Using a pre-fabricated Lithium-Indium (Li-In) alloy coated copper foil is an excellent choice for roll-to-roll scaling and uniform pouch cell assembly. It completely bypasses the tedious, inconsistent process of manually laminating pure lithium and indium foils inside a glove box.
The structural layers of a pre-coated foil are stacked to optimize electronic contact and electrochemical boundaries: (1) Protective 0.62 V Barrier: When a pure lithium metal anode meets a sulfide solid electrolyte (Li6PS5Cl, LGPS), the extremely low chemical potential (~ 0 V) reduces the electrolyte, generating resistive decomposition products (Li2S, Li3P). The Li-In coating shifts the operational threshold up to ~ 0.62 V vs. Li/Li+. This thermodynamically protects the solid electrolyte separator from reduction. (2) Intimate Electronic Contact: Depositing the alloy layer directly onto a treated copper foil ensures a near-zero interfacial resistance on the backside of the anode, preventing local current hotspots.
