Cathode and Anode Powders for Sodium-ion Batteries

In contrast to lithium, sodium is one of the most abundant elements in the earth’s crust. As a result, Sodium-ion batteries (SIBs) are gaining traction as a more sustainable and potentially lower-cost alternative to lithium-ion batteries. Similar to lithium-ion batteries, the cathode in a SIB is the positive electrode responsible for storing sodium ions during charging and releasing them during discharge. The anode in a SIB acts as the negative electrode, accepting sodium ions during charging and releasing them back into the electrolyte during discharge. Since sodium ions are larger than lithium ions, both the cathode and anode material needs to have a structure that can handle this size difference and allow for efficient sodium ion movement.

Unlock Sustainable Battery Power with NANOMYTE®

NEI is at the forefront of the sodium-ion battery revolution, supplying researchers and developers with the essential building blocks: advanced cathode and anode materials specifically designed for sodium-ion batteries. We are actively exploring new and improved cathode and anode materials to address the challenges of sodium-ion size and optimize performance. The focus is on developing materials that offer high capacity, long cycle life, stability, and affordability to make SIBs a compelling alternative to lithium-ion batteries.

NANOMYTE® Cathode and Anode Powders

Cathode Materials for Na-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. Na-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.

NEI produces a wide variety of sodium-ion cathode materials. In addition to the standard specifications shown below, we can also customize the primary and secondary particle size, composition, and surface characteristics (e.g., electronically conducting coating layer) of available materials.

Our Na-ion cathode powders are available in quantities of 50 grams (minimum*), 100 grams, 250 grams, 500 grams, 1 kilogram or more.

*Except our Prussian materials. Prussian Blue is available in 25g and 50g quantities only; Prussian White is available in 25g, 50g, 100g, and 250g quantities only.
