Benchmarking of Cathode Materials for Sodium-Ion batteries
Despite the recent decrease in lithium carbonate prices and the subsequent reduction in the spotlight on sodium-ion batteries, the technology continues to present significant advantages, particularly as lithium prices are expected to fluctuate in the future. Notably, sodium-ion batteries offer robust performance at low temperatures compared to LFP, which could make them especially appealing for automotive start-stop systems and energy storage system (ESS) markets.
A recent market analysis (Jan–Oct 2025) indicates that approximately 3 GWh of sodium-ion batteries have been produced collectively by leading manufacturers such as CATL, HiNa, Veken, Histar and others. The cathode material landscape is currently dominated by polyanion compounds, accounting for around 70% of market share, with layered oxides following. Prussian Blue, while promising, remains a niche material at this stage.
At Chem4Batteries, we are actively investigating various cathode materials for sodium-ion batteries to optimise performance, reliability, and cost-effectiveness. Our research addresses key challenges such as phase purity, efficient carbon coating processes, and the improvement of production methods to enhance material uniformity, manufacturing capacity, and overall system performance.
If your organisation is considering advancements in sodium battery technology—whether for benchmarking, electrode development, or cell prototyping—our team is ready to provide expert support and collaborative solutions.
