Batteries with metallic lithium anodes offer enhanced efficiency compared to conventional lithium-ion batteries because of their higher capacity. However, safety concerns and a short lifespan stand in the way. To...
Briefs: Materials
Metal-air batteries are one of the lightest and most compact types of batteries but when not in use, they degrade quickly, as corrosion eats away at their metal electrodes. While...
Briefs: Energy
Conventional electrolytes used in lithium-ion batteries that power household electronics like computers and cellphones are not suitable for lithium-metal batteries....
Briefs: Materials
Lithium-ion batteries commonly used in consumer electronics are notorious for bursting into flame when damaged or improperly packaged. Inspired by the unusual behavior of some liquids...
Briefs: Sensors/Data Acquisition
Researchers devised a method in which running a light emitting diode (LED) with electrodes reversed was able to cool another device nanometers away. They harnessed the chemical potential of...
