Abstract: A process of electroless plating a tin or tin-alloy active material onto a metal substrate for the negative electrode of a rechargeable lithium battery comprising steps of (1) immersing the metal substrate in an aqueous plating solution containing metal ions to be plated, (2) plating tin or tin-alloy active material onto the metal substrate by contacting the metal substrate with a reducing metal by swiping one on the other, and (3) removing the plated metal substrate from the plating bath and rinsing with deionized water. A rechargeable lithium battery using tin or tin-alloy as the anode active material.
