3D self-assembling nanostructure for cathodes enables very rapid charge and discharge without sacrificing capacity; potential for EVs

Green Car Congress

Researchers at the University of Illinois at Urbana-Champaign have developed a self-assembling three-dimensional nanostructure for battery cathodes (Li-ion and NiMH) that allows for faster charging and discharging without sacrificing energy storage capacity. Most capacitors store very little energy. Click to enlarge. This does both.

CalCars and PHEVs Frequently Asked Questions

Tony Karrer Delicious EVdriven

Dont PHEVs just shift pollution from gasoline cars to power plants? Vehicle-to-Grid (V2G) is the concept of using stored energy in a plug-in hybrids (or electric cars) battery to send power to the electrical grid when necessary. Lithium-Ion batteries share many characteristics with NiMH. What about battery safety?
