Sodium-ion Battery Materials
Sodium-ion batteries (SIBs) are gaining traction as a more sustainable and potentially lower-cost alternative to lithium-ion batteries. While they share some similarities with lithium-ion batteries, the materials used in their cathodes and anodes differ due to the use of sodium ions (Na+) instead of lithium ions (Li+).
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. However, because sodium ions are larger than lithium ions, finding suitable cathode materials for SIBs can be trickier. The material needs to have a structure that can accommodate these larger ions and allow for efficient movement during charge/discharge cycles. 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, similar to the cathode, the anode material needs to have a structure that can handle this size difference and allow for efficient sodium ion movement.
Sodium-ion battery research is a rapidly developing field, and the landscape is constantly evolving. NEI is 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.
NEI is currently producing various materials for Sodium-ion batteries, such as our innovative selection of cathode and anode powders, ready-to-use cathode and anode electrodes sheets, and even solid electrolytes.

Solid Electrolytes for Sodium-ion Batteries
Na-ion Solid Electrolytes
The focus for NASICON (Sodium Superionic Conductor) materials in SIBs seems to be shifting towards their potential as solid electrolytes. Unlike traditional liquid electrolytes, solid electrolytes offer the potential for improved safety and potentially higher energy density. With their exceptional Na-ion conductivity, NASICON materials are well-suited for this role.
Sodium Aluminum Titanium Phosphate (or “NATP”) is a NASICON material being explored as a potential solid electrolyte material for sodium-ion batteries (SIBs).
