We separated the ballmilling procedure for the composite preparation into two steps. First, we used a wet milling to reduce, control, and measure the RP particlesize distribution. The composites were prepared by dry milling these RP particles of known size distribution with graphite. We found that the material with a Dv90 of μm has a short cycle life (significant capacity fade after 20 ...
