Study: consumer products overtake transportation as largest source of VOCs air pollution in cities

Green Car Congress

Transportation emissions of NO x and VOCs have long been considered major contributors to formation of O 3 and SOA in urban areas, although recent studies have suggested the importance of nonvehicular sources as major contributors. As transportation gets cleaner, those other sources become more and more important. McDonald, Joost A.

International team develops technique to measure ion transport in LIBs precisely

Green Car Congress

Predictive knowledge of ion transport in electrolytes which bridges microscopic and macroscopic length scales is imperative to design new ion conductors and to simulate device performance. —Hans-Georg Steinrück, professor at Paderborn University and the first author. The principle is easy, but we had to measure accurately.

Colorado State University Spinoff to Commercialize 3D Li-ion Battery Technology for Higher-Capacity, Longer-Life Cells

Green Car Congress

The resulting transport of Li ions between the electrodes, usually arranged in a parallel-plate configuration, is 1-D in nature. To minimize power losses resulting from slow transport of ions, the thickness of the insertion electrodes, as well as the separation distance between them, is kept as small as possible. Credit: ACS.
