New type of electrolyte could enhance supercapacitor performance

Supercapacitors, electrical devices that store and release energy, need a layer of electrolyte—an electrically conductive material that can be solid, liquid, or somewhere in between. Now, researchers at MIT and several ...

Disorder can stabilize batteries

Novel materials can considerably improve storage capacity and cycling stability of rechargeable batteries. Among these materials are high-entropy oxides (HEO), whose stability results from a disordered distribution of the ...

Compound could transform energy storage for large grids

In order to power entire communities with clean energy, such as solar and wind power, a reliable backup storage system is needed to provide energy when the sun isn't shining and the wind doesn't blow.

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 ...

Energy hybrid—battery meets super-capacitor

Researcher at TU Graz demonstrates in Nature Materials that it is possible to combine the high-energy density of batteries with the high-power output of super capacitors in a single system – thanks to liquid energy storage ...

New 3-D design for mobile microbatteries

In the race towards miniaturization, a French-US team—mostly involving researchers from the CNRS, Université de Lille, Université de Nantes and Argonne National Laboratory (US) as part of the Research Network on Electrochemical ...
