It is specially designed for button batteries (2032, 2025, 2016) to use composite sodium sheets, with a diameter of 15.6mm, a thickness of 0.4~0.5 mm, and a purity of more than 99.7%.
Foam nickel is a kind of porous metal with three-dimensional full through mesh structure, which is made of foam like metal nickel through high-tech deep processing.
Prussian white (PW), which is the fully reduced and sodiated form of prussianblue(PB), which is called Prussian white because it contains high sodium (Prussian blue contains only one sodium) and appears white. PW could significantly improve the manufacturability of commercial batteries as it circumventsthe requirement of a reactive sodium-load1
Sodium nickel iron manganese oxide is a chemical substance with the chemical formula NaNi1/3Fe1/3Mn1/3O2 . It is a composite oxide composed of four elements: sodium, nickel, iron, and manganese. Sodium nickel iron manganate has excellent electrochemical performance and is widely used in the field of batteries.
Compared with traditional copper foil, PET substrate has good safety performance, light weight, and good ductility, which can help improve the energy density of batteries.
Composite aluminum foil is a new-type of battery current collector, which has thinner aluminum film, overall lighter weight, and higher safty during penetration expeirment compared to the conventional rolling aluminum foil.
Sodium Nickel Iron Manganate Coated on Aluminum Foil,The contact between the particles and the current collector is better, and the internal resistance of the battery is smaller, which is conducive to the exertion of gram capacity and improves cycle and rate performance.
