Sodium-ion batteries are emerging as a superior alternative to traditional lead-acid batteries for automotive start-stop systems. Designed to handle the frequent engine restarts that strain conventional batteries, they offer a range of compelling advantages
Key benefits include a lifespan up to three times longer (up to 3,000 cycles vs. 500-1,200 for lead-acid) and ultra-fast charging, reaching full capacity in as little as 40 minutes.They also deliver 2-3 times greater starting power thanks to ultra-low internal resistance and maintain reliable performance across extreme temperatures, from -20°C to 60°C .Furthermore, they are up to 73% lighter than lead-acid batteries and contain no toxic lead or acids, making them a more environmentally friendly choice .
Compatible with over 95% of vehicles, sodium-ion start-stop batteries are a commercially available, drop-in replacement that reduces long-term costs and enhances vehicle efficiency.

7.5kgA sodium-ion start-stop battery is an advanced power source designed for vehicles with automatic engine start-stop systems. Unlike traditional lead-acid batteries (EFB/AGM), it uses sodium ions to store and release energy, offering superior performance and sustainability.
One of its biggest advantages is excellent cold-weather performance, retaining about 90% of usable power at -20°C for reliable winter starts. It also withstands high engine bay temperatures up to 60°C without rapid degradation. With a lifespan of 2,000 to 4,000 cycles, it lasts roughly three times longer than conventional batteries, reducing replacement frequency.
Sodium-ion batteries support ultra-fast charging and deliver higher starting power. They are also eco-friendly, containing no toxic lead or acid, and are inherently safer with a low risk of fire.

Product Advantages
Superior Cold-Weather Performance: Unlike traditional lead-acid options, a sodium-ion car starting battery retains approximately 90% of its usable power at -40°C. This ensures reliable engine ignition even in extreme winter conditions, outperforming many standard battery for autos.
Exceptional Longevity: Designed to handle 2,000 to 4,000 charge cycles, a sodium-ion unit lasts about three times longer than a standard AGM start stop battery. This durability means fewer replacements over the vehicle's life, offering a significant advantage over conventional options.
Enhanced Safety and Sustainability: Sodium-ion chemistry is inherently safer with a very low risk of thermal runaway, making it a stable choice for under-hood applications. It is also an eco-friendly alternative, containing no toxic lead or acid, which is increasingly important for manufacturers looking to standardize sustainable materials across their lineup, from a standard car starting battery to an electric car battery.
Rapid Recharging Capability: These batteries support ultra-fast 1C charging, meaning they can reach full capacity significantly faster than lead-acid alternatives. This ensures the start stop battery is always ready for the next engine restart, especially in stop-and-go traffic.
High Heat Resistance: Sodium-ion batteries are built to withstand continuous operation in high engine bay temperatures (up to 80°C). While an electric car battery requires complex thermal management, sodium-ion units handle heat naturally, ensuring reliable performance in hot climates without rapid degradation.
