The sodium-ion battery mainly includes five parts: positive electrode material, negative electrode material, electrolyte, current collector and separator.
The chemical formula of sodium iron sulfate is Na2Fe2 (SO4) 3, and its structure is composed of sodium ions Composed of iron ions and sulfate ions. In electrochemical reactions, sodium iron sulfate can release or absorb metal ions such as lithium ions and sodium ions through ion exchange reactions, achieving the charging and discharging process of 1
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.
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.
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
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%.
