Ecological power storage battery made of vanillin

Researchers at TU Graz have found a way to convert the aromatic substance vanillin into a redox-active electrolyte material for liquid batteries. The technology is an important step toward ecologically sustainable energy ...

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 ...

Cheap, sustainable battery made from tree bark tannins

(Phys.org)—Tannins may be best known for their presence in red wine and tea, but in a new study researchers have demonstrated for the first time that tannins from tree bark can also serve as battery cathode materials. As ...

Improved redox flow batteries for electric cars

A new type of redox flow battery presents a huge advantage for electric cars. If the rechargeable batteries are low, the discharged electrolyte fluid can simply be exchanged at the gas station for recharged fluid -- as easy ...

Start-up aims at producing sodium-ion batteries

Two years after the first battery prototype using sodium ions in a standard industrial format was designed, the start-up Tiamat has been created to design, develop and produce this promising technology. This could counter ...
