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 ...

Freezing lithium batteries may make them safer and bendable

Yuan Yang, assistant professor of materials science and engineering at Columbia Engineering, has developed a new method that could lead to lithium batteries that are safer, have longer battery life, and are bendable, providing ...

The world's first heat-driven transistor

Dan Zhao and Simone Fabiano at the Laboratory of Organic Electronics, Linköping University, have created a thermoelectric organic transistor. A temperature rise of a single degree is sufficient to cause a detectable current ...

Solid electrolytes open doors to solid-state batteries

Japanese scientists have synthesized two crystal materials that show great promise as solid electrolytes. All-solid-state batteries built using the solid electrolytes exhibit excellent properties, including high power and ...
