Porous carbon-sulfur for ultrahigh capacity lithium ion batteries

Stanford researchers have developed a nanostructured rechargeable battery consisting of a lithium sulfur based cathode and a silicon nanowire anode. The lithium sulfur is made electrochemically active by incorporating it within the pores of CMK-3 mesoporous carbon in the cathode. Silicon nanowire anodes provide high capacity, low reaction potential and moderate cycle life. This technology offers a safe, high energy density, light-weight battery.
