Li-ion sulfur polymer battery shows high energy density as well as safety

Green Car Congress

A team from the University of Rome Sapienza has developed a rechargeable lithium-ion polymer battery based on the combination of a high capacity sulfur-carbon cathode, nanostructured Li x Sn-C anode and polysulfide-added PEO-based gel membrane. Batteries Li-Sulfur' Moreover, the addition of a dissolved polysulfide (i.e.

Graphene-sulfur composite as stable high energy capacity cathodes for Li-ion batteries

Green Car Congress

Schematic of the synthesis steps for a graphene-sulfur composite material, with a proposed schematic structure of the composite. Researchers at Stanford University led by Drs. Sulfur also possesses other advantages such as low cost and environmental benignity. Nano Letters Article ASAP doi: /10.1021/nl200658.
