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 […]

DOE/Brookhaven National Laboratory scientists have developed a new way to decipher the atomic-level structure of materials based on data gleaned from ground-up powder samples. They describe their approach and demonstrate its ability to solve the structure of a material that shows promise for shuttling ions through sodium-ion batteries.   The scientists at the U.S. Department […]

Scientists’ research at Tokyo University of Science led by Prof Shinichi Komaba discusses the recent advances, promises, and limitations of potassium-ion batteries. Concerns about the scarcity of lithium and other materials necessary in the now-ubiquitous lithium-ion batteries have recently driven many researchers to look for alternatives, such as sodium and potassium. Our modern lifestyle would […]

University of Illinois at Urbana-Champaign researchers show a technology that charges batteries for electronic devices could provide fresh water from seawater. Electricity running through a salt water-filled battery draws the salt ions out of the water. Illinois mechanical science and engineering professor Kyle Smith and graduate student Rylan Dmello’s work has been published in the […]
