Molecular Design Strategies for High‐Voltage Organic Cathodes

open access: yesAdvanced Energy Materials, EarlyView.
This work proposes molecular engineering strategies for high‐voltage organic cathode materials for Li‐ion batteries: (1) increase Li‐O coordination number (CN), (2) achieve a greater increase in aromaticity upon reduction (∆Aromaticity), and (3) add an electron‐withdrawing group (EWG), through a combined experimental and computational study on reported

Spatially Coupled Cl2 Confinement and Activation at Curved Ni Single‐Atom Sites for Highly Reversible Li–Cl2 Batteries

open access: yesAngewandte Chemie, EarlyView.
A robust cathode featuring curvature‐engineered Ni single‐atoms anchored within hierarchical pores effectively confines Cl2 and accelerates Cl0/Cl−1 redox kinetics. This synergistic architecture unlocks the potential of Li‐Cl2 secondary batteries with an unprecedented 1×106 mAh g−1 cumulative capacity, all‐climate resilience (–40°C to + 70°C), and 7.65
