The self-improvement of lithium-ion batteries

(Phys.org)—The search for clean and green energy in the 21st century requires a better and more efficient battery technology. The key to attaining that goal may lie in designing and building batteries not from the top down, but from the bottom up—beginning at the nanoscale. A team of researchers from Argonne National Laboratory and the University of Chicago has taken such an approach by developing titanium dioxide (TiO2) electrodes that can actually improve their own electrochemical performance as they are used.
