Abstract
A 3-dimensional disk electrode structure was designed to further improve the capacity and reduce the weight in the anode of a Li-ion battery. The additives, such as binding and carbon based conducting materials, were removed. In particular, Cu foil was not used in this 3-dimensional disk electrode. All the specimens were fabricated using conventional ceramic process, which was appropriate for the scale-up in industry. In the 3-dimensional disk electrode, the Cu-CoO composite was selected and excellent capacity was observed.
