The high charge current produces a surface color, which corresponds to a state of charge of 70â80%, although the average SOC is just 45%. The high discharge current also forms a large gradient of the state of charge in the graphite anode, which is reflected in a black color. Due to this color we presume that the anode surface has a very low SOC.
