The Enhanced Electrochemical Performance of Lithium/Sulfur Battery with Protected Lithium Anode

The protection layer was introduced to the surface of the Li anode to enhance the charge/discharge performance of lithium/sulfur batteries. The Pt protection layer was formed by magnetron sputtering method. When the Li anode is coated with the protection layer, the unit cells with a liquid electrolyte showed an enhanced charge/discharge performance, resulting in an average discharge capacity of 750mAh/g during 90 cycles. All the charge/discharge tests were performed at room temperatures.
