Polymer professor develops safer component for lithium batteries

The power source for implanted medical devices, electric cars, unmanned aerial vehicles and other such objects is vital to their performance. So, what would happen if that powerhouse of energy—a lithium battery—failed? ...

The science behind pickled battery electrolytes

Battery researchers at the U.S. Department of Energy's (DOE) Argonne National Laboratory have discovered an important chemical reaction that resembles the method used to make pickles. The reaction provides key insights into ...

Turbocharge for lithium batteries

A team of material researchers from Juelich, Munich, and Prague has succeeded in producing a composite material that is particularly suited for electrodes in lithium batteries. The nanocomposite material might help to significantly ...

Optimizing lithium-sulfur battery electrolytes for long life

In the future, lithium-sulfur (Li-S) rechargeable batteries could hold more energy and cost less than lithium-ion batteries if they can be made to last longer. A key challenge is preventing the polysulfide ions that must ...
