Na batteries: Application and Testing Method Analysis 2026
Na batteries (SIBs) are considered a powerful complement to lithium-ion batteries due to their abundant sodium resources and lower production costs, showing immense potential especially in energy storage technology. As a type of secondary (rechargeable) battery, sodium-ion batteries function primarily through the movement of sodium ions between the positive and negative electrodes, operating on a principle similar to that of lithium-ion batteries. The electrode materials for sodium-ion batteries consist mainly of sodium salts, which are more abundant and cost-effective compared to lithium salts. Working Principle of Na Batteries The working principle of sodium-ion batteries is similar to that of lithium-ion batteries, based on the insertion/extraction (intercalation/deintercalation) process of sodium
