June 27, Guangzhou, sanyo battery there were two mobile phone explosion; Not long ago, close to Hefei, Luan also taken place with the mobile phone explosion – but perhaps shortly after, with the production of polymer lithium batteries in Hefei in the market control of the voice this kind of tragedy will not be repeated.
How to carry cell phones to explode it? Battery expert – Rongshida Li Jianguo, general manager of the new energy company told reporters that the current mobile phone batteries on the market, almost all lithium batteries, can be divided into liquid lithium sanyo db-l20 battery, lithium-polymer two categories, and more than 90% of the battery is liquid lithium, and the use of steel and aluminum shell. This liquid lithium batteries in over-charging, high temperature, collision and other extreme cases, might lead to short-circuit, once the short circuit, battery cell will be inside the organic electrolyte electrolysis and produce gas, and in severe break through the shell, exploded.
It is understood that production of polymer Rongshida is developing lithium batteries, the sanyo db-l40 battery using the flexible packaging, even if the internally generated gas, will only expand, or earlier breakthrough in the shell, avoiding the fierce explosion, thus more secure. “At present, Ministry of Information Industry is developing uniform standards for mobile phone batteries.” Hefei Economic and Trade Commission official said, with the introduction of battery standards, Hefei safety of batteries will produce in the market, “pre-emptive.”
TD mobile phone battery manufacturers is still plagued by problems caused by increasing power consumption application of multi -
In a recent TD-SCDMA Forum, relevant meetings sony battery, TCL Group, Industrial Technology Research Institute, vice president of Wang Kai-Long said the current development of TD terminals have to face many challenges, including TD mobile phone battery is still the key point.
He said, since the majority of 3G phones will be multimedia phone, and TD technology itself has the corresponding requirements for power sony np-bg1 battery, so power-hungry will make TD terminal batteries seem difficult to sustain, the battery power is a major problem.
Previously, TD mobile phone battery has been very concerned about the operators and users of the problem, once there is news that the technical difficulties TD mobile phone batteries have been basically solved.
According to the requirements of the relevant operators acer aspire 3000 battery, TD-SCDMA handsets in 2008 will enable videophone, mobile TV, location services, mobile Internet, 3C interconnection functions.
