This image, created by a scanning electron microscope, shows the dual-gradient cathode particles fabricated by the Argonne team. The U.S. Department of Energy’s (DOE) Argonne National Laboratory has ...

Skoltech researchers have developed a new method to improve the cathode, a key battery component. They proposed doping the cathode material with high-valent tantalum and discovered that adding 0.5 ...

Artistic rendering illustrating the key finding that lowering the heat-up rate during cathode preparation for sodium-ion batteries eliminated the strain and cracking problem in core-shell particles ...

Hunan University researchers have created a layered oxide cathode for rechargeable lithium-ion batteries that requires incredibly little cobalt to achieve high safety, long life, and fast charging.
