DEFORD unveils their NaPALION sodium-ion powersports batteries in August 2024.
After more than one year of development, DEFORD New Power Co., Ltd finally released their NaPALION sodium-ion powersports batteries in August 2024. NaPALION powersports batteries are based on sodium-ion battery technology. The launch of NaPALION powersports batteries will fundamentally change the landscape of the powersports battery market in the next few years.
Lead acid battery has been dominated the powersports battery market for more than one century. Lithium-ion battery is not good at cold-starting the engine and therefore cannot meet the requirements of starting batteries. Sodium-ion battery has excellent low-temperature discharge performance and can still keep high power even at -28 degrees Celsius. In terms of CCA performance, sodium-ion battery is even more advantageous than lead acid battery.
Lead acid battery should strictly avoid over-discharge to prevent irreversible loss on capacity. Whilst Sodium-ion battery is not afraid of over-discharge and can be discharged to 0V, there will be no loss of capacity after recharging. Lead-acid battery usually need to be charged every 3 months to keep the performance, while sodium-ion battery can extend the charging time to 12 months.
The abundance of sodium in the earth's crust is 2.3%, ranking sixth among all elements, significantly higher than 0.0017% of lithium. Sodium is widely found on land and in the ocean in the form of salt and is easy to obtain. Compared with lead-acid battery, sodium-ion battery is eco-friendly. Sodium-ion battery does not contain any heavy metals and are 100% recyclable.
The high conductivity of sodium ions requires a lower concentration of electrolyte. The viscosity of the electrolyte at low temperatures is lower than that of lithium-ion batteries, and the overall performance of the battery is better. The normal operating temperature range of sodium-ion batteries is -40℃-60℃, and the capacity retention rate at -20℃ can reach more than 85%, which is significantly better than the 60-70% capacity retention rate of lithium iron phosphate.
To help customers understand the differences between sodium-ion battery and lead-acid battery, the NA1209 is compared with a typical lead acid YTX20HL-BS battery as follows:
