Cryo-electron microscopy sheds new light on batteries

The interface of the solid anode and the liquid electrolyte plays a crucial role in the performance of a lithium-metal battery, but characterizing the processes that happen at that intersection has been a challenge.

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 ...

Flexible solar cells: Will they someday power your devices?

Will you ever be able to charge your mobile device, car and even clothing with flexible solar cells? Researchers at Aalto University in Finland and Université de Montréal are studying whether the now-experimental technology ...

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 ...

Nanowires could make lithium ion batteries safer

From cell phones and laptops to electric vehicles, lithium-ion batteries are the power source that fuels everyday life. But in recent years, they have also drawn attention for catching fire. In an effort to develop a safer ...
