Features of Sodium Ion Battery Pack 

High Energy Density

Although it is slightly lower than lithium batteries, it is several times more than lead-acid batteries, and its performance is also continuously improving.

Long Cycle Life

2000-6000 charging and discharging cycles, its lifespan is longer than that of lead-acid batteries and is still being continuously improved. It is also safer to use.

Wide Temperature

The working temperature is from -40°C to 60°C. It can discharge normally at -40°C, and the capacity retention rate is above 80% at -20°C, solving the pain point of batteries in cold regions.

Over Discharging

Overcharging and over-discharging will not affect the lifespan and safety performance of sodium-ion batteries. This can prevent many after-sales issues related to deep discharge for both users and merchants.

High Rate

The charging and discharging rate is high, allowing for a full charge in just 20 minutes, much faster than lead-acid batteries. It is very suitable for applications that require fast charging or high power output.

Frequently Asked Questions

Sodium-ion batteries can power vehicles, and sodium-ion vehicle starter batteries have already been produced. They have great potential to become a key technology for future electric vehicles and to be widely used. However, their energy density, cycle life, and charging speed still have significant room for improvement. With the continuous efforts and research development by engineers, there will be moments that impress us.

The development history of sodium-ion batteries is actually shorter than that of lithium-ion batteries, and some of their key parameters still have significant room for improvement. For example, their energy density and cycle life are still at a relatively low level, but they are expected to catch up with lithium-ion batteries in the next two years. Given the very stable market position of lithium-ion batteries, sodium-ion batteries will need more time to continue expanding their market applications.

Both have their advantages and disadvantages. Although sodium-ion batteries have slightly lower energy density and cycle life, their safety performance and low-temperature performance are very good, even surpassing those of lithium batteries. The development potential of sodium batteries is immense, as sodium resources are very abundant. This means they can not only be supplied stably in future production but also continuously reduce costs.
