Even when a device is turned off, its battery gradually loses its charge and eventually some of its capacity for storing energy. Scientists have now documented this aging process in next-gen ...

Utilizing lithium metal as the anode in batteries stands out as an intelligent choice due to its superior energy density compared to other materials. Each wedge consists of different constructions of ...

Current lithium batteries are based on intercalation—lithium ions squeeze into spaces within electrode materials such as graphite. As a result, most of the battery’s volume and bulk is dedicated to ...

Linköping University in Sweden scientists have created a novel soft gel electrode that might revolutionize brain stimulation. According to this Wired article, the scientists developed a gel that, when ...
