In this review, the corrosion failure behavior of the cathode aluminum current collector in lithium-ion batteries with organic electrolytes is comprehensively analyzed, and the corresponding protective strategies are systematically summarized. 1. Introduction Energy is a pivotal driver for advancing social and economic progress.
npj Materials Degradation 8, Article number: 43 (2024) Cite this article State-of-the-art lithium-ion batteries inevitably suffer from electrode corrosion over long-term operation, such as corrosion of Al current collectors. However, the understanding of Al corrosion and its impacts on the battery performances have not been evaluated in detail.
Aging commences immediately after battery assembly, triggered by the hydrolysis kinetics of LiPF 6 and H 2 O, resulting in the generation of HF which weakly but spontaneously reacts with the natural oxide layer Al 2 O 3. This reaction transforms the passivation layer components.
During this washing and transfer process, the Li metal skin was anticipated to form an electrolyte-derived SEI layer that would determine the nucleation behavior along the metallic skin underneath.
Method : Double-anonymous Revisions: 1 Screened for originality? Yes Aluminum metal has long been known to function as an anode in lithium-ion batteries owing to its capacity, low potential, and effective suppression of dendrite growth.
And in the case of lithium-sulfur batteries, the volume expansion and contraction of sulfur electrode materials during charge and discharge have also triggered contact issues between current collectors and electrodes, leading to corrosion.
