Samsung to send mobile phone explosion event battery quality worries

Mobile phone charge explosion has been a common occurrence, many of the main cause of spontaneous combustion of lithium batteries is too long charging time and did not use the regular brand of mobile phone charger, resulting in the lithium battery under special uncertainties into a latent "grenade", at all times threatens the personal safety of mobile phone users. Recently, the famous foreign social news site Reddit exposure, a Samsung Galaxy S3 user in the mobile phone charging process suddenly spontaneous combustion, the whole battery has been fully expanded, the phone shell and fuselage also left a clear burn marks, the bed sheets were burned a hole, the whole second floor is full of smelly smell. Luckily, there were no significant casualties and property damage, and the main finger was slightly injured. In fact, in the past, the spontaneous combustion of mobile phone incidents have occurred many, heavy aircraft destroyed, light mobile phone scrap. Just as in July 07, Guangdong, the country's first mobile phone battery explosion caused the death, a 22-year-old youth in the work, because of the chest hanging mobile phone suddenly caused by a sudden explosion of chest was hit, ending the young life. And not long ago, Xiamen's Yu is sleeping, because mobile phone alarm rang she conveniently press off and put back to the bedside table, unexpectedly suddenly bang a sound, mobile phone bounce half meters high, the fuselage was blown up, the battery fell on the wood floor burned up and smoke, frighten Yu shout family help and slippers Pat. She said the phone was a net purchase she had just bought a year ago, and did not expect such a scary thing. Looking at many of these phone bombings, summed up the main causes of cell phone explosion is two: 1. Battery quality problem: Counterfeit defective lithium battery is caused by many lithium battery explosion, many of the fake lithium batteries due to excessive raw material impurities, production process unqualified, battery safety protection related design is not in place. 2. The battery does not have the security protection: in the long time charging state, the electric current is too big, the voltage is too big, the power source excessively heats up causes the handset not to use normally. and lithium batteries in special temperature, humidity and poor contact conditions may be instantaneous discharge and generate a large number of current, triggering spontaneous combustion or explosion. The normal lithium battery in the manufacture of the battery in the amount of debris and the size of the strict control, at the same time, the regular manufacturer of lithium batteries, shell used flame-retardant materials, so the quality of the Li-ion battery in the normal use of the process is not easy to explode. And some jerry-made manufacturers in order to profiteering will be on the raw materials, leading to the production of the battery can not reach the standard, for the mobile phone accident buried the curse. As the domestic first-line battery brand manufacturers, long Tatsu group, they began to focus on battery development since 1979, senior battery experts have been 33 years of research and development of battery experience, Rhonda is not only China's core standards will be members, but also with the Harbin Institute of Technology to maintain long-term scientific cooperation. They have advanced research and development team, made of a type of batteries, products have been a number of products to obtain a national patent, with lithium battery explosion-proof helmet exclusive patented technology. With four security protection (short-circuit, overvoltage, over-current, overheating), quality and reliable. BrownSenior battery experts believe that the cause of mobile phone explosion is not only the quality of the product itself, human factors also exist. To this end, Lang Tatsu experts recommend: 1. Avoid buying shoddy cell phone batteries or mobile phone chargers, must buy the original production of batteries or formal brand manufacturers to produce mobile phone chargers, not to greed for small and cheap to brew the curse. 2. Do not charge under low temperature or high temperature condition. At a low temperature of 0 degrees Celsius, the charge will be significantly lower than the normal amount of electricity, which leads to the negative and positive reaction is not sufficient, resulting in excess lithium ions formed crystal precipitation, resulting in the diaphragm is pierced, so that the battery inside a short circuit triggered an explosion. 3. Do not charge for a long time, and do not put the mobile phone in the heat-resistant place, now the big screen mobile phone is very easy to power consumption, many people are accustomed to hiding in the quilt charging side play mobile phone, so there is a great danger. 4. It is best not to recharge the phone when thunder and lightning strikes, lest the phone be electrocuted by lightning or cause an artificial shock.
