CATL, the Chinese battery giant, is expanding its sodium-ion battery (SIB) offerings, highlighting a significant upgrade and diversification of its product line for 2026. The company is positioning sodium and lithium batteries to work together seamlessly across various applications, including energy storage and transportation.
What are the Advantages of Sodium-Ion Batteries Over Lithium-Ion Batteries?
Sodium-ion batteries (SIBs) offer distinct advantages over traditional lithium-ion batteries (LIBs). One of the primary benefits is their ability to perform in extreme temperatures, ranging from -40°C to 70°C. This makes them suitable for use in regions where lithium-ion batteries struggle with cooling or heating requirements. Furthermore, sodium-ion batteries are noted for their lower carbon footprint, superior safety features, and potentially lower costs due to abundant raw materials.
SIBs also support a range of applications that were previously out of reach for LIBs, including passenger vehicles, commercial vehicles, and energy storage systems. As CATL continues to improve their performance, SIBs are likely to become a staple in multiple industries.

What is the Expected Energy Density and Range of CATL’s Sodium-Ion Batteries?
CATL’s 2026 sodium-ion batteries promise an impressive energy density of up to 175 Wh/kg. This enables passenger vehicles to achieve a range of up to 500 kilometers on a single charge. The improved energy density allows for longer-lasting, more efficient batteries that are compatible with a variety of electric vehicles, from cars to heavy-duty trucks.
With these enhancements, sodium-ion batteries are expected to become an essential part of the global energy transition, complementing lithium-ion solutions in areas where their limitations once posed challenges.
How Could Sodium-Ion Batteries Impact the Cost of Energy Storage Solutions?
The lower production cost of sodium-ion batteries could significantly disrupt the current energy storage market. According to a report by the International Renewable Energy Agency (IRENA), the cost of sodium-ion battery cells is expected to drop to as low as $40/kWh in the near future. This presents a more affordable alternative to lithium-ion batteries, especially for large-scale storage applications.
Sodium-ion batteries are expected to be a strong competitor in the stationary storage sector, where cost-efficiency and scalability are crucial for widespread adoption. As demand for energy storage solutions increases, SIBs will play a key role in reducing overall system costs.
