Why Choose Sodium? Sodium Battery VS. Lithium Battery

Good Safety Performance
Sodium batteries will not catch fire or explode when overcharged, overdischarged, short-circuited, dropped, squeezed, punctured, impacted by heavy objects, or heated.

Good Low Temperature Performance
Sodium batteries can be discharged at -40°C and charged at -20°C. It can replace lithium iron phosphate batteries in cold areas.

Excellent Rate Performance
The rate performance is better than that of lithium iron phosphate batteries and can be charged to 90% in 15 minutes.

Overdischarge Is Reversible
Sodium batteries allow over-discharge without affecting life and safety.

Linear Charge And Discharge Curve
More accurate SOC estimation reduces your anxiety about battery power or battery life

Lower Cost:
Abundant sodium resources and outstanding performance allow sodium batteries to achieve stable supply and continue to reduce costs. Compared with lithium iron phosphate batteries, they have lower costs.

Application Scenarios
