Abstract: Chemically and mechanically protective oxide film was formed on Mg alloys using micro-arc oxidation (MAO) methods. Further modification of the obtained MAO surfaces was made in various aspects and the processes thereof were described. Firstly, the protection is enhanced by forming super-hydrophobic surfaces, with water contact angle higher than 140°, attributed to hierarchical nano-micro structures. Secondly, the electrical property of the MAO surfaces is modified. A film with sheet resistance as low as 0.05 ?/sq is achieved by electro-less Ni deposition on MAO surfaces. Thirdly, black colors are achieved by the sol-gel process on MAO samples.

Abstract: The present invention is to provide a transparent/translucent Li-ion battery. The transparent/translucent Li-ion battery comprises an anode, a cathode, and an electrolyte. The anode comprises an electrode material holder with inner structures, a current collector, and an anode material. The current collector is formed along the wall of the inner structures of the electrode material holder, and the anode material is deposited on the current collector, and filled within the inner structures. The cathode is fabricated with the similar method as the anode by using a cathode material. The electrode material holder with the inner structures can be a patterned glass or quartz slice with concave parts, or an anodized aluminum oxide film with channels. The transparent/translucent Li-ion battery of the present invention provides high transparency and electrical storage capacity.
