Sodium Manganese Oxide Cathode for Cost-Effective Sodium-Ion Batteries
Tezta NMO – Sodium Manganese Oxide (NaₓMnO₂)
Tezta NMO, is a next-generation cathode material developed for sodium-ion battery systems. Based on sodium manganese oxide chemistry, it leverages non-hazardous, non-toxic, and widely available elements, making it a safe, sustainable, and cost-effective alternative to lithium-based cathodes.
Designed for commercial readiness, Tezta NMO combines high phase purity, stable electrochemical performance, and industrial-scale manufacturability, supporting the rapid deployment of sodium-ion batteries for mobility and stationary energy storage applications.
Strategic Rationale
As global demand for large-scale energy storage grows, reliance on lithium, cobalt, and nickel introduces cost volatility and supply-chain risk. Sodium-ion technology addresses these challenges by offering:
- Abundant and globally available raw materials
- No dependence on lithium, cobalt, or nickel
- Lower material and system-level costs
- Enhanced safety and simplified logistics
- Compatibility with existing battery manufacturing infrastructure
Tezta NMO represents a practical cathode solution enabling this energy transition.
