1.1.1 Superior Capacity Retention of Sodium-ion battery in Extreme Temperatures

Sodium-ion battery are champs when it comes to handling extreme temperatures, operating effectively between -40 degrees C and 80 degrees C. They discharge at over 100% of their rated capacity in high temperatures (55 degrees C and 80 degrees C) and still retain more than 70% of their rated capacity at -40 degrees C. They also support charging at -20 degrees C with nearly 100% efficiency.

In terms of low-temperature performance, Sodium-ion battery surpass both LFP and lead-acid batteries. At -20 degrees C, Sodium-ion battery keep about 90% of their capacity, whereas LFP batteries drop to 70% and lead-acid batteries to just 48%.

1.1.2 Exceptional Rate Performance of Sodium-ion battery

Sodium ions, thanks to their smaller Stokes diameter and lower solvation energy in polar solvents, boast higher electrolyte conductivity compared to lithium ions. The Stokes diameter is a measure of the size of a sphere in a fluid that settles at the same rate as the particle; a smaller diameter allows for quicker ion movement. Lower solvation energy means sodium ions can more easily shed solvent molecules at the electrode surface, enhancing ion diffusion and speeding up ion kinetics in the electrolyte.

1.1.3 Superior Safety Performance of Sodium-ion battery Under Extreme Conditions

Lithium-ion batteries can be prone to thermal runaway under various abusive conditions, such as mechanical abuse (e.g., crushing, puncturing), electrical abuse (e.g., short circuits, overcharging, over-discharging), and thermal abuse (e.g., overheating). If the internal temperature reaches a critical point, it can trigger dangerous side reactions and cause excessive heat, leading to thermal runaway.

Sodium-ion battery, on the other hand, have not shown the same thermal runaway issues in safety tests. They've passed evaluations for overcharge/discharge, external short circuits, high-temperature aging, and abuse tests such as crushing, puncturing, and fire exposure without the risks associated with lithium-ion batteries.
