Effect of slight structural difference in polyvinylidene fluoride binders on the electrochemical performance of single-crystal LiNi0.5Co0.2Mn0.3O2 cathode

When PVDF binders with different phase proportions were used for binding NCM523 SC active materials, it was found that PVDF with a higher β-phase content contributed to enhancing the ion conductivity and surface structural stability of the active materials.
