Herein, we have evaluated the role of polarity and conductivity in preparing a series of ascharite/reduced graphene oxide (RGO) aerogels by dispersing strong polar ascharite nanowires of varying mass into the conductive RGO matrix. When severed as Li-S battery cathodes, the optimized S@ascharite...
The technology was developed by Dr. Lynden Archer - Dean of the School of Engineering at Cornell University and licensed by Cerebral. The novel aluminum battery design is over 3X more efficient than lithium, and said to be much safer (no fire risk), 10X faster charging and has no supply ...

Lithium metal can, in theory, significantly improve the energy density of cells when combined with classical insertion or conversion cathode materials as well; it is the best choice if we want to employ post lithium ion battery chemistry1,2. However, secondary lithium-metal batteries still suffer...
Graphene is the ideal material forblocking the release of oxygen into the electrolyte. Researchers demonstrated that if they wrapped very small particles of the lithium cobalt oxide cathode of a lithium battery in graphene, it prevents oxygen from escaping. ...
