Sodium have great advantage for vehicle starter battery application:
1. Ultra-wide temperature range: Sodium-ion batteries can start vehicles in extremely cold weather at -40℃, and can also be used in high-temperature environments up to 80℃. The ultra-wide operating temperature range enables the battery to adapt to harsher environments.
2. High discharge rate: Sodium ion battery support 10C discharge rate even at -40℃ super cold temperature. This point make it wonderful to work as starter battery. Specially at winter cold temperature area.
3. High safety: Via testing, sodium-ion batteries are non-flammable under various extreme conditions, and their safety performance is superior to that of lithium batteries.
4. Long cycle life: Sodium-ion batteries have a long cycle life, and as starter batteries, they can last as long as the vehicle itself, eliminating the need for replacement like lead-acid batteries.
5. Can start vehicle at 0V, easy for maintenance: Sodium-ion batteries can still start a car even when at zero voltage, and after charging, they can continue to be used without affecting their lifespan, making them easier to maintain than lithium-ion batteries.
6. Low cost: Sodium is abundant and inexpensive, which is conducive to reducing battery costs after its widespread use in the market.
7. Environmentally friendly: Sodium-ion batteries do not contain harmful substances and are environmentally friendly.
Below is the comparison of sodium-ion battery, lead acid battery and lifepo4 battery.
| Sodium-ion batteries | Lead acid batteries | LiFePo4 batteries | |
| Model | 12V30Ah | 12V30Ah | 12V30Ah |
| Temperature rage | -40℃~80℃ | 0℃-65℃( capacity high attenuation at low temperature) | -20℃~65℃ |
| Charging performance | support 3C high-current fast charging, taking about 20 minutes to fully charge | only can be charged slowly with a small current. It takes 5.5 hours to charge at 10A | can charge up to 1C-2C, and takes about 40 minutes to fully charge |
| Discharging performance | Continuous discharge rate of 10C or higher | discharge rate 3-5C | discharge rate 3-5C |
| Peak discharge：400A@3S(-40℃) | only can be used when the required power >50%, and the performance degradation is significant, | The discharge performance decreases significantly at low temperatures, can not discharge with high current when temperature below -20℃ | |
