The advantage of high rate battery
Typical Structure：Winding and stack structure
Comprehensive and develop the winding and stack structures, and are progressively reduce unfavorable factors
Power characteristics of high rate batteries
Typical design for 40C cell
Continuous discharge：5000Wh/kg and 10000Wh/L
Pulse discharge： 8000Wh/kg and 16000Wh/L
| Cell structure | advantage | Advantage application | Disadvantage |
|---|---|---|---|
| Stack | Low resistance(parallel structure);High energy density | Supply smooth high voltage and high power,and battery is small volume and light in weight | The probability of internal short circuit is big,and the uniformity is bad. |
| winding | The risk of internal short circuit is low,and the uniformity is good. | The quality is reliable,and the rate of finished products is high. | High resistance(Series structure);the energy density is low 5%. |
