Dry manufacturing process offers path to cleaner, more affordable high-energy EV batteries

The lithium-ion batteries used to power electric vehicles are key to a clean energy economy. But their electrodes are usually made using a wet slurry with toxic solvents, an expensive manufacturing approach that poses health and environmental risks.Early experiments at the Department of Energy’s Oak Ridge National Laboratory have revealed significant benefits to a dry battery manufacturing process.

Tracking Pileups on Battery Charging Route to Drive Performance

An understanding of this mechanism could help scientists increase the total amount of energy stored by next-generation lithium-ion batteries.

Battery Breakthrough Gives Boost to Electric Flight and Long-Range Electric Cars

Researchers at Berkeley Lab, in collaboration with Carnegie Mellon University, have developed a new battery material that could enable long-range electric vehicles that can drive for hundreds of miles on a single charge, and electric planes called eVTOLs for fast, environmentally friendly commutes.
