1. Superior Safety: According to the research of the Jerry Barker team of Faradion UK, The Sodium-ion batteries can actually be safely discharged to 0 V (true 0% SOC). Which can obviously reduce the danger probability of the battery during transportation and storage.
2. Versatile Solutions: Whether you need individual battery cells or custom battery packs, our Sodium-on Batteries can cater to you diverse needs,enhancing your product lineup.
3. Cutting-Edge Technology: Embrace the future with our state-of-the-art Sodium-on Batteries, delivering superior performance efficiency,and longer lifespan compared to conventional options.
4. Environmentally friendly: There nearly no heavy metal elements can pollute the environment, Sodium ion battery is completely safe and environmentally friendly. We can foresee that sodium-ion batteries will become sustainable low-cost alternatives to lithium-ion batteries for all kinds applications. Such as low speed electric vehicles and large-scale energy storage (ESS). Increasingly shifting to wind, solar and hydropower, they rely on battery energy storage for uninterrupted, all-weather performance.

7. Transport
Battery transportation state of charge is 30% ~ 50% SOC, the battery is packed into a box for transportation, in the process of
transportation should prevent severe vibration, impact or extrusion, to prevent sun and rain, must not be inverted.
In the process of loading and unloading, the product should be handled lightly to prevent falling, tumbling and heavy pressure.
8. Storage
Long-term storage of batteries for more than 6 months must be placed in a dry, ventilated place, storage state of charge of 20% ~
50% SOC, and every 6 months to carry out a charge and discharge cycle of the battery
