  • Are Lithium-Ion Batteries Safe?

    Lithium-ion batteries are used in all kinds of devices. While there are very few safety issues relative to the millions of batteries in use, in light of some recent lithium-ion safety issues, Kris Van Cleave at CBS Evening News took a look at their safety. Read More

  • The Lightest Organic Radical Cation for Charge Storage in Redox Flow Batteries

    By systematically shedding molecular fragments of 2,5-di-tert-butyl-1,4-bis(2-methoxyethoxy)benzene that are considered important for radical cation steric stabilization, we discovered a minimalistic structure that retains long-term stability in its oxidized form and exhibits the intrinsic capacity of 161 mAh/g.
