Composite Sodium Metal Chips for Sodium-Ion Battery Research

Quick Answer

Composite sodium metal chips are pre-formed sodium electrode discs supported by aluminum foil and protected by removable films. They are designed for sodium-ion battery research to improve electrode handling, dimensional consistency, and coin-cell assembly efficiency.

Description

Composite sodium metal chips are designed for laboratory sodium-ion battery research and coin-cell assembly. Each electrode consists of a sodium metal layer supported by aluminum foil, with removable protective films on both sides for handling and storage.

Compared with manually prepared sodium discs, the pre-formed structure provides more consistent dimensions and a smooth electrode surface, helping reduce scratches, burrs, and dimensional variation during cell assembly.

The sodium layer has a nominal thickness of 0.45 mm and a purity of ≥99.7%. Standard diameters include 14 mm, 15.6 mm, and 18 mm, supporting different laboratory cell configurations. The original product specification describes the available diameters as 14 mm, 15.6 mm, and 18 mm and sodium purity as at least 99.7%.

Important Handling Notes

Sodium metal is highly reactive with air and moisture. Handle and open the product only under an appropriate inert-atmosphere glove box environment.
