The demand for high-performance batteries continues to grow, and with it, the need for materials that deliver reliability, purity, and performance at every stage of development.

At Avocet Precision Metals, we supply lithium metal foil specifically engineered for advanced energy storage applications. Our foil is available in single-sided and double-sided formats, with tight control over thickness and surface quality to meet the evolving requirements of next-generation battery technologies.

What Is Lithium Foil Used For?

Lithium foil is a key enabler in several emerging and high-performance battery chemistries thanks to its high energy density, low electrochemical potential, and reactivity with cathode materials. It is used in:

Anodes for lithium-metal and solid-state batteries

Pre-lithiation of silicon-carbon anodes in Li-ion cells to improve first-cycle efficiency

Lithium–sulphur and l

Pouch and cylindrical cell pilot lines

High-performance and defence-grade battery systems for aerospace and energy storage

Whether you’re building early prototypes or scaling low-volume production, we ensure consistent foil quality, traceability, and dependable delivery.

Why Choose Avocet?

Our customers choose us not only for supply, but for partnership and technical support throughout their development process.

Ultra-thin and wide lithium foils, precision-rolled for consistent thickness and uniform surface finish

Single-sided or double-sided foils available as free-standing lithium or laminated to substrates such as copper, stainless steel, or nickel

High-purity lithium (>99.9%) and lithium alloys (Li-Al, Li-Mg, Li-In, etc.)

Flexible supply formats for R&D, pilot lines, and specialised production environments

Secure, compliant packaging and international logistics, including documentation for hazardous materials

Application-driven support from initial design input through to integration and testing

We help battery innovators move faster, avoid delays, and maintain performance consistency from lab to pilot scale.

Product Overview

Our lithium foils are available in sheet or roll form, manufactured to precise tolerances:

Width: 10 mm – 400 mm

Thickness: 0.003 mm – 2 mm
