 1. Abundance and Affordability: Sodium is widely available, making sodium-ion batteries cheaper to produce compared to lithium-ion options. As demand rises for batteries of car batteries, sodium's abundance reduces material costs, making this technology a cost-effective alternative.

2. Environmentally Friendly: Sodium-ion batteries offer a greener solution compared to traditional lithium-ion batteries. They do not rely on scarce and ethically problematic materials like cobalt. This makes sodium-ion technology an environmentally sustainable choice for various cars.

3. Safety and Durability: Sodium-ion batteries are generally safer, as they are less prone to overheating and thermal runaway, which are risks associated with lithium-ion technology. For vehicles that are exposed to extreme environments, this improved safety is a key advantage, ensuring reliable performance in harsh conditions.

4. Performance in Extreme Temperatures: Vehicles often operate in environments with fluctuating or extreme temperatures. Sodium-ion batteries perform better in cold or hot climates, making them suitable for vehicles that must endure diverse weather conditions.

How to choose a car battery?

Before choosing a car battery, consider these key factors:

Battery Size: Ensure the battery fits your car’s battery tray. Refer to the vehicle manual for the correct group size (e.g., Group 24, 35).

Cold Cranking Amps (CCA): CCA measures the battery’s ability to start the engine in cold conditions. Choose a battery with a CCA rating that meets or exceeds your car’s requirements, especially if you live in colder climates.

Reserve Capacity (RC): This is the battery's ability to power your vehicle’s electrical system if the alternator fails. A higher RC can provide more backup power.

Battery Type:

• Lead-Acid: Affordable and widely used, but requires maintenance and has a shorter lifespan.


• AGM (Absorbed Glass Mat): Maintenance-free, durable, and offers better performance, particularly for high-demand vehicles.


• LiFePO4 (Lithium Iron Phosphate): Lightweight, long-lasting, with faster charging and deeper discharge capabilities, but more expensive.


• Sodium-ion: Emerging technology, offering better environmental sustainability and safety, but less energy density compared to lithium batteries.

Lifespan and Warranty: Choose a battery with a good lifespan and warranty for long-term reliability. Look for warranties of at least 3 years.
Quality: Opt for reputable brands that offer reliable products, and check user reviews for performance feedback.
