Application

Our high-purity sodium nitrate is an essential precursor in the synthesis of sodium-ion cathode materials. It is commonly used in the preparation of layered oxides, both P-type and O-type, such as sodium cobalt oxide or nickel iron manganese oxide (NFM),[,] In a typical sol-gel synthesis sodium nitrate is dissolved in water with transition metal nitrates and a chelating agent to form a gel. The gel is dried and then calcined to yield the desired sodium cathode material. Our high-purity sodium nitrate has many additional uses beyond battery research, for example as a synthetic reagent for sodium materials or as an electrolyte in electrochemistry.

General description

Our battery grade sodium nitrate is a high-purity, anhydrous compound used in material synthesis, for example in the synthesis of sodium-ion cathode materials. Our material is carefully synthesized to minimize impurities like trace metals, lithium, potassium, and anion impurities like chloride and sulfate that impact the performance of synthesized products.
Sodium nitrate is used as an additive in sodium-ion batteries to improve electrolyte stability and enhance battery performance. Its role supports greener technologies by enabling safer, more efficient, and longer-lasting energy storage solutions, contributing to sustainable and environmentally friendly battery development.
