Covalent Organic Framework Bipolar Pseudocapacitive Electrodes in an All‐Organic Symmetric Lithium‐Ion Battery

open access: yesAdvanced Energy Materials, EarlyView.
Covalent organic frameworks (COFs) enable customizable redox properties for battery applications. A new bipolar WTTF‐COF, formed from p‐type W and TTF units via n‐type imine linkages, exhibits stable dual‐ion redox behavior and high capacity in Li‐ion cells.

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 ...

Toward Energy Justice Principles for Sustainable Lithium‐Ion Battery Technologies

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Prefeasibility life cycle assessment is used to evaluate the environmental, social, and supply chain impacts of lithium‐ion battery technologies, and the concept of distributional energy justice is discussed. By comparing chemistries and use cases, it reveals inequities in material sourcing and technology access.
