为何能快充？Why can be fast recharge？

1.双极板结构，电流密度非常均匀，充电效率更高；

Bipolar structure which makes the current density is very uniform and higher charge efficiency.

2.内阻降低70%，大电流充电发热小(根据电阻发热公式Q=I   *R*t，发热量随电流呈平方数增加)；

Internal resistance 70% decreased compare to traditional battery ,which generates much lower heat during   high current charging process(according to the resistance heating formula q = I   * R* t, the heat value increases in square with the current).

3.内部导电截面积是普通电池的3倍，可承受更大电流而不发热，且压降更小；

The conductive cross section area is around 3 times of traditional which makes it can withstands much higher charge current.
