The Origin of Improved Performance in Boron‐Alloyed Silicon Nanoparticle‐Based Anodes for Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Silicon‐boron alloy nanoparticles are incorporated into lithium‐ion batteries as the active anode material and enhance the battery cycle and calendar lifetime with improved interfacial chemical passivation. This passivation is afforded by the strong surface dipoles imparted on the particles from Lewis acidic surface boron.

Selective Electrochemical Reduction of CO2 to Metal Oxalates in Nonaqueous Solutions Using Trace Metal Pb on Carbon Supports Enhanced by a Tailored Microenvironment

open access: yesAdvanced Energy Materials, EarlyView.
Encapsulating trace lead (Pb) in carbon electrodes with a fluoropolymer tailors the microenvironment for carbon dioxide (CO2) reduction. This enhances efficiency and selectivity, offering a tunable approach to guide reaction pathways and improve product outcomes in electrochemical CO2 conversion.

Peroxide‐Driven Nitrogen Fixation Reactions for Energy Storage Applications

open access: yesAdvanced Energy Materials, EarlyView.
Sustainable ammonia synthesis from air as a hydrogen energy carrier and storage medium is demonstrated via an efficient dual‐step electrochemical approach at ultralow overpotential (−0.1 V vs. RHE). Atmospheric nitrogen is first oxidized to nitrate using in situ generated peroxide, then directly converts to ammonia on the same electrode, achieving ...

Degradation of NiMo Catalyst Under Intermittent Operation of Anion Exchange Membrane Water Electrolyzer and its Mitigation by Carbon Encapsulation

open access: yesAdvanced Energy Materials, EarlyView.
Herein, by employing a reference electrode, the durability of anion exchange membrane water electrolyzer (AEMWE) under intermittent condition is demonstrated to be governed by the stability of the cathode catalyst. By encapsulating NiMo catalyst with carbon shells, the oxidation‐induced irreversible transformation to inactive hydroxide is prevented ...
