ANIMATION Like biological fat reserves store energy in animals, a new rechargeable zinc battery integrates into the structure of a robot to provide much more energy, a team led by the University of Michigan has shown. This approach to increasing capacity will be particularly important as robots shrink to the […]

Researchers report that while magnesium and other multivalent metals show promise for high-density energy storage, but a number of obstacles remain. They suggest next steps in search for large-scale energy storage solution. Lithium-ion batteries are recognized for their high energy density in everything from mobile phones to laptop computers and […]

Animation Researchers in the Cockrell School of Engineering at The University of Texas at Austin have built a new type of battery that combines the many benefits of existing options while eliminating their key shortcomings and saving energy. Most batteries are composed of either solid-state electrodes, such as lithium-ion batteries […]

Lithium being extracted from brine in Bolivia NOAH FRIEDMAN-RUDOVSKY/BLOOMBERG VIA GETTY IMAGES Booming electric vehicle sales have spurred a growing demand for lithium. But the light metal, which is essential for making power-packed rechargeable batteries, isn’t abundant. Now, researchers report a major step toward tapping a virtually limitless lithium supply: […]

The integrated solar flow battery device contains both a solar cell to convert sunlight into electricity and chemicals that can store the electricity for later use. Credit: Wenjie Li Chemists at the University of Wisconsin-Madison and their collaborators have created a highly efficient and long-lasting solar flow battery, a way […]
