New study suggests stress among misaligned particles in typical lithium battery cathodes limits flow

"lithium can't go into the cathode uniformly... it slows down the intercalation mechanics... make lithium insertion or extraction more uniform on these aggregates or individual particles... Introducing some porosity in the particle agglomerates might sacrifice some energy density, but at the same time would allow lithium to go in more uniformly. That could allow you to get more energy at a given charge/discharge rate"
