  • Thick Coating (Higher energy density)
    • Thicker coating to be easier due to its binding capability improvement.
  • Cycle Performance (Longer life)
    • The adhesion between a foil and electrode gets very high. 
  • C-Rate Performance (Lower resistance)
    • V shaped cracks retain electrolytes well, improve its permeability to the deep and expand the reaction area.
