At the same charge condition, the larger mass ratio of positive and negative active materials is, the more gas produces, the higher internal pressure is.

相同的充电条件下，正极与负极的活性物质质量比越大，产生的气体越多，内压越高；

It was concluded that high internal pressure was caused by oxygen evolution of positive electrode and slow reducing rate of oxygen in negative electrode.

由此可以判定，内压升高的原因在于正极的析氧及负极氧还原速度的缓慢。

While taking advantage of the internal gas nozzle powerful "negative pressure" to achieve the gas nozzle cleaning, sand plug solve the problem.

同时利用气嘴内部强大的“负压差”来实现气嘴清洗，解决砂堵问题。
