(Phys.org) —Although sodium-ion (Na-ion) batteries don't perform as well as lithium-ion (Li-ion) batteries, they have the potential to be a cheaper alternative. In a new study, scientists have designed a new cathode for ...
(Phys.org)—The world of rechargeable batteries is full of trade-offs. While lithium-ion (Li-ion) batteries are currently the most commercially successful, their low energy density doesn't allow for a long driving range. ...
(PhysOrg.com) -- By wrapping tiny sulfur particles in graphene sheets, researchers from Stanford University have synthesized a promising cathode material for rechargeable lithium-sulfur batteries that could be used for powering ...
(PhysOrg.com) -- While car companies race to develop electric and hybrid electric vehicles, one of the biggest challenges they face is finding a suitable energy storage system. Lithium-ion batteries, which currently power ...
A promising technology under development by major battery makers has become even more attractive, thanks to researchers who have taken an unprecedented look at one key barrier to better, longer-lasting lithium-ion batteries.
