Re-energizing the lithium-ion battery

High costs, slow recharging rates, and limited lifetimes restrict the utility of lithium-ion batteries for electric vehicles, storing electricity from wind or solar power, and other applications. Scientists are resolving these deficiencies; however, few have focused on a key interaction that influences battery behavior—how the lithium ions move from one electrode to the other. Researchers at the Lawrence Berkeley National Laboratory and the University of California-Berkeley have taken up the challenge. Using experiments and theoretical calculations, they showed that the lithium ion's journey involves more intimate contact with the electrolyte molecules than previously thought.
