APPLICATIONS OF TECHNOLOGY:
- Electric Vehicles
- Energy Storage and Battery Manufacturing
BENEFITS:
- Superior energy density and structural stability
- Free of nickel and cobalt
BACKGROUND:
The disordered rocksalt (DRX) cathode materials are new candidates in the field of lithium-ion battery technology, designed to enhance energy storage capacity while reducing costs. By eliminating the need for expensive metals such as nickel and cobalt, and mitigating the ethical and environmental issues around sourcing these metals, and exhibiting high energy density, these DRX materials are promising alternatives to layered oxide technology.
TECHNOLOGY OVERVIEW:
Researchers at Berkeley Lab have developed Lithium-Manganese DRX materials with high energy density and structural stability. Through a novel process DRX cathode materials can be activated to show excellent performance at large particle scale, which allows good cycling and practical electrode manufacturing. The cathodes have demonstrated high discharge capacities around 200 mAh/g and energy densities up to about 650 Wh/kg, with high stability.
DEVELOPMENT STAGE:
Laboratory scale, similar system validation in relevant environment
