Weakened Interfacial Hybridization Unlocks High‐Capacity Operation of Commercial Spinel Cathodes
Abstract
ABSTRACT Despite significant progress in cathode and electrolyte design, interfacial degradation continues to limit the practical capacity of high‐energy secondary batteries. Here, we introduce a thermodynamics‐guided strategy to modulate the interfacial hybridization by aligning the electronic band structures of the cathode and electrolyte. As a proof of concept, we construct a weakly hybridized inner Helmholtz plane (IHP) layer on commercial LiNi 0.5 Mn 1.5 O 4 (LNMO), and unlock an unprecedented practical specific capacity of 333.0 mA h g −1 and a specific energy of 1097.0 Wh kg −1 , far exceeding the conventional operational thresholds (
