Using biomass-derived hard carbon materials as anode for sodium-ion batteries has facilitated resource recycling and brought significant economic benefits. However, the main obstacles to large-scale application of these are low Coulombic efficiency high irreversible capacity materials. This study used waste moso bamboo a source prepare pre-oxidize through stepped temperature sintering process. The introduction oxygen atoms into layers been shown increase spacing between layers, which facilitates insertion sodium-ions them. Moreover, presence oxygen-containing groups increases number edge vacancy defects in skeleton, thereby enhancing actual material. Studies have indicated that different pre-oxidation times varying impacts on electrochemical properties discarded raw material, optimal duration bamboo-based was determined be 4.5 h series comparative experiments. A high-performance material prepared via stepwise It exhibited specific 301.4 mAh·g−1 at 0.1 C first-cycle 87%.

Amorphous carbon, particularly hard carbon (HC), is widely considered as the most promising anode material for sodium-ion batteries (SIBs) due to its high reversible capacity and cost-effectiveness. However, complex poorly defined structural properties of HC present challenges in understanding underlying sodium storage mechanisms. To facilitate rational design high-performance anodes, a comprehensive correlation between microstructure behavior critical. This Review critically examines interplay features capabilities, focusing on two key factors: pore structure surface functional groups. It begins by outlining fundamental mechanisms HC, followed an in-depth discussion how chemistry influence storage. Finally, strategic insights are provided manipulate these factors optimize performance. aims drive development next-generation anodes support commercialization SIBs.

Coal-derived hard carbons (CHCs) have considerable potential as sodium storage materials because of their abundant resources and structural diversity. Nevertheless, the smaller layer spacing ordered carbon microstructure CHCs bring about low charge/discharge rates poor cycle life sodium-ion batteries (SIBs), rendering it challenging to support large-scale energy applications. Herein, preoxidation strategy is employed achieve multiscale structure optimization improve its capacity. The oxygen content in preoxidized coal reached 15.2%, contributing increasing cross-linked materials. Particularly, insertion Na+ facilitated by large 0.394 nm, well closed pores (0.162 cm3 g-1) improving diffusion Na+. Consequently, rate performance as-optimized anode (OCHC3) superior that directly carbonized. Specifically, OCHC3 exhibits a commendable (201 mAh achieves outstanding cycling stability (96.2%) over 500 cycles. Furthermore, galvanostatic intermittent titration reveals "adsorption-insertion-filling" OCHC3. This study enlightens rational design high-performance HC anodes for SIBs beyond.
