Comparison of Sodium and Lithium

Energy Density: Lithium cells, particularly the NMC and LFP types, offer higher energy densities compared to sodium cells. This makes lithium cells more suitable for applications where space and weight are critical factors.
Cost and Abundance: Sodium cells are generally more cost-effective due to the abundance of sodium, which is cheaper and more readily available than lithium. This makes sodium cells a more economical choice for large-scale applications.
Performance in Extreme Conditions: Lithium cells tend to perform better in extreme temperatures, offering consistent performance and longer cycle life. Sodium cells, while improving, still lag behind lithium cells in terms of operational range and efficiency in harsh environments.

How to Assemble Sodium-Ion Batteries

Preparation of Materials

Gather all necessary components, including sodium-ion cells, electrode materials, electrolytes, separators, and casings. Ensure all materials meet quality standards and specifications.

Electrode Assembly

Assemble the anode and cathode by coating the respective materials onto current collectors. Use precision machinery to ensure uniform coating thickness and adherence. Stack or wind the electrodes with a separator between them to prevent short-circuiting.

Cell Assembly and Sealing

Insert the electrode assembly into the battery casing and fill it with the electrolyte. Seal the battery casing hermetically to prevent leakage and contamination. Finally, perform initial charging and testing to ensure the battery operates correctly and meets performance standards.
