The status of the sodium ion battery industry

---Sodium ion batteries are alternatives in some niche areas

At present, the main competitive products in the sodium ion battery industry are lithium manganese oxide battery, lithium iron phosphate battery, lead acid battery and so on. By calculating the difference in the energy density of the positive and negative electrode of sodium ion, it can be concluded that the energy density of sodium ion is about 0.7-0.8 times that of lithium manganese oxide battery and lithium iron phosphate battery under the same technical conditions. The sodium ion battery has unique advantages in safety, cost and other aspects, so that it is expected to become another secondary battery technology to achieve large-scale commercial application in addition to lithium ion battery.

However, it is expected that it will take time for the large-scale mass production and large-scale commercial application of sodium ion batteries, and the application competition pattern with lithium ion batteries will not change significantly in the short term. In the future, with the technological breakthrough and the improvement of the industrial chain layout, sodium ion battery can replace low-speed electric vehicles and two-speed electric vehicles, two-wheeled electric vehicles, home / industrial energy storage, 5G communication base station, electric ships and other subfields, and has a broad development prospect.

---The global sodium-ion battery market size has increased significantly

At present, a total of more than 20 sodium ion battery enterprises in the world have initially developed related battery products, and respectively in the power base station energy storage, electric bicycles, data center and low energy consumption industrial forklift and other fields have been small-scale demonstration application, sodium ion battery industry has begun to take shape market. In 2023, the world's leading enterprises such as Faradion in the United Kingdom, Natron Energy in the United States, China's Zhongke Haina and Ningde Times will be further accelerated. Once the technological breakthrough is made, the scale of the industry will increase significantly.

According to a report released by global research firm BIS Research, the global sodium ion battery market was about $528 million in 2021 and about $549 million in 2022, and the Asia-Pacific region has become the largest market for sodium ion battery-related product applications due to the rapid growth of the new energy market.

---Major countries in the global distribution of sodium ion batteries

The global sodium ion battery market covers the main regions are North America, Europe, Asia Pacific region. From the perspective of specific countries, the global layout of sodium ion batteries are mainly the United States, the United Kingdom, France, China, Japan, Sweden and Australia.

Sodium-ion batteries have been valued by various countries around the world. As a "substitute" product of lithium ion battery, sodium ion battery has been the attention of various countries, the department of energy will sodium ion batteries as sodium ion battery development system, the eu energy storage plan "battery 2030" project will sodium ion battery in the lithium ion battery system first, China ministry of industry in 2021 will gradually start sodium ion battery industry standards, will make policy arrangements for the development of sodium ion battery. With the gradual success of the demonstration and application of sodium ion battery products, the mass production pace of sodium ion battery has begun to accelerate, and the industry is gradually moving towards industrialization.

Technical route of sodium-ion batteries

Material technology: Among the key materials of sodium ion battery, the cathode material is one of the main factors that determine the performance and cost of the battery, and it accounts for the largest proportion of the raw material cost, more than 30%. From the perspective of technical route development, based on the differentiation of cathode materials, sodium electricity has been developed into three technical routes: layered oxide, polyanionic compounds and Prussian blue compounds. Due to the different advantages and disadvantages of the three technical routes, and the different market demand and response speed, the industrialization progress is also different.

Among them, the layered transition metal oxide of sodium ions performs well in the three technical routes: energy density, cycle life, ratio performance and material cost, and has the longest theoretical cycle life, etc, the industrialization progress is slow due to the problems of crystallization, thermal runaway, short cycle life.

Patent technology: From the perspective of the popularity of the application of sodium ion battery patent technology, layered transition metal oxides have a high popularity of patent application, the total number of patent applications reaches 3042, and the number of applicants reaches 1267, far exceeding other sodium ion battery technology paths; from the technical span, the layered transition metal oxides span 147 IPC subcategories; from the perspective of technology market coverage, the patent technology of layered transition metal oxides and polyanionic compounds covers more than 40 countries and regions, indicating that these technologies receive worldwide attention and research.

Investment boom in sodium-ion batteries

Sodium ion battery technology has broad application prospects in energy storage, low-speed electric vehicles and other fields, and has become one of the important fields for enterprises to focus on and invest in. The project investment is mainly used for the construction of sodium ion battery production base, the technical breakthrough and industrialization development of key materials of sodium ion battery.

From the analysis of the sodium ion battery industry chain, 59% of the invested projects focus on the upstream positive and negative electrode materials and electrolyte key materials of sodium ion batteries; 24% of the invested projects focus on the research and development and production of midstream sodium ion batteries, and 14% of the invested projects focus on sodium ion battery solutions.

Overall, layered transition metal oxide sodium electricity is the fastest developing sodium ion battery technology, with a clear industrialization path and more enterprises in the bureau. Compared with other sodium ion battery technology routes, layered oxide sodium electricity has more advantages in energy density, cycle life, safety and stability.

At present, the development of sodium ion battery technology is in the stage of rapid evolution and innovation. From the overall trend, the current sodium ion battery is developing toward low cost, high density and long life, and then drives the technology change in the segmentation field.
