Abstract

Current collectors in lithium ion batteries are considered to give the electronic conduction to the electrode materials without electrochemical reactions. However, once the current collectors are thermally treated with active electrode materials, thermally treated current collectors might induce electrochemical reaction that affects the whole cell performance due to the interfacial layer formed by the thermal treatment. In this work, Ni foam and Cu foil current collectors were investigated to understand their capacity contribution and electrochemical properties after thermal treatment.
