For today's Oriental Morning Post, "three kinds of mobile phone and laptop battery explosion hazard potential," the report, the parties Hp 346970-001 battery Amoi response to this was mainly due to lithium batteries and nickel-metal hydride batteries previously not the same testing standards caused and called for a new version of the national testing standards as soon as possible . According to reports, Amoi production model № .4 +3.7 V1150mAh lithium-ion batteries at 150 ℃ and thermal shock test failure.
It is understood that this sampling criteria used in the enactment in 2000 GB / T 18287-2000 "cell phone use lithium-ion battery general norm", because of the widespread use of mobile phone and laptops is the nickel-metal hydride batteries and nickel-cadmium batteries, lithium-ion the battery Hp HSTNN-DB02 battery has not yet been widely adopted, so the standard lithium-ion battery developed mainly in terms of testing the direct extension of nickel-metal hydride batteries and nickel-cadmium batteries, including "heat shock test the temperature of the standard 150 ℃, maintained for 30 minutes."
The past two years as handsets become more powerful, the battery capacity is also growing demand, the industry began widespread use of bigger, longer life lithium-ion batteries. But so far, the state authorities have not promulgated a new lithium-ion batteries for the national testing standards. 150 ℃ and the use of lithium batteries as a heat shock temperature standards, which has been a multi-party disputes. This is mainly because in 2000 when the Chinese mobile phone and laptop market, lithium battery capacity is very small, low energy density, 150 ℃ of the standard is no problem, but with the constant development of multi-function mobile phone and laptops and users of the stand-by time requirements, mobile phone and laptop batteries capacity of bigger and bigger, high-capacity battery can not withstand 150 ℃ standards, Hp HSTNN-UB02 battery in particular, more than 1000 milliamperes of high-capacity battery can only be 130 ℃ experiments, so the industry's 150 ℃ or 130 ℃ for the standard has been controversial for many years.
In 2003, the Ministry of Information Industry issued the implementation of YD1268-2003 "mobile phone and laptops and lithium batteries and charger safety requirements and test methods", in which the temperature of thermal shock test standards have been changed to 130 ℃, become the mobile phone and laptop industry, the industry generally Test standards; in September 2005 by the State Administration of Quality Supervision, Inspection and Quarantine and the National Standardization Technical Committee alkaline battery under the auspices of the national standard revision meeting, the proposed new national standard, "revised edition", in which the temperature of thermal shock test standards Hp DP390A battery change 130 ℃, but for various reasons, is expected in September 2005 promulgated a new national standard still has not issued. It is noteworthy that since 2004, in the UL, CE and other international certification standards for electronic products, the thermal shock test of the standard temperature, have also changed to 130 ℃.
Amoi specifically stated: Amoi procurement of lithium-ion batteries in strict accordance with prevailing standards in these industries are tested at 130 ℃ thermal shock test all qualified, including the tests involved in the № .4 + 3.7V1150mAh battery. Amoi customized for overseas operators are also produced by mobile phone and laptops are used after passing the standard test battery, the quality to be widely recognized by overseas operators.
At present, both the battery manufacturer or the mobile phone and laptop manufacturers in general would be 130 ℃ as a lithium-ion battery temperature of the thermal shock test standards, and in the battery design, production, quality control, procurement and other areas commonly used by this standard. Several domestic and foreign battery Compaq PP2100 battery makers are only committed to do 130 ℃, 130 ℃ has become a lithium-ion battery thermal shock test temperature of the de facto standard.
It is understood that thermal shock test is to place the battery hot-box in order to (5 ℃ ± 2 ℃) / min rate up to 150 ℃ ± 2 ℃ and heat for 30 minutes, the battery should not burst into flames, or leakage. This is a simulation of destructive testing under extreme conditions, in fact, when consumers use of mobile phone and laptops is difficult to encounter such a use of the environment, even 130 ℃, has also been far beyond the daily use of mobile phone and laptops to consumers when temperature limit. In Amoi and other major brand original mobile phone and laptop batteries, have a very eye-catching captions to remind consumers not to the battery into fire or heating in order to avoid an explosion.
In addition to the standard temperature of thermal shock tests, the 2000 version of the mobile phone and laptop batteries Compaq Presario R3000 battery(Compaq r3000 battery) in the old national standard specification for several other standards are the industry's multi-party disputes, when after seven years, the new timing of the national testing standards in the end, the industry waiting for
