Sodium-ion Battery Solutions for Energy Storage, Forklift & Starting

Sodium-ion battery technology offers strong potential for low-temperature operation, high-rate power, and stable performance across demanding conditions. Combined with carefully selected battery materials, system protection, and BMS management, Polinovel sodium-ion batteries are engineered for reliable operation across energy storage, forklift, and engine-starting applications.
Wide-Temperature Performance
Wide-Temperature Performance
Polinovel sodium-ion batteries are designed to maintain stable performance across a wide temperature range, with selected models supporting operation from -30°C to 65°C. 
 
This makes sodium-ion technology especially suitable for environments where conventional battery performance may be affected by cold or changing temperatures.
High-Rate Power Output
Designed for high-rate charging and discharging, Polinovel sodium-ion batteries deliver fast power response and stable output when demand increases. 
 
This makes them well suited to applications that require strong instantaneous power and consistent performance under changing loads.
High-Rate Power Output

Sodium-Ion vs Lithium-Ion vs Lead-Acid Battery

Battery chemistry affects low-temperature performance, power capability, cycle life, charging requirements, and application suitability. Here is how lead-acid, lithium-ion, and sodium-ion batteries compare across starting, motive power, and energy storage applications.

  • Lead-Acid
    A mature battery technology widely used in engine starting, motive power, and backup applications.

    ✓ Low-Temperature Performance:
    Available output and capacity decline as temperature falls

    ✓ Power Capability:
    Proven for engine starting and conventional traction applications

    ✓ Cycle Life:
    Typically 300–500 cycles

    ✓ Charging:
    Mature charging infrastructure and broad system compatibility

    ✓ Typical Applications:
    Engine starting, conventional forklifts, backup power

  • Lithium-Ion
    Widely adopted where lower weight, fast charging, and extended cycling are important.

    ✓ Low-Temperature Performance:
    Charging at low temperatures may require thermal management

    ✓ Power Capability:
    High continuous and peak power with properly designed cells and BMS

    ✓ Cycle Life:
    Typically 3,000–5,000 cycles

    ✓ Charging:
    Supports efficient and relatively fast charging with a compatible charger and BMS

    ✓ Typical Applications:
    Electric forklifts, energy storage, EVs, and specially designed starting batteries

  • Sodium-Ion
    Designed for applications requiring reliable performance across starting, motive power, and stationary energy storage.

    ✓ Low-Temperature Performance:
    Strong low-temperature capability with model-specific operating ranges

    ✓ Power Capability:
    High-rate charge and discharge capability for starting and motive power applications

    ✓ Cycle Life:
    Up to 4,000+ cycles

    ✓ Charging:
    Battery voltage, current, BMS, and charging parameters are configured for the target application

    ✓ Typical Applications:
    Engine starting, forklifts & material handling, rack-mounted energy storage

Sodium-Ion Battery FAQs

  • Q What are sodium-ion batteries used for?

    A 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.

  • Q Can sodium-ion batteries replace lead-acid batteries?

    A 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.

  • Q Are sodium-ion batteries suitable for cold weather?

    A 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.

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

    A 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.

  • Q Does Polinovel offer custom sodium-ion battery solutions?

    A

    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.

  • Q How do I choose the right sodium-ion battery?

    A

    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.

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

    A

    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.
