NIMS researchers report 500 Wh/kg+ Li-air battery

Green Car Congress

Lithium-air batteries have the potential to be lightweight and high capacity, with theoretical energy densities several times that of currently available lithium ion batteries. Because of these potential advantages, they may find use in a wide range of technologies, such as drones, electric vehicles and household electricity storage systems.

Caterpillar Marine Power Systems introduces Marine Hybrid System

Green Car Congress

With only the diesel engine providing power, the electric motor acts as a shaft-driven generator providing power to meet the vessels hotel loads. Auxiliary generators and optional electrical storage provide power for propulsion through the electric motor during electric or diesel-electric modes of operation.
