Beyond lithium — the search for a better battery

By Leon Yao Comments are Off #lithium ion, alternative technologies, Graphene

As the world’s power needs grow, the search is on for better battery technology — not just to keep smartphones charged for longer, but to run electric cars and to store energy produced by solar and wind power. For the last 25 years, the lithium-ion battery, has held sway. Packing a large amount of energy into a relatively small space

Graphene sponge helps lithium sulphur batteries reach new potential

By Savannah Chen Comments are Off Graphene, lithium-sulphur battery

To meet the demands of an electric future, new battery technologies will be essential. One option is lithium sulphur batteries, which offer a theoretical energy density more than five times that of lithium ion batteries. Researchers at Chalmers University of Technology, Sweden, recently unveiled a promising breakthrough for this type of battery, using a catholyte with the help of a
