Details
This product is a sodium-ion cathode material of the polyanion type, specifically developed for advanced energy storage research. It features high first-cycle efficiency, excellent rate capability, and superior cycling stability, making it suitable for evaluating next-generation sodium-ion battery performance. Due to its hygroscopic nature, the material requires vacuum-sealed storage and strict humidity control throughout handling and electrode preparation. Recommended testing conditions include using sodium-ion electrolyte KLD-NC06 and baking electrodes at 105°C for four hours. Half-cell test data confirm its stable electrochemical behavior under various charge-discharge protocols. Available in quantities from 10 g to 1000 g, this material supports reproducible battery research from laboratory scale to expanded studies.
