Abstract

Present invention is related to a composite modified layer attached on a current collector comprising a lithiophilic particle being covered or coated by a polymer layer. The composite modified layer further could be coated with an additional carbon layer or artificial protective film as several suitable embodiments presented in this invention. The lithiophilic particle, such as sliver nano-particle, will firstly form a lithium-silver alloys to reduce a thermodynamic instability during the growth of lithium nuclei. The sliver nano-particle is able to be attached securely on the current collector by the polymer with high adhesion ability. The fuel cell including the composite modified layer in the present invention has higher average Coulombic efficiency and higher capacity retention.
