Fig. 1. Schematic illustration of the different types of interphases between NMC811 cathode and a sulfide SSE.

Fig. 1

a Formation of thick SCL when uncoated NMC811 is in direct contact with a sulfide SSE; b reduced SCL with an oxide coating on NMC811; and c a gradient lithium oxide-oxy-thiophosphate interface tailoring a smooth transition from oxide-favored to sulfide-favored. d Schematic representation of an NMC811 primary particle (pink colour) with an ionic conductive and gradient Li3P1+xO4S4x coating (blue colour). SCL stands for space-charge layer and PS-LPO-NMC stands for gradient Li3P1+xO4S4x-coated NMC811.
