Superstructure Reconstruction Stabilizes Anionic Redox in Cobalt‐Free Lithium‐Rich Layered Cathodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Superstructure reconstruction through Ni3+‐induced Ni/Mn exchange stabilizes the anionic redox in cobalt‐free lithium‐rich cathodes. This strategy mitigates oxygen loss and transition metal migration, yielding high capacity (231 mAh g−1) and durable cycling (84% over 500 cycles) with suppressed voltage decay. Structural degradation in Li‐rich manganese‐

Bridging Policy Gaps in Transition Times: How Local Actors Navigate Low Policy Coherence for Advancing a Circular Built Environment

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT The construction sector is a major contributor to the climate crisis, accounting for over one‐third of global energy‐related CO2 emissions. In response, the European Commission identified the circular economy as a means of achieving green growth and prioritized the construction sector in its Circular Economy Action Plan.
