Product Name:
New Product 40225 3V 15Ah Cylindrical Sodium Ion Battery Cell
Highlights
Compared with LiFePO4 battery/ Lithium iron phosphate batteries，the Soduim ion batteries are:
- Energy density: 100-130Wh/kg
- Fast charging: 80% can be charged within 15 minutes of normal charging, more than 95% of the rated capacity can be charged within 20 minutes
- Long life: cycle life 1000-5000 times
- Safety: no combustion, no explosion, it is a safe and reliable battery product
- Wide temperature range: -20°C to 90°C works normally without explosion.
- Low cost: the same power unit, the cost of sodium battery is only 2/3 of that of lithium battery
