Spatial Structural Self‐Regulation Engineering Increases Close Pores of Starch‐Derived Hard Carbon for Sodium‐Ion Batteries

open access: yesCarbon Energy, EarlyView.
Spatial structural self‐regulation strategy stimulates the conversion of the hydroxy group (–OH) in starch into carbonyl (–C=O) within a stable three‐dimensional cross‐linking structure. This structure not only reduces the production of water and volatile products, thereby preventing foaming during pyrolysis and improving carbon yield, but also ...

Insights Into the Effect of Humic Acids Extraction From Coal on Hard Carbon Microstructure and Sodium Storage Properties

open access: yesCarbon Energy, EarlyView.
This study employs a simple solid‐phase alkali‐oxygen oxidation (SAO) method to extract inherent components (humic acids) from coal. We successfully extracted yellow, brown, and black humic acids by adjusting the amount of alkali. Among them, brown humic acid extraction created abundant ultra‐micropores and closed pores, greatly enhancing sodium ...
