Utilizing a new hydrothermal method, ORNL researchers have found that ethanol can replace cobalt as a cathode material and creates a more uniform, round, and tightly packed particle (right) that is common in today's cathodes (left).

Exploring new chemistries to reduce the necessity for critical metals needed for renewable energy, especially in the form of batteries, Oak Ridge National Laboratory has developed a method for producing lithium-ion batteries without the need for cobalt.

With the future expectantly being powered with batteries, all walks of studious life have been knuckling down to improve a nearly half-century-...
