Built in sensors make lithium-ion batteries safer

Researchers in Penn State's Battery and Energy Storage Technology (BEST) Center are working to make the lithium-ion (Li-ion) batteries we use every day safer by inserting sensors to warn users of potential problems inside ...

Nanoparticles improve lithium battery electrodes

(Phys.org)—Materials scientists have developed a simple, robust way to fabricate carbon-free and polymer-free, lightweight colloidal films for lithium-ion battery electrodes, which could greatly improve battery performance.

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 ...

The secret of catalysts that increase fuel cell efficiency

Fuel cells, which are attracting attention as an eco-friendly energy source, obtain electricity and heat simultaneously through the reverse reaction of water electrolysis. Therefore, the catalyst that enhances the reaction ...

How fast you move can predict how healthy you'll be

Instead of focusing on drawing out the length of life, South Korea's IBS Center for Plant Aging Research and the research group led by Coleen Murphy, a professor at Princeton University have created a tool that can be used ...
