A new class of electrode materials are being intensively investigated to achieve a low-cost Li+ secondary battery (LIB) with a high discharge rate. Here, we investigated the discharge rate in thin film electrodes of the Prussian blue analogues (Li,Na)(4y-2)M[Fe(CN)(6)](y)zH(2)O (M = Ni, Co, Mn, and Cd). Except for the Co compound, the capacities at 100C exceed 60% of those at 1 C. We further investigated the electronic and crystal structures of Prussian blue analogues against Li+ concentration (x). On the basis of these data, we will discuss the origin of the rapid Li+ intercalation. (C) 2012 The Japan Society of Applied Physics
