Abstract
Ruddlesden–Popper-type oxysulfides Ln2Ti2O5S2 (Ln = Y, Nd) exhibit reversible lithium insertion. Nd substitution induces switching from biphasic to monophasic reaction behaviour in the low-potential region, as revealed by operando X-ray diffraction. Systematic solid-solution studies identify lattice expansion as the key parameter that switches the reaction mechanism.
Visual Abstract
