The proposed surface architecture and working mechanism of lithium supplement could effectively eliminate the remaining challenges of high-capacity Al anodes, promoting the possibility of using commercial aluminum foils as single-material anodes for high energy density lithium-ion batteries.
In summary, low-cost aluminum foils are employed as single-material anodes for Li-ion batteries that can match various commercial cathodes and potentially achieve higher energy densities. The roles of pre-lithiation, phase change, and morphology evolution on commercial Al foil anodes are comprehensively studied in Al||NCM full batteries.
Although it is very challenging to fabricate high-performance Al-based anodes for Li storage, commercial Al foils with different thickness were employed as single-material anodes in this study. An electrochemical prelithiation technology was used to replenish Li to the Al foils.
In this work, we develop a robust framework for understanding the implementation of alloying materials as foil anodes, surveying the full range of elemental metals to identify viable materials systems, and contextualizing their potential impact on performance.
As alloying-type anode materials, metallic aluminum owns an ultra-high specific capacity (993 mAh g A l - 1 to LiAl) for Li storage, which is low-cost and a promising candidate for next-generation rechargeable batteries with high energy densities.
The electrochemical performance of commercial Al foils with different thicknesses (200 μm, 100 μm, 50 μm, and 30 μm) as anodes were compared (Fig. S1, Supporting Information), and the 200 μm-thick Al foil which exhibited the best cycling performance was selected to investigate its morphology and composition after pre-lithiation.
