This article reviews recent progress in nano-/micro- composite electrodes with hierarchical three-dimensional mixed conducting networks for lithium-ion batteries. First, we describe the concept and advantages of the nano-/micro-composite structure with three-dimensional mixed conducting networks. Secondly, we present some examples in which this concept was successfully realized in the electrode design for Li batteries. It has been demonstrated that the storage performance can be significantly improved in such new nanostructure designs. This concept can also be extended to the electrode structure design in other electrochemical devices.
