Corrosion resistance of nickel foam modified with electroless Ni-P alloy as positive current collector in a lithium ion battery

We provide a novel and facile idea to enhance the corrosion resistance of nickel foam and improve the life of a positive current collector in an electrolyte containing LiPF₆ salt. The crystal Ni-P alloy was prepared via an electroless Ni-P technique, combined with subsequent thermal treatment. The as-prepared crystal alloy coatings exhibit excellent stability at high operating voltages as positive current collectors in lithium ion batteries.
