Enhancing Specific Energy and Cycling Stability of High‐Temperature Na‐ZnCl2 Batteries with Foam‐Based Electrodes

open access: yesAdvanced Energy Materials, EarlyView.
Replacing nickel with zinc in high‐temperature sodium‐zinc chloride (Na‐ZnCl₂) batteries makes them more cost‐effective and sustainable. Foam‐based Zn/NaCl electrodes enable substantially increased metal utilization compared to granule‐based electrodes (66% vs 30%).

Chemical and Structural Degradation of Single Crystalline High‐Nickel Cathode Materials During High‐Voltage Holds

open access: yesAdvanced Energy Materials, EarlyView.
The study explores degradation of high‐nickel NCM cathodes during prolonged high‐voltage holds, revealing a novel non‐linear increase in charge transfer resistance (RCT) due to an inhomogeneous, resistive surface reconstruction layer (SRL). Detailed analyses uncover the gradual growth and non‐uniformity of the SRL, which causes constriction effects ...

MXene‐Enhanced Metal–Organic Framework‐Derived CoP Nanocomposites as Highly Efficient Trifunctional Electrocatalysts for OER, HER, and ORR

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Ti3C2Tx MXene‐containing metal–organic framework‐derived CoP nanocomposite electrocatalysts are prepared by the phosphidation of in‐situ produced ZIF‐67/MXene precursor at various heat treatment temperatures. The as‐prepared CoP@C/MXene‐360 nanocomposite exhibits promising electrocatalytic performance as trifunctional catalyst toward oxygen evolution ...

The impact of the Russia–Ukraine war on stock prices, profits and perceptions in the food supply chain

open access: yesAgribusiness, EarlyView.
Abstract The Russian invasion of Ukraine in February 2022 had profound consequences for the global economy. As both countries are major commodity exporters, the food value chain was also affected. This study investigates the impact of the invasion on stock prices, profitability and sentiments of agribusinesses along the food supply chain by using an ...
