Cell Lab Ultra-Thin Lithium Foil [80 mm x 5 µm, 50 m/roll]

Cell Lab Ultra-Thin Lithium Foil [80 mm x 5 µm, 50 m/roll]

Porous battery-grade lithium foil for electrode pre-lithiation in advanced battery research

General Description

Cell Lab ultra-thin lithium foil (5 µm thickness, 80 mm width) is specifically designed for uniform pre-lithiation of battery electrodes. The porous structure allows improved electrolyte infiltration and faster lithiation, making it highly effective for silicon-based and other high-capacity electrodes.

Pre-lithiation is a well-established method to boost electrode capacity, enhance first-cycle efficiency, and extend cycling performance. Unlike lithium powder, continuous porous foil enables uniform lithiation and roll-to-roll processing, supporting safe, simple, and scalable application in both laboratory and industrial battery research.

⚠️ Handling Notice: Lithium is extremely reactive in air. Packages must never be opened outside of an inert Argon-filled glove box (moisture < 2% RH).

FAQ

Q1: What makes porous lithium foil better than lithium powder for pre-lithiation?
Porous foil ensures uniform contact and electrolyte penetration, while powders can be inconsistent and difficult to handle.

Q2: Can the dimensions be customised?
Yes. Width, thickness, and pore density can be adjusted based on research requirements.

Q3: Is this foil suitable for silicon nanowire anodes?
Yes. Research led by Prof. Yi Cui (Stanford) demonstrated that pre-lithiation with lithium foil greatly improves the capacity of Si nanowire electrodes.

Q4: How should it be handled during transfer?
Due to its ultra-thin thickness, detaching from the protective film can be challenging. A rolling mill is recommended for safe transfer.

Q5: Is shipping restricted?
Yes. Classified as hazardous material (HAZMAT), requiring compliant packaging and regulated shipping.
