Although the decline in lithium prices in the first half of the year has impacted the industrialization process, the development of the sodium battery industry chain and breakthroughs in application projects indicate its market potential. At the 8th International Power Battery Application Summit, industry insiders discussed the current cost of sodium batteries, which can be as low as 0.4 yuan/wh. However, there is still uncertainty and lack of confidence about the current cost of sodium batteries. The focus of industrialization progress has shifted from cost comparison to specific scenarios such as low temperature and rate performance requirements.

Experts at the summit believe that sodium batteries are expected to be mass-produced in small batches in the energy storage field next year. To further support the growth of the sodium battery industry, the China Chemical and Physical Power Supply Industry Association has released the "General Specification for Sodium Ion Batteries." This standard covers three application areas: electric vehicles, small power and light power, and energy storage. The specification was developed in collaboration with leading battery manufacturing companies, suppliers, and research units in the field of sodium-ion batteries.

While progress has been made in the sodium battery industry chain and application projects, the decline in lithium prices has affected the industrial development of sodium batteries. The high cost of sodium batteries compared to lithium batteries is the main obstacle to industrialization. Although the cost of sodium batteries has been reduced compared to the previous year, it still cannot compete with lithium batteries, particularly lithium iron phosphate batteries.

Despite the challenges, industry insiders have shifted their focus from cost comparison to the unique advantages of sodium batteries, such as their remarkable performance in low temperature and rate scenarios. The built production capacity of the sodium battery material side has been implemented, and large-scale orders have been received. However, some companies are struggling to meet the demand and deliver orders due to insufficient production capacity.

Sodium batteries have found applications in fields such as start-stop power supply and backup power supply, which prioritize magnification and low-temperature performance. However, in terms of energy storage applications, sodium batteries are still in the early stages as their cost and cycle performance cannot compete with lithium batteries. The energy density of sodium batteries is lower compared to lithium batteries, ranging from 100 to 160Wh/kg. Additionally, the cycle life of sodium batteries is shorter compared to lithium batteries, limiting their applications in both power and energy storage fields.

Despite these limitations, sodium batteries are recognized as "potential stocks" in the energy storage market. The use of polyanions as the main cathode material in sodium batteries for energy storage is expected to improve their performance and expand their applications. Continued research and development efforts are necessary to enhance the energy density and cycle performance of sodium batteries and enable their widespread adoption in various industries.

In conclusion, while the decline in lithium prices has impacted the industrialization of sodium batteries, the development of the sodium battery industry chain and application projects demonstrate its market potential. Efforts are ongoing to reduce the cost of sodium batteries, but they still cannot compete with lithium batteries in terms of price. However, industry insiders have shifted their focus to the differentiated advantages of sodium batteries in specific scenarios such as low temperature and rate performance. The sodium battery industry has made progress in terms of production capacity, but challenges remain in meeting the demand. Sodium batteries have found applications in start-stop power supply and backup power supply fields, but their energy storage capabilities still lag behind lithium batteries. Despite these limitations, sodium batteries are considered promising in the energy storage market, and further research and development efforts are needed to improve their performance and expand their applications.
