High Performance Battery Materials
Cathodes, Anodes, and Electrolytes
Just as is the case with lithium-ion batteries, cathode materials are a key component of Sodium-ion batteries. The composition of the cathode material determines the cell voltage and capacity, and thereby the energy density. Sodium-ion cathode materials are typically based on intercalation / de-intercalation compounds, where sodium ions provided by the cathode are inserted into the host lattice (anode) during charge and extracted during discharge, with minimal structural change in the host material.
In contrast to lithium, sodium is one of the most abundant elements in the earth’s crust. Consequently, Na-ion batteries have attracted much attention over the past few years. The choice of cathode material with a particular chemistry depends on various factors, including cell voltage, capacity, energy and power capabilities, cycle life, and temperature of operation.
NEI is actively involved in producing various compositions of Sodium-ion materials, such as:
NEI produces a variety of sodium-ion battery materials, which include sodium-based cathode and anode materials, their corresponding carbon-coated counterparts (3-5 wt.% carbon), and sodium-based solid electrolytes. NEI can customize the primary and secondary particle size, composition, and surface characteristics (e.g., electronically conducting coating layer) of available materials, as well as custom synthesize Na-ion materials upon request.
