Sodium metal has been demonstrated as promising anode material with high energy density for sodium-ion battery.
The main features and applications are shown below:
-
Half-Cell Testing: Researchers use them as a counter-electrode to test the performance of new cathode materials (like Prussian Blue analogues or layered oxides) without the interference of a complex anode.
-
Sodium Metal Batteries (SMBs): Development of high-energy-density batteries that use a pure metal anode instead of an intercalation material (like carbon).
-
Anode-Free Prototypes: Testing concepts where the sodium is plated directly onto a current collector during charging.
For the sodium foil, which not only can be used for cutting into disc for coin-cell application, but also can be used as anode electrode for pouch cell assembling and testing. There are two kinds of sodium foils, (1) one is pure sodium foil where both side is covered by the transparent protection membrane; (2) the other type has aluminum support, in which aluminum side is covered by a blue protection membrane and sodium side is covered by a transparent protection membrane.
| Part Number |
CSIBAESF (C-SIB-AE-SF) |
| Purity |
99.9% for sodium content |
| Sample Size |
1 roll/pack. Each roll is L350 mm*W80mm*T0.45mm Type 1: Pure sodium foil (0.45 mm thickness) Type 2: Composite sodium foil with aluminum support (450 mm thickness for sodium and 30 um thickness for Al) |
| Sample Package |
Sodium foil with or without aluminum support are firstly sealed in plastic container and further vacuum sealed in a aluminum-laminated bag. Finally, it was placed in a black container for safety transport.  |
| Attention |
The sodium foil roll must be opened and operated inside a glove box with Argon Gas and moisture less than 1%RH (0.1 ppm is better). |
