The diameter of the sodium metal chips is 15.6 mm, the thickness is 0.4~0.5 mm, and the purity is more than 99.7%. It is specially used for coin cell batteries (CR2032, 2025, 2016). The size of the sodium chips is uniform, the surface is smooth and bright, and it can be stored for a long time. are inconsistent, there will be burrs and scratches on the surface, which will affect the consistency of battery performance. Using quadruple protection packaging technology, the sodium sheet is covered with aluminum foil on one side, which acts as a support and current collector, and also plays the role of protecting the sodium. In addition, both sides are covered with a protective film, which can protect the sodium sheet and avoid oxidation. Put the sodium flakes in plastic bottles, then put them in aluminum plastic bags, and then put them in iron jars for preservation, so as to ensure long-term preservation and safety.

How to use sodium chips:

The protective film on the surface (both sides) of the sodium sheet can be used. One side of the aluminum foil is a blue protective film, and the other side of the sodium sheet is a transparent protective film, which can facilitate the observation of the surface of the sodium sheet. First peel off the blue protective film on one side of the aluminum foil, then peel off the transparent protective film on the side of the sodium sheet, and first clamp the entire sodium sheet with widened flat tweezers, so that the sodium sheet will not be severely deformed when the film is peeled off.

Then use stainless steel pointed tweezers or round-tipped tweezers to clamp a point on the edge of the sodium sheet and pull it outwards, start up, and then extend it along the edge, and then remove the protective film, and the entire film can be removed. When installing the battery, the aluminum foil is facing the battery case and the sodium sheet is facing the separator to assemble the button battery.
