Over 10 years experience in researching & manufacturing experience for the sodium ion battery industry.
What is Sodium Ion Battery
A sodium-ion battery, a new battery technology, by using sodium ions (Na⁺) as the energy carrier, which has a same working principle as a lithium-ion cell. However, it has an outstanding advantages in terms of the cost & availability of raw materials, safety, life cycling and a wider range of temperature application.
As end-users become more informed, they have set new expectations for battery safety, service life, and driving range. Lead-acid batteries are cheap, but they are environmentally unfriendly and lag behind LiFePO₄ and NCM 5-series/8-series cells in both cycle life and mileage. Lithium-ion technology, constrained by scarce resources and high material costs, has priced itself out of the price-sensitive segment.
Sodium-ion battery offers better intrinsic safety than LiFePO₄, costs less, and outperforms lead-acid in range and charge time, making it an ideal power source for micro-vehicles,residential energy-storage systems and utility-scaled battery energy storage system.
To meet this market need, we launched its “Sodium-ion battery R&D Center” in 2020, building the technical team around alumni of Hefei University of Technology.
We are currently using two main routes for making sodium-ion battery:
- A nickel–iron–manganese based system (heavy-oxygen chemistry)
- A phosphate–sodium ferrous sulfite route
We are moving into mass production for this sodium ion battery: annual production capacity is projected to reach 20 GWh by the end of 2026; and under our long-term roadmap, scale to 300 GWh by 2030.
Applications of sodium ion battery

Advantages of using sodium ion battery
We think, Sodium-ion battery is absolutely the future of battery energy storage technology, which has six following advantages
- It is of a higher safety than lithium-ion battery; through our innovative solutions, making sure no fire during the whole operation time.
- A lower cost of raw materials, it would be at least 15% lower than the costs of using lithium-ion batteries and even lower as manufacturing technology upgrade in future.
- Dual-30 principle for temperature tolerance, which can be working properly, which means sodium ion battery can still charge or discharge efficiently under minus 30C, further to ensure its high DoD.
- dual-15 principle, which makes an energy storage system can work Safely & Stably without using a liquid cooling system, thus will increase 15% more space inside of a battery storage cabinet.
- Lighter in weight, it would be around 10% lighter , compared with a same rated capacity of a lithium-ion battery system. It would be much easier for the transportation & whole installation process.
- long term storage at 0 voltage, this would be free to ship the sodium-battery by railway system and other shipping facilities, thus will save your shipping cost dramatically and less paper work with your local government authorities.

5. Could you please give us more information about yout sodium ion battery its outstanding performance, thanks
Firsly, The necessity of using liquid cooling system for battery energy storage cabinet.
◦ Lithium batteries are sensitive to temperature, with a comfortable operating range of 25℃±10℃. When the temperature falls below 15℃, the electrolyte becomes viscous, making it difficult to discharge the battery and charge it. When the temperature rises above 35℃, it is prone to thermal failure. Therefore, liquid cooling systems are compulsory for lithium battery energy storage cabinets. As you know, sodium ion battery has a much wider temperature range. it is not necessary to use a liquid cooling system, thus it can save the space for liquid cooling system and its wiring system; and improve its conversion efficiency: As there is no need to consume the battery’s own power for liquid cooling system, the conversion efficiency has been increased from about 90% to around 95%; furthe to save your costs a lot overally : The liquid cooling system and its wiring system account for approximately 10% of the total cost.
On the contrary, Sodium batteries are insensitive to temperature, and can be charged and discharged normally without liquid cooling at around 0℃, maintaining a capacity of over 95%; at high temperatures of 35-50℃, they can discharge 98% of their capacity without using a liquid cooling. Let us see our testing result for an electrical vehicle.
• Vehicle and battery condition: The sample vehicle has been in use for over two years, which is equipped with a 60-volt 70-ampere-hour sodium ion battery with a capacity of 4 kWh.
◦ Energy density: approximately 150 Wh/kg, which is about three times that of lead-acid batteries, and it occupies a small space.
◦ Price is approximately 0.1 USD per watt-hour, similar to the price of lithium iron battery.
◦ Lifespan and Degradation: After more than two years of use, there is essentially no degradation. With one charge and one discharge per day, it can be cycled over 3,000 times, boasting a lifespan of up to ten years. Even if the car breaks down, the battery still can be used. and testing temperature is zero centi degree (Celsius); and the battery remained the same perforamcne without any failure.
