Electric car makers are intensely interested in lithium-rich battery cathodes that could significantly increase driving range. A new study opens a path to making them live up to their promise

Researchers find the most effective way to understand the electrochemical reactions of lithium-ion batteries and to learn how the batteries can be modified to become safer, stronger, longer-lasting, and cheaper

Capacity fade is the reason why a cell phone battery that used to last a whole day will, after a couple of years, last perhaps only a few hours

Columbia Engineers use ice-templating to control electrolyte structure in lithium batteries; solid-state is non-flammable, non-toxic and flexible with longer battery life

Novel technique may lead to longer battery life in portable electronics and electrical vehicles

The work focuses on rechargeable Lithium-ion batteries, which are used in cell phones, electric cars, laptops, and many other electronics

Short of carrying an external battery all the time, is there any way to extend the life of your smartphone battery?

Method developed at Berkeley Lab’s Advanced Light Source could help researchers improve battery performance

Researchers' work proposes an approach that challenges conventional wisdom

Researchers make batteries reliable and longer-lasting using a thin-film coating technique called atomic layer deposition
