Why Switch to an 18650 Sodium Ion Battery?
Although Lithium-ion has dominated the market for years, the new 18650 sodium ion battery technology is rapidly emerging as a superior alternative for stationary storage and low-cost applications. Furthermore, since sodium is abundant and inexpensive compared to lithium, these cells become significantly more cost-effective in the long run.
In addition, safety is a major advantage. Unlike lithium cells, which can be dangerous if over-discharged, Sodium-ion cells can be discharged to 0V for safe transportation. For instance, you can safely transport them without hazardous material restrictions. For detailed comparisons on safety and chemistry, refer to scientific publications such as ScienceDirect's overview.
Performance in Extremes
Moreover, these batteries perform exceptionally well in cold temperatures where LFP and NMC chemistries often struggle. Consequently, they retain over 90% capacity even at -20°C. If you are looking for larger quantities for commercial projects, please check our bulk orders section.
Building Custom Packs
The versatility of the 18650 sodium ion battery allows for easy configuration into larger packs (e.g., 12V, 24V, 48V). Whether you are building storage for a solar project or an electric scooter, these cells offer a familiar form factor with updated chemistry.
Always use a compatible Sodium-ion BMS. Contact our engineering team if you need assistance selecting the right management system for your build.
Frequently Asked Questions
Can I use an 18650 sodium ion battery in my existing lithium device?
No, not directly. Since Sodium-ion cells typically have a lower nominal voltage (3.0V-3.1V) compared to Lithium-ion (3.6V-3.7V), they are not drop-in replacements. Therefore, you must ensure your device or BMS supports the sodium-ion voltage range.
Do I need a special BMS?
Yes, absolutely. Because the voltage curves are fundamentally different, you need a BMS specifically programmed for Sodium-ion chemistry. Otherwise, you risk overcharging or under-utilization.
