Steric Hindrance Engineering to Modulate the Closed Pores Formation of Polymer‐Derived Hard Carbon for High‐Performance Sodium‐Ion Batteries

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 21, 2024

The closed pores play a critical role in improving the sodium storage capacity of hard carbon (HC) anode, however, their formation mechanism as well efficient modulation strategy at molecular level polymer-derived HCs is still lacking. In this work, steric hindrance effect has been proposed to create for first time through grafting aromatic rings within and between main chains precursor. experimental data theoretical calculation demonstrate that steric-hindrance from ring side group can increase backbone rigidity internal free volumes polymer precursor, which prevent over graphitization facilitate during carbonization process. As result, as-prepared HC anode exhibits remarkably enhanced discharge 340.3 mAh/g 0.1 C, improved rate performance (210.7 5 C) boosted cycling stability (86.4 % 1000 cycles 2 C). This work provides new insight into mechanisms via engineering, shed light on development high-performance sodium-ion batteries.

The strong metal-support interaction (SMSI) in supported metal catalysts represents a crucial factor the design of highly efficient heterogeneous catalysts. This can modify surface adsorption state, electronic structure, and coordination environment metal, altering interface structure catalyst. These changes serve to enhance catalyst's activity, stability, reaction selectivity. In recent years, multitude researchers have uncovered range novel SMSI types induction methods including oxidized (O-SMSI), adsorbent-mediated (A-SMSI), wet chemically induced (Wc-SMSI). Consequently, systematic critical review is desirable illuminate latest advancements deliberate its application within article provides characteristics various most methods. It concluded that significantly contributes enhancing catalyst selectivity, increasing catalytic activity.
