Processing battery-grade graphite involves two-stages: mechanically shaping natural graphite into small balls – "spheronising" it – then purifying it. While all but two to three per cent of minerals can be removed from graphite by standard physical methods, battery‑grade graphite needs to be at least 99.95 per cent pure to create long ...
