Intrinsic Planar Defects Govern Durability in Single-Crystal Ni-Rich Cathodes

Abstract Single-crystal Ni-rich layered oxides are promising cathodes for high energy-density lithium-ion batteries, yet their electrochemical stability remains unexpectedly difficult to reconcile with the anticipated benefits of a grain-boundary-free architecture. Here, we revea...

Decoupled Synthesis Pathway via Precursor Functionalization Stabilizes High‐Voltage Nickel‐Based Cathodes

ABSTRACT Nickel‐based layered cathodes are promising candidates for high‐performance, high‐energy lithium‐ion batteries, yet their high‐voltage application is jointly limited by synthesis‐inherited structural defects and an unstable lattice oxygen framework. Here, we show that bo...
