(Phys.org) -- When news broke in 2009 that a former IBM engineer had devised a kit that turns any car into a plug-in hybrid for between $3,000 and $5,000, those interested in going-green technologies took notice and hoped ...
Solid-state sodium-ion batteries are far safer than conventional lithium-ion batteries, which pose a risk of fire and explosions, but their performance has been too weak to offset the safety advantages. Researchers Friday ...
