Using a unique form of X-ray imaging, researchers have managed to identify transient crystal defects in the cathode of a sodium-ion battery.

Sodium-ion batteries have been touted as a sustainable alternative to lithium-ion batteries because they are powered by a more abundant natural resource. However, sodium-ion batteries have hit a s ...

Edwin Fohtung is leading a team of researchers that has combined expertise in mathematics and condensed matter physics with advanced scientific technology to uncover remarkable characteristics of magnetic ferroelectric materials.

Some imperfections pay big dividends. A Cornell-led collaboration used X-ray nanoimaging to gain an unprecedented view into solid-state electrolytes, revealing previously undetected crystal defects and dislocations that may now be leveraged to create superior energy storage materials. The group’s paper, “X-ray Nanoimaging of Crystal Defects in Single Grains of Solid-State Electrolyte Li7-3xAlxLa3Zr2O12,” published April 29 in Nano Letters, a publication of the American Chemical Society. The paper’s lead author is doctoral student Yifei Sun. American Chemical Society/Provided T...
