Promising material for lithium-ion batteries

June 7, 2013 – 8:00 pm
  • Promising material for lithium-ion batteries - Laptops could work longer and electric cars could drive farther if it were possible to further increase the capacity of their lithium-ion batteries. The electrode material has a decisive influence on a battery's capacity. So far, the negative electrode typically consists of graphite, whose layers can store lithium atoms. Scientists have now developed a material made of boron and silicon that could smooth the way to systems with higher capacities.(10.1002/anie.201301540)

    All-solid sulfur-based battery outperforms lithium-ion technology

    June 7, 2013 – 3:00 am
  • All-solid sulfur-based battery outperforms lithium-ion technology - Scientists at the U.S. Dept. of Energy (DOE)'s Oak Ridge National Laboratory (ORNL) have designed and tested an all-solid lithium-sulfur battery with approximately four times the energy density of conventional lithium-ion technologies that power today's electronics. The ORNL battery design, which uses abundant low-cost elemental sulfur, also addresses flammability concerns experienced by other chemistries.
