Hydrogen and/or lithium insertion into hexagonal cesium tungsten bronze, Cs0.3WO3, was studied using voltammetric and a.c. admittance methods. The close values of stoichiometric coefficients for hydrogen and/or lithium in coinsertion bronzes as well as the close values of diffusion coefficients DH and DLi are ascribed to a lattice distortion caused by large cesium species which influence both equilibrium and the mobility of inserting species regardless of their different chemical nature.
