Na Ion Button Battery Negative Materials Na Metal Chips Sodium Chips For Sodium Ion Battery
The diameter of the sodium sheet is 15.6mm, the thickness is 0.4~0.5mm, and the purity is more than 99.7%. It is specially used for button batteries (2032, 2025, 2016). The sodium sheet has uniform size, smooth and bright surface, can be stored for a long time, and can be used as needed, which greatly improves the battery assembly efficiency, performance consistency and stability, and avoids the low battery assembly efficiency caused by the self-made sodium sheet. 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 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 bags, then put them in aluminum plastic bags, and then put them in iron tins for preservation, so as to ensure long-term preservation and safety.
