Tohoku University scientists have developed a new fluorine-free calcium (Ca) electrolyte based on a hydrogen (monocarborane) cluster that could potentially realize rechargeable Ca batteries. The researchers say the new material, achieved by designing the coordination structure of Ca cation with a weakly coordinating anion and mixed solvents, shows markedly improved electrochemical performances such as high […]

Now Holograms Make Improved Solar Panels
May 26, 2021 | Leave a Comment
Open Image…Save ImageOpen Image (using #TmpD/ia)… University of Arizona researchers recently developed an innovative technique to capture the unused solar energy that illuminates a solar panel. The team created special holograms that can be easily inserted into the solar panel package. Each hologram separates the colors of sunlight and directs them to the solar cells within the solar panel. This […]

A Battery That Has 10,000 Charge Discharge Cycles
May 20, 2021 | 3 Comments
Cornell University researchers have now shown that a new technique incorporating aluminum results in rechargeable batteries that offer up to 10,000 error-free cycles. The researchers have been exploring the use of low-cost materials to create rechargeable batteries that will make energy storage more affordable. The cost of harvesting solar energy has dropped so much in […]

Brookhaven National Laboratory scientists have identified the primary cause of failure in a state-of-the-art lithium-metal battery, of interest for long-range electric vehicles: electrolyte depletion. Using high-energy x-rays, they followed the cycling-induced changes at thousands of different points across the battery and mapped the variations in performance. At each point, they used the x-ray data to […]
