Although Li insertion into the metal oxide anodes has relatively higher voltages than that of commercial anodes (graphite), they still offer great benefits such as low output voltages of Li-ion cell which is necessary for devices requiring low voltages. This application is particularly received great attention from electronic (optics and chips) industry. We will specifically discuss the Co and Mn-based metal oxides and their electrochemical performances in conjunction with their structural and morphological data. Anode active materials on different 3D structures, including Ni scaffold and corrosion resistance fibers, will be evaluated and discussed. Figure 1 shows the FESEM image of a direct conformal deposition of Co3O4 nanoflakes on corrosion resistance fibers. Our preliminary data revealed that this anode material can deliver up to 2000mAh/g capacities at relatively low rates. Rate capabilities will be evaluated using different 3D substrates.
