1. Advantages of Sodium ion Battery in Low-Temperature Environments

Comparison of Low-Temperature Performance between Sodium ion and Lithium ion Battery

• Low-Temperature Discharge Performance: At -20℃, sodium ion Battery retain over 20% more capacity than lithium ion Battery.
• Low-Temperature Charge Performance: At -20℃, sodium ion Battery charge over twice as fast as lithium ion Battery.
• Low-Temperature Safety Data: Studies show that at -40℃, the probability of thermal runaway in sodium ion Battery is only 0.01%, compared to 0.1% in lithium ion Battery.
• Low-Temperature Cycle Life: Sodium ion Battery can achieve over 5000 cycles in low temperatures, while lithium ion Battery may only reach around 2000 cycles.

Sodium ion Battery outperform lithium ion Battery in low-temperature environments, making them an ideal choice for applications in cold regions.

• Wider Operating Temperature Range: Sodium ion Battery operate between -40℃ and 100℃, whereas lithium ion Battery generally operate between -20℃ and 60℃. This allows sodium ion Battery to function in more extreme conditions, such as:
  • Cold Regions: In extremely cold weather, sodium ion Battery maintain good discharge performance, providing reliable power for electric vehicles and drones. For example, some electric vehicles in Norway have started using sodium ion Battery, performing well even at -30℃.
  • Hot Regions: Sodium ion Battery work stably in hot environments, reducing the risk of thermal runaway. They are used in some solar energy storage projects, operating reliably in high-temperature, high-humidity conditions.
• Superior Low-Temperature Discharge Performance: Sodium ion’s faster migration rate compared to lithium ions results in better discharge performance in low temperatures. For example, at -20℃, sodium ion Battery retain over 90% capacity, while lithium ion Battery retain around 70%.
  • Longer EV Range in Winter: Electric vehicles powered by sodium ion Battery can maintain longer ranges in cold winters, alleviating range anxiety.
  • Higher Renewable Energy Utilization: In cold regions, renewable energy generation from wind and solar is often high, but lithium ion Battery’ efficiency drops. Sodium ion Battery better utilize these clean energy sources, increasing energy efficiency.
• Faster Low-Temperature Charging Speed: Sodium ion Battery charge quickly in low temperatures due to their faster ion intercalation/deintercalation rates. For instance, at -20℃, sodium ion Battery can charge 80% in 18 minutes, while lithium ion Battery may take over 30 minutes.

2. Advantages of Sodium ion Battery in High-Temperature Environments

Comparison of High-Temperature Performance between Sodium ion and Lithium ion Battery

• High-Temperature Discharge Performance: At 50℃, sodium ion Battery retain over 15% more capacity than lithium ion Battery.
• High-Temperature Charge Performance: At 50℃, sodium ion Battery charge over twice as fast as lithium ion Battery.
• High-Temperature Safety Data: Studies show that at 100℃, the probability of thermal runaway in sodium ion Battery is only 0.02%, compared to 0.15% in lithium ion Battery.
• High-Temperature Cycle Life: Sodium ion Battery can achieve over 3000 cycles in high temperatures, while lithium ion Battery may only reach around 1500 cycles.

In addition to their superior performance in low temperatures, sodium ion Battery also excel in high-temperature environments, expanding their application scope.

• Stronger Thermal Runaway Resistance: The more stable cathode materials of sodium ion Battery result in lower risks of thermal runaway at high temperatures, making them suitable for high-temperature applications such as deserts and solar power plants.
• Superior High-Temperature Discharge Performance: Sodium ion Battery maintain high capacity retention at high temperatures, such as over 95% at 50℃, compared to around 80% for lithium ion Battery.
• Faster High-Temperature Charging Speed: Sodium ion Battery can charge quickly in high temperatures, such as 80% in 15 minutes at 50℃, while lithium ion Battery may take over 25 minutes.

3. Mechanism Analysis: The Reason Behind Sodium ion Battery Low and High-Temperature Characteristics

The unique material and structural design of sodium ion Battery underpin their exceptional low and high-temperature characteristics.

• Sodium Ion Size: Sodium ions are larger than lithium ions, making them easier to shuttle in the electrolyte, maintaining high migration rates in both low and high temperatures.
• Electrolyte: Sodium ion Battery use electrolytes with lower freezing points and higher ionic conductivity, maintaining good conductivity in low temperatures and stable performance in high temperatures.
• Battery Structure: The specially designed cathode and anode materials in sodium ion Battery enhance their activity in both low and high temperatures.
