“…It is known that a protection layer material with Young’s modulus higher than 6 GPa is considered to be adequate . Computationally and experimentally, much higher mechanical modulus values have been verified for the Co–Sn alloys. , Therefore, Co 3 Sn 2 should possess sufficiently robust mechanical properties for it to serve as a good protection layer.…”

To realize high specific capacity Li-metal batteries, a protection layer for the Li-metal anode is needed. We are carrying out combinatorial screening of Li-alloy thin films as the protection layer which can undergo significant lithiation with minimum change in volume and crystal structure. Here, we have fabricated lithium-free binary alloy thin film composition spreads of Co 1−x Sn x on Cu layers on Si substrates. The crystallinity of the thin films was tuned by varying the deposition temperature followed by electrochemical lithiation to form Li-alloy ternary thin films. Synchrotron diffraction is used as the main tool to investigate the crystallinity of the films before and after lithiation. Co 3 Sn 2 alloy thin films are found to exhibit significant lithium uptake capacity while maintaining its structural integrity, and are thus a good candidate of the Li-metal protection layer.
