What are sodium-ion batteries used for?

Sodium-ion batteries can be used for engine starting, industrial motive power, and stationary energy storage. Typical applications include automotive and marine starting, forklifts and material handling equipment, as well as rack-mounted, backup, solar, and commercial energy storage systems.

Can sodium-ion batteries replace lead-acid batteries?

Yes, in many applications. Sodium-ion batteries can be considered as an alternative to lead-acid batteries for starting, motive power, and energy storage. However, voltage, capacity, charging requirements, peak current, battery dimensions, terminals, and equipment compatibility should be checked before replacement.

Are sodium-ion batteries suitable for cold weather?

Yes. Sodium-ion batteries are known for strong low-temperature performance and can be suitable for cold-climate starting, industrial equipment, and energy storage applications. The actual charging and discharging temperature range depends on the battery model and system configuration, so operating specifications should be checked for each application.

What is the cycle life of a sodium-ion battery?

Polinovel sodium-ion batteries are designed for approximately 2,000–5,000 cycles , depending on battery configuration and operating conditions. This can help reduce replacement frequency compared with conventional lead-acid batteries.

Does Polinovel offer custom sodium-ion battery solutions?

Yes. Polinovel supports configuration options such as voltage, capacity, enclosure dimensions, terminals, BMS communication, and branding. Share your equipment or project requirements with our team to discuss the available options.

How do I choose the right sodium-ion battery?

Start with the application and required voltage. Then consider capacity, continuous and peak current, operating temperature, available installation space, and charger compatibility. Communication requirements should also be checked when connecting the battery to a vehicle or energy storage system.

How do sodium-ion batteries compare with lithium-ion batteries?

Both are rechargeable battery technologies, but they differ in energy density, temperature performance, and material composition. The better choice depends on the application, including available space, weight limits, power requirements, and daily usage.
