The sodium-ion battery mainly includes five parts: positive electrode material, negative electrode material, electrolyte, current collector and separator.
Sodium nickel iron manganese oxide is a chemical substance with the chemical formula Na2NiFeMn06. 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 sodium1
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%.
Sodium vanadium phosphate(NVP)cathode material for sodium-ion batteries, has the advantages of high specific capacity, excellent rate performance and long cycle life.
Soft carbon has adjustable layer spacing and good electronic conductivity, and can be used for sodium battery and lithium battery,it is a common sodium battery material.
