It is a completely new battery technology and is poised to be a key technology of the future. Through decades of dedicated R&D, the VTCBATT team is already a pioneer in the polyanion system of Na-Ion Batteries, achieving maximum safety and energy density. Now, we have entered the stage of commercial production for Na-Ion batteries.
Different Applications Of VTCBATT Na-ion Batteries
Electric two-wheelersSodium-ion batteries are rapidly replacing lead-acid batteries and some lithium iron phosphate batteries due to their good low-temperature performance, high safety, and low cost.
Short-distance electric vehiclesSodium batteries can significantly improve the cost-effectiveness of A00-class passenger cars, low-speed electric vehicles, and logistics delivery vehicles, which do not require high energy density.
Household and portable energy storageIn the fields of household energy storage, portable energy storage, and UPS, sodium batteries have obvious safety and cost advantages, especially suitable for scenarios with medium cycle life requirements (about 2000-3000 times).
Base station and grid energy storageIn scenarios such as 5G base station backup power supply and grid frequency and peak regulation, sodium batteries can replace lead-acid batteries, adapt to a wide temperature range (-40~80℃), and have low maintenance costs.
Large-scale energy storage power stationsAlthough the cycle life is slightly lower than that of lithium batteries, the low cost of sodium batteries makes it potentially in large-scale energy storage power stations.
Industrial equipmentIndustrial vehicles such as electric forklifts and AGVs (automatic guided vehicles) are gradually adopting sodium batteries, taking into account both safety and economy.
Emerging applicationsIn 2025, sodium electricity will begin pilot testing in scenarios such as ship power and backup power, and may be expanded to more areas that are not sensitive to energy density in the future.
They have different advantages; you should choose them according to your application and budget. Here is their difference.
Energy density
Na-ion batteries: 100-160 Wh/kg (160 Wh/kg for CATL’s first-generation product).
Lithium-ion batteries: 250-300 Wh/kg (higher for ternary lithium).
Lithium batteries are more suitable for high-energy demand scenarios such as electric vehicles, while sodium batteries are mostly used for energy storage, low-speed vehicles, etc.
Material costs and resources
Sodium resources: 2.64% abundance in the Earth’s crust (only 0.006% for lithium), stable price (sodium carbonate is about 3,000 yuan/ton).
Lithium resources: Global reserves are concentrated (60% in the South American lithium triangle), and prices fluctuate greatly (lithium carbonate once reached 600,000 yuan/ton).
The material cost of sodium batteries is about 30% lower than that of lithium batteries.
Low temperature performance
Na-ion batteries: Capacity retention rate at -20°C > 88% (lithium batteries are generally <70%).
More suitable for application in cold northern regions.
Safety and lifespan
Na-ion battery: higher thermal runaway temperature (>200℃), not easy to catch fire; cycle life is about 3000 times (close to lithium iron phosphate).
Lithium battery: ternary lithium is prone to thermal runaway, lithium iron phosphate cycle life of>4000 times.
Technical details
Current collector: both positive and negative electrodes of the Na-ion battery can use aluminum foil (lithium battery negative electrode requires copper foil), further reducing costs.
Charge and discharge rate: na-ion desolvation ability is weaker than lithium, and fast charging performance is slightly inferior.
Yes, and they have many advantages over other rechargeable batteries:
Sodium-ion batteries have better fast charging performance than lithium-ion batteries. Their high ionic conductivity (20% higher than lithium-ion) and low electrolyte concentration requirements enable more efficient charge transfer. Some technical solutions even support ultra-fast charging in seconds.
Sodium-ion batteries can still maintain more than 85% capacity at low temperatures of -20°C, and their charging efficiency is significantly higher than that of lithium-ion batteries, making them suitable for use in cold areas.
Supports high-rate charging of more than 5C (i.e., full charge in 12 minutes); achieves 100% deep discharge without obvious loss, and a cycle life of 3000-4700 times; aluminum current collectors do not corrode at low potentials, improving fast charging safety.
The cost of raw materials is 30-50% lower than that of lithium-ion batteries, and sodium resources are evenly distributed globally, avoiding the geopolitical risks of lithium resources.
You are insightful. Na-ion batteries currently have great potential compared to other types:
Market growth prospects
The global Na-ion battery market is expected to grow from 2024 to 2034, with a compound annual growth rate of 26.1%. China plans to achieve a production capacity of 60GWh in 2025.
Technological breakthroughs and cost advantages
Fudan University has achieved an energy density of 239.4Wh/kg for sodium batteries through electrolyte optimization.
The cost of raw materials is 30-50% lower than that of lithium-ion batteries, and some companies have achieved a manufacturing cost of 0.3 yuan/Wh.
Expansion of application scenarios
Na batteries have advantages in fixed energy storage scenarios such as grid energy storage and base station backup power. China expects that the installed capacity of sodium-ion energy storage will be close to 50GWh in 2030, and the global energy storage demand will account for 40%.
It will first be applied to two-wheeled electric vehicles, and gradually expanded to low-speed electric vehicles and extended-range hybrid vehicles.
Policy and industry chain support
China has included sodium batteries in the key research and development direction of new energy storage technologies in the “14th Five-Year Plan”, and the Ministry of Industry and Information Technology has clarified its positioning as a supplement to lithium batteries.
China’s sodium battery cathode material production capacity is expected to reach 100,000 tons in 2025, and the construction of the global supply chain will accelerate to avoid geopolitical risks of lithium resources.
Challenges and responses
Although there are problems such as lower energy density than lithium batteries and the need to improve cycle life, it is expected to enter a period of rapid growth from 2025 to 2030 through technological iteration and large-scale production, and it is expected to replace 50% of the lithium iron phosphate battery market share in the future.
Therefore, as a leading Chinese company, VTCBATT is your best choice for customized lithium batteries.
