Batteries: Modeling tomorrow's materials today      (via sciencedaily.com)     Original source 

Which factors determine how quickly a battery can be charged? Microstructural models have helped researchers discover and investigate new electrode materials. When sodium-nickel-manganese oxide is used as cathode material in sodium-ion batteries, simulations reveal modifications of the crystal structure during charging. These modifications lead to an elastic deformation, as a result of which capacity decreases.
