 Increase the adhesion between the aluminium foil and the active
material.                    

 Decrease the using amount of binder for the electrode                        

 Enhance energy density of the battery ,and lower the cost of the
electrode production                        

 Protect the AI current collector from surface corrosion and
oxidation.                       

 Decrease polarization                        

 Raise the pass rate of the cell                      

 Improve the rate capability                  

• Lithium-ion super capacitor.
