Manipulating selenium molecular configuration in N/O dual-doped porous carbon for high performance potassium-ion storage

Abstract Hard carbon is the most attractive anode material for electrochemical sodium/potassium-ion storage. The preparation of hard carbon spheres directly from the broad sources of biomass is of great interest but barely reported. Herein, we developed a simple two-step hydrothermal method to construct porous carbon microspheres directly from the original waste biomass of camellia shells. The porous carbon microspheres have high specific capacities of 250 mAh g−1 and 264.5 mAh g−1 at a current density of 100 mA g−1 for sodium-ion batteries and potassium-ion batteries, respectively. And it has excellent cycle stability for sodium ions and potassium ions outperforming most reported hard carbons, which is mainly attributed to the microporous structure and spherical morphology. The work paves a way to prepare porous hard carbon spheres directly from biomass for alkali metal-ion batteries.

Carbon-based material has been regarded as one of the most promising electrode materials for Potassium-ion batteries (PIBs). However, the battery performance based on reported porous carbon electrodes is still unsatisfactory, while the in-depth K-ion storage mechanism remains relatively ambiguous. Herein, we propose a facile “in situ template bubbling” method for synthesizing interlayer tuned hierarchically porous carbon with different metallic ions, which delivers superior K-ion storage performance, especially the rate capability (158.6 mAh g-1@10.0 A g-1) and high-rate cycling stability (82.8% capacity retention after 2000 cycles at 5.0 A g-1). The origin of the excellent rate performance is revealed by the deliberately designed consecutive CV measurements, Ex situ Raman tests, GITT and theoretical simulations. Considering the facile preparation strategy, superior electrochemical performance and insightful mechanism investigations, this work can provide fundamental understandings for high performance PIBs and related energy storage devices like sodium-ion batteries, aluminum-ion batteries, electrochemical capacitors and dual-ion batteries.
