A g −1 , indicating an excellent rate performance, which is conducive to achieving a higher power density [68][69][70][71][72][73][74]. The corresponding chargedischarge curves of the SC half-cell at different current densities are shown in figure S4(c).…”

Metal-ion capacitors, especially lithium-ion capacitors (LICs), are promising energy storage devices with much higher energy density than conventional electrochemical double-layer capacitors (EDLC). While compared with the EDLCs, the stable voltage window of the cathode in LICs is much narrower than that in EDLCs because of the different energy storage mechanisms, which restricts the energy density of LICs. In this work, the porous carbon (D-HAC) with an ultra-low oxygen element content of 0.973 wt.% is synthesized by heating the starch-based porous carbon (HAC) in the hydrogen-argon mixing atmosphere. The specific capacitance of D-HAC reaches up to 106.7 F g −1 at 50 mA g −1 . Owing to high specific capacitance of D-HAC, LIC constructed with D-HAC cathode and soft carbon anode can provide a high energy density of 123.5 Wh kg −1 . More importantly, the D-HAC//SC LIC shows excellent capacity retention of 96.77% after 10 000 cycles at a high rate of 50 C due to the stable electrochemical interface of D-HAC. This work provides a simple and efficient method to remove the unstable oxygen element of the porous carbon materials and shows a promising approach to develop advanced metal-ion capacitors with high energy density and long cycle life.
