Effect of surface pre-treatment on the hydrophilicity and adhesive properties of multilayered laminate used for lithium battery packaging

► The aluminium foil used for lithium battery package was treated by different methods. ► The effects of treatment on the adhesive properties of the laminated were explored. ► Both the adhesive strength and the heat sealing strength are affected by the surface treatments. ► The porous surface can greatly enhance the adhesive strength and the heat sealing strength.
