Abstract: Lithium ion battery technology is the state-of-the-art rechargeable energy storage technology for electric vehicles, stationary energy storage and personal electronics. However, a wide variety of degradation effects still contribute to performance limitations. The metallic copper and aluminium current collectors in a lithium ion battery can be subject to dissolution or other reactions with the electrolytes. Corrosion of these metal foils is significantly detrimental to the overall performance of a lithium ion battery, however the mechanisms of this degradation are poorly understood. This review summarises the key effects contributing to metal current collector degradation in lithium ion batteries as well as introduces relevant corrosion and lithium ion battery principles. By developing the understanding of these complex chemistries, lithium ion battery degradation can be mitigated, enabling safer operation and longer lifetimes.
