Li‐Ion Battery Anodes Combining Intercalation and Plating Energy Storage Mechanisms through SiOx/C Coated Graphite

open access: yesAdvanced Functional Materials, EarlyView.
A thin SiOx/C coating enables graphite to stably support Li intercalation and Li plating in a hybrid anode. Paired with an optimized localized high‐concentration electrolyte, the full cell achieves 584 mAh g−1 and 86% capacity retention after 500 cycles, highlighting a practical route toward higher‐energy lithium‐ion batteries.

General Synthesis of Amorphous Pd‐Based Nanoparticles Towards Highly Efficient Nitrate‐to‐Ammonia Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
A family of amorphous palladium‐based multi‐component phosphides nanoparticles, synthesized via a robust one‐step wet‐chemical method, overcoming the immiscibility of different elements and the difficulty in forming a stable, disordered structure. When applied in the electrochemical nitrate reduction reaction, these nanocatalysts effectively suppress ...

Measurement of heat release rate using regression of chemiluminescence signals in premixed ammonia-methane/hydrogen-air flames

open access: yesApplications in Energy and Combustion Science
This paper proposes a non-intrusive method for quantitatively measuring heat release rate (HRR) through regression of chemiluminescence signals. The method is demonstrated using premixed ammonia-methane-air and ammonia-hydrogen-air counterflow twin ...
