With the battery industry’s continued growth and demand, 2024 is shaping up to be a significant year for sodium batteries. This emerging technology is proving to be a viable alternative to traditional lithium-ion batteries and even revolutionary solid-state batteries. Compared to alternative battery technologies, sodium batteries have numerous advantages, including high-energy density, cyclability, safety, a plentiful supply of raw materials, cost-effectiveness, and sustainability.
A battery technology with exceptional commercial potential
According to market trends and data, sodium-ion battery production capacity is expected to grow significantly. The International Energy Agency predicts a 350% increase in production capacity, from 42 GWh to 186 GWh/year. Chinese manufacturers are primarily driving this growth, with nearly 95% of sodium-ion battery production expected by 2030.
The market value of sodium-ion batteries is expected to exceed 1 billion EUR by 2030, with compound annual growth rates (CAGRs) of more than 10%. Given the current state of technology, long-term projections are difficult to make, but in the next ten years, it is reasonable to anticipate exponential growth in the use, demand, and value of sodium batteries.
A broad range of applications in energy storage
For many applications, sodium-ion batteries are an excellent choice. Their affordability, stability, safety, and efficiency have made them promising for use in consumer electronics and stationary energy storage. Furthermore, recent advances in energy density have made sodium-ion batteries a viable option for electric mobility applications. There are already potential solutions that will provide a density of 200 Wh/kg, which enables an average electric vehicle to have a range of 500 kilometers.
Key players in the development of sodium-ion batteries
With the growing interest in sodium batteries, several industry leaders have emerged. CATL, the world’s largest battery manufacturer, has made significant technological advances and is at the cutting edge of sodium battery development. HiNa Battery, backed by the Chinese government, has been a major player with its 1 GWh production line. Northvolt, one of Europe’s leading battery manufacturers, has teamed up with Altris to introduce its first generation of sodium-ion battery cells with an energy density of 160 Wh/kg (read more).
However, not only are large manufacturers entering the sodium battery market, but startups have also played a significant role in the advancement of the technology. Companies such as Faradion, Tiamat Energy, and Natron Energy have been pioneers in developing sodium-ion batteries.
The Value of Battery Research and Development
The scientific community’s efforts have had a significant impact on the development of sodium-ion battery technology. Several prestigious academic organizations are in the process of creating sophisticated methods to enhance recognition of this promising alternative. Notable institutions involved in these advancements include MIT, the Helmholtz Institute, CNRS, and CIC energiGUNE.
The year 2024 is shaping up to be a year of great prominence for sodium batteries, not only because of the proliferation of key players but also because of the market prospects. This technological advancement has the potential to disrupt and speed up the process of electrification and energy transition in a variety of different industries and varieties of applications in energy storage and electric mobility.
