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

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 reveal intrinsic planar defects as a hidden structur...
