2. Main Features of Our EV Battery Cells
1. High energy density
| | lifepo4 battery cell | LiNiCoMn battery cell (ab.NCM battery) |
| weight energy density | 150wh/kg | 200wh/kg |
| volume energy density | 280wh/L | 334wh/L |
2. Low internal resistance
Methods of reducing the internal resistance:
**Using carbon coated aluminum foil
**Multiple electrode tab design
**Increasing the width of electrode tab
**Coating PVDF on battery separator
**Pore-creating artificially
3.Long lifespan
Usable for more than 2,000 charge-discharge cycles
> 4 times than lead acid battery
> 2 times than li ion battery
4.Excellent performance in high and low temprature
Usable in extremely cold and hot environments (-20 to 60 ºC)
