| Abstract Scope |
Performance and cycle-life limitations in lithium-ion batteries (LIBs) remain key barriers to the widespread adoption of cost-effective renewable energy storage. Atomic-scale engineering of thin-film coatings via Atomic Layer Deposition (ALD) offers a nanotechnology-driven pathway to address these limitations. This work couples techno-economic analysis with experimental testing of alumina (Al2O3) ALD nano-coatings on NMC811 cathodes to address the gap in understanding optimal processing parameters and large-scale economic viability. Electrochemical characterization (i.e., constant-current/rate-capability cycling, cyclic voltammetry) revealed that coated cathodes experienced a 19% decrease in specific capacity, and uncoated cathodes a 37% decrease in capacity after 110 cycles at 0.5 C, though high C-rate performance was sacrificed. By integrating performance metrics into the Levelized Cost of Storage framework, this work aims to quantify how ALD-extended battery longevity translates into reduced costs, providing a data-driven basis for evaluating ALD coatings as an economically viable pathway for increasing LIB adoption. |
