subject: mobile phone battery explosion accidents occur frequently [print this page] Recently, mobile phone battery explosion accidents occur frequently, quickly became a major focus of consumer concern. Meanwhile, throughout the sampling results also show that the passing rate of mobile phone batteries generally low. On the cell phone batteries and other related issues, the reporter interviewed the Ministry of Industry and Telecommunications Research Institute laboratory He Guili Director Ter.

Mobile phone battery explosion caused by the batteries
According to reports, mainly by mobile phone batteries batteries, safety control circuit and the package of three parts. One of the most important part is batteries, which is the electrical energy storage device, when there is overcharge, over discharge, etc., there may be breakdown in low-quality battery core membrane, so that the core of the positive and negative electrical short circuit, easy to produce an explosion caused by high temperature and pressure.
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.

"Do not believe the ad in the large-capacity battery, the battery capacity and size of the current technology level is very difficult to achieve small size, large capacity." He Guili, reminds consumers that "consumers identify counterfeit batteries is not high must go to regular stores. "
Unified standard mobile phone battery differences
Previously, Ter Laboratory has proposed to establish uniform standards for mobile phone batteries. It is understood that the standard is currently under development and have had no specific timetable for release.

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.
