The interlayer space of the layered materials is not always the electrochemical active area for contributing to the pseudocapacitive process. To our knowledge, few efforts have been devoted to?investigating the?effect?of interlayer distance of layered double hydroxides (LDHs) on pseudocapacitors. Here, we obtained the CoAl–LDH with different interlayer distance
