According to newspaper reports: Gansu, China's first mobile phone battery explosion took place to cause a fatal accident. Mobile phone battery safety issues once again become a hot spot. Your cell phone battery secure? How to choose mobile phone battery? I have engaged in electric vehicle battery power system for research and development, access to the latest power batteries, battery electric vehicle safety has always been a key issue, and here I make some observations.
For now, cell phone batteries mainly for LION batteries (lithium-ion battery), parcels of liquid lithium-ion LIB, polymer lithium-ion battery LPB. Cathode material for lithium cobalt oxide. First, it is safe polymer Sony vgp-bps2c Battery cells, the absence of a hard metal shell packet, so even if an exception occurs, and both will not explode. Possible explosion is the main packet of liquid metal lithium-ion batteries.
Here with a packet of liquid metal lithium-ion battery safety analysis. In general, provided that they meet national standards, with regular national production license the product manufacturers, will not explode. The following reasons:
1) comply with the national standard batteries, require double-pipe above (over-voltage, over current, voltage, etc.) and safety of the whole protection circuit batteries. Even if short-circuit the battery electrode protection circuit will also be automatically disconnected, the output voltage to zero, will not explode.
2) Even if the protection circuit to remove, that is, even if the protection circuit failure, a direct short-circuit batteries, regular batteries in line with national standards, are safe aluminum batteries, short circuit, puncture caused by the intense reaction to cause the battery to release the internal gas pressure increases to a certain extent, the exhaust valve opens the exhaust, there will be no explosion.
3) Even if the exhaust valve has failed, and the soft aluminum will also be a result of internal pressure, bulging, rupture occurs up to a certain degree of mouth, diarrhea occurring gas, there will be no explosion.
So, with more than triple the protection case, we use the national standard Hp v6000 Battery, is safe. Only an accident in the battery (short circuit, high temperature, puncture), protection circuit failure, the battery batteries batteries are not safe (eg, steel core), safety valves and other special conditions also failed to have the same time, the case will it be possible explosion . So, no need to hear the explosion scared, I think the number of casualties in traffic accidents as far away as the battery explosion casualties of the million, million times more, should we not go out without Sheung do not drive it?
Battery, as long as the formal national standard battery manufacturers, no problem, but not necessarily original. With original equipment batteries objective technical indicators are not necessarily in practice better than the compatible battery, but no special technical gap is nothing but a number of original equipment batteries produced by a professional factory OEM batteries.
In this recommend several excellent domestic battery Brand: Hony Hp dv8000 Battery (online version, retail version), Scud batteries (Gold Commodities Business Edition, Green Power version)
