Investigating the effect of screen-printed structured graphite electrodes with low tortuosity for high-capacity and fast-charging lithium-ion batteries

The surface tension of the graphite ink was measured to be ~ 6.2 dynes/cm using the pendant drop method (Fig. S1b)³⁶. The surface energy of copper foil (substrate) was also measured with de-ionized (DI) water and hexadecane as 76 dynes/cm based…
