He Guili that, to prevent the above situation, qualified battery added to the composition of the safety control circuit to prevent short circuits. Meanwhile, the battery package, passing the battery will discharge within the pressure shell to set the device to prevent excessive pressure arising from expansion. In addition, shell materials, the vendor will use regular aluminum, this material is thin and there is some flexibility on the degree of pressure, while the counterfeit product is usually iron, low cost, once the explosion would cause great bodily harm sex.

He Guili that developed the original purpose of a unified standard mobile phone battery, the first to provide convenience for consumers; second update speed of mobile phones, each phone if the battery is different, will increase production costs; also can be extended phone and battery life of both products, saving on construction of social and environmental benefits are.
