UCSD researchers improve method to recycle and renew used cathodes from Li-ion batteries via eutectic molten salts

Green Car Congress

Researchers at the University of California San Diego have improved their recycling process that regenerates degraded cathodes from spent lithium-ion batteries. Illustration of the process to restore lithium ions to degraded NMC cathodes using eutectic molten salts at ambient pressure. —Zheng Chen.

PNNL: single-crystal nickel-rich cathode holds promise for next-generation Li-ion batteries

Green Car Congress

High-energy nickel (Ni)–rich cathode will play a key role in advanced lithium (Li)–ion batteries, but it suffers from moisture sensitivity, side reactions, and gas generation. The gliding occurs as the battery charges and discharges—lithium ions depart and return to cathode, straining the crystal ever so slightly each time.

Gravity Batteries, Green Hydrogen, and a Thorium Reactor for China

Cars That Think

As power grids everywhere increasingly rely on intermittent renewable energy, batteries and other forms of energy storage that can even out the bumps in supply and demand are taking on a crucial role. Molten salt nuclear reactors fueled by thorium were first investigated at Oak Ridge National Laboratory in the 1950s.
