Biomass-derived carbon materials prepared via pyrolysis from natural wood structures show potential for a storage application. Natural is composed of multiple sources, including lignin, hemicellulose, and cellulose, which influence the formation microstructure carbon. However, mechanism not fully understood. In this work, vast lignin selectively consumed biodegradation with fungi basswood. The results demonstrate that as-prepared material has short-range ordered graphitic structure after...
Abstract Rational design of porous conductive hosts with high electrical conductivity, large surface area, and adequate interior space is desirable to suppressing dendritic lithium growth accommodating volume change metal anode during the Li plating/stripping process. However, due nature hosts, easily deposited directly on top which hinders it from fully functioning. To circumvent issue, in this study, we designed a novel carbon host gradient‐pore‐size structure based one‐dimensional (1D)...
Polybenzoxazine is used as a novel carbon and nitrogen source for coating LiFePO4 to obtain LiFePO4@nitrogen-doped (LFP@NC) nanocomposites. The nitrogen-doped graphene-like that in situ coated on nanometer-sized particles can effectively enhance the electrical conductivity provide fast Li+ transport paths. When cathode material lithium-ion batteries, LFP@NC nanocomposite (88.4 wt % of LiFePO4) exhibits favorable rate performance stable cycling performance.
Hard carbon attracts great attention as an anode material for sodium‐ion batteries (SIBs), due to its high conductivity and environmental benignity. However, the practical applications of hard anodes are largely limited by poor cycling stability cost.

This special with moderate surface area exhibits long‐term (91.5% retention upon 800 cycles at 1000 mA g −1 ). Remarkably,...
Studying the law of coal adsorption capacity under action liquid nitrogen is very important for extraction coalbed methane. For this study, lignite's ability to adsorb methane was studied after it had been frozen by a number different freezing techniques. In addition, changes in organic functional groups on were identified using infrared spectroscopy. The results demonstrate that as duration and cycles increase, gas first decreases, then increases, finally maintains stable value. As time...
