Researchers develop energy-efficient process to recycle Li-ion battery cathodes

Green Car Congress

Engineers at the University of California San Diego and the University of California Los Angeles have developed an energy-efficient approach to regenerate Li-ion battery cathode materials (using LiCoO 2 as a model material) by hydrothermal treatment of cycled electrode particles followed by short annealing.

DRX Consortium to accelerate commercialization of disordered rock salt (DRX) cathode materials

Green Car Congress

DRX cathodes could provide batteries with higher energy density than conventional lithium-ion battery cathodes made of nickel and cobalt, two metals that are in critically short supply. In a rock salt structure, cations (positively charged ions) and anions (negatively charged ions) are arranged in a specific pattern.

Study quantifies impact of fuel composition on PM emissions from gasoline direct injection engines

Green Car Congress

Researchers from Tsinghua University and Peking University have investigated the effects of fuel properties on particulate emissions gasoline direct injection engines (GDI). Higher aromatics in gasoline resulted in much higher PM (mass), PN (particle number) and PAHs emissions, with higher toxicity to human health.
