Large flake can be usedChinese use -100 mesh to make spherical graphite for Li ion batteries because that is all they have and large flake is too valuable. Yield is only 30%. Large flake can and will be used as demand grows. The price gap between -100 and large flake has narrowed because of battery demand. Apparantely NGC has already done it and yield is much better than Chinese using Bissett Creek large flake so it is better for Li ion batteries.
