Making sodium-ion batteries that are worth their salt

(PhysOrg.com) -- Although lithium-ion technology dominates headlines in battery research and development, a new element is making its presence known as a potentially powerful alternative: sodium.

Graphene nanocomposite a bridge to better batteries

Researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have created a graphene and tin nanoscale composite material for high-capacity energy storage in renewable lithium ion ...

Simple lithium good for many surprises

(PhysOrg.com) -- At first glance, lithium should be a simple atomic system. It is the lightest solid element and with just three electrons, it should exhibit simple, crystalline structures. However, an international team ...

Energy storage using oxygen to boost battery performance

Researchers have presented a novel electrode material for advanced energy storage device that is directly charged with oxygen from the air. Professor Jeung Ku Kang's team synthesized and preserved the sub-nanometric particles ...

Peering into batteries: X-rays reveal lithium-ion's mysteries

Billions of smartphone owners are familiar with the dreaded "low battery" symbol on their devices. While consumers groan, scientists are working to understand why and when lithium-ion batteries in phones, plug-in electric ...

Lithium-ion batteries: Capacity might be increased by six times

The team was able to show through neutron measurements made at the Institut Laue-Langevin in Grenoble, France, that lithium ions do not penetrate deeply into the silicon. During the charge cycle, a 20-nm anode layer develops ...
