Lithium, Sodium & Potassium Metal Anodes

Lithium, sodium, and potassium metal anodes are used in lithium, sodium, and potassium battery research, including half-cell testing, symmetric cells, metal deposition and stripping studies, electrolyte evaluation, and solid-state battery development.

This category includes metal discs, foils, strips, sheets, ring foils, collector-supported formats, free-standing metal anodes, and custom-sized products. Select the appropriate metal anode according to the battery chemistry, cell structure, dimensions, thickness, current collector, and packaging requirements.

Before ordering, confirm the metal type, purity, thickness, dimensions, support structure, packaging quantity, and storage requirements. The selected product should also match the target cell housing, fixture, separator, and laboratory handling conditions.

Before You Order

  • Confirm the metal type: lithium, sodium, or potassium.
  • Check the metal purity and thickness.
  • Confirm the disc diameter or foil length and width.
  • Choose aluminum, copper, or no current collector.
  • Decide whether you need pre-cut discs, punched parts, strips, or roll material.
  • Check the package quantity and storage requirements.
  • Confirm compatibility with the cell housing, fixture, separator, and assembly process.

For standard coin cells, pre-cut metal discs are usually the most convenient option. For custom cutting, pouch cells, or large-area electrodes, choose metal foils, strips, or sheets. Ring foils and custom geometries are suitable for special cell structures.

Frequently Asked Questions

Which product should I choose for a coin cell?

Choose a pre-cut metal disc that matches the usable internal area of the cell. Confirm the disc diameter, thickness, and current collector dimensions before ordering.

How should I choose between foil and disc formats?

Choose discs for direct assembly and consistent dimensions. Choose foils or sheets when you need to cut different sizes, build pouch cells, or prepare large-area electrodes.

What is the advantage of a current collector-backed product?

An aluminum or copper current collector can improve mechanical support and reduce deformation during transfer and assembly. Free-standing products are better suited to experiments focused on the metal itself or the metal interface.

How should I select the metal thickness?

Select the thickness according to the available cell space, target metal loading, active area, and assembly method. Changing the thickness may require you to review the cell spacing and test conditions.

Can custom sizes be supplied?

Custom discs, foils, strips, sheets, and ring foils may be available. Provide the metal type, dimensions, thickness, current collector, quantity, and target cell structure when requesting a quotation.

How should I select products for repeat experiments?

Use products with the same metal type, thickness, dimensions, support structure, and batch whenever possible. This helps reduce variation when comparing electrolytes, cycling performance, or metal deposition behavior.
