Battery Particle Simulation_Advances on explaining why batteries fail and hence how they may be improved

Published on 15 Sep 2014 Two simulations show the differences between a battery being drained at a slower rate, over a full hour, versus a faster rate, only six minutes (a tenth of an hour). In both cases battery particles go from being fully charged (green) to fully drained (red), but there are significant differences in the patterns of discharge based on the rate.
