Oak Ridge National Laboratory (ORNL) researchers have developed a new family of cathodes with the potential to replace the costly cobalt-based cathodes typically found in today’s lithium-ion batteries that power electric vehicles and consumer electronics. The new family class named NFA, which stands for nickel-, iron- and aluminum-based cathode, is a derivative of lithium nickelate […]

Although touted as the best clean energy carrier, the explosive nature of dihydrogen gas (H2) warrants highly […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… Scientists from Tokyo University of Science, Japan, have found an energy-efficient method to fabricate a hard carbon electrode with enormously high sodium storage capacity. The discovery could pave the way for next-generation sodium-ion batteries made with inexpensive and abundant materials, and having a higher energy density than lithium-ion batteries. Today, most rechargeable batteries are […]

A Helmholtz-Zentrum Berlin team has now presented a method to visualize convection in the electrolyte and to reliably simulate it in advance with a multiphysics model. Hydrogen produced by using solar energy could contribute to a climate neutral energy system of the future. But there are hurdles on the way from laboratory scale to large-scale […]

University of Hamburg scientists have pointed out how to create a time crystal in an intriguing class of materials, the high-temperature superconductors. They propose to drive these superconducting materials into a time crystalline state by inducing Higgs excitations via light. When you cool down liquid water, it crystallizes into ice. Consider a bucket filled with […]
