Hybrid membrane doubles the lifetime of rechargeable batteries

The energy density of traditional lithium-ion batteries is approaching a saturation point that cannot meet the demands of the future—for example in electric vehicles. Lithium metal batteries can provide double the energy ...

An atomic look at lithium-rich batteries

Batteries have come a long way since Volta first stacked copper and zinc discs together 200 years ago. While the technology has continued to evolve from lead-acid to lithium ion, many challenges still exist—like achieving ...

Invention reduces risk of battery explosions

A deceptively simple sensor system developed at the U.S. Department of Energy's Pacific Northwest National Laboratory can prevent dangerous conditions from developing in outdoor battery cabinets.

A long-lasting, stable solid-state lithium battery

Long-lasting, quick-charging batteries are essential to the expansion of the electric vehicle market, but today's lithium-ion batteries fall short of what's needed—they're too heavy, too expensive and take too long to charge.
