Sol-gel capacitor dielectric offers record-high energy storage

Using a hybrid silica sol-gel material and self-assembled monolayers of a common fatty acid, researchers have developed a new capacitor dielectric material that provides an electrical energy storage capacity rivaling certain ...

Researchers unveil mystery inside lithium oxygen batteries

With a high energy density, Li-O2 batteries have become a state-of-the-art battery technology. Inside the Li-O2 battery, the generation and disintegration of the discharged product solid lithium peroxide (Li2O2) have a significant ...

New capacitors to improve electric vehicles

Scientists from the National Physical Laboratory (NPL) have developed a new lead-free, high temperature ceramic capacitor that could improve the efficiency and reliability of electric and hybrid vehicles.

Plastic, paper or cotton: which shopping bag is best?

On March 1, New York State instituted its plastic bag ban, joining seven other states in an attempt to lessen litter, garbage in landfills, ocean pollution, and harm to marine life. March 1 was also the day that New York ...

Shrimp shells to produce electrodes for large storage batteries

A project by Spanish researchers and other collaborators at the Massachusetts Institute of Technology (MIT) suggests the use of chitin from shrimp shells to produce electrodes for vanadium flow batteries. The results of the ...

3-D printed batteries handle the squeeze

While flexible and stretchable electronics technologies have progressed in leaps and bounds over the past 10 years, batteries to power them have some catching up to do. Researchers in Singapore and China have now demonstrated ...
