手机动辄爆炸的消息让不少消费者惴惴不安,现代人的生活离不开手机,但如果有个“炸弹”在身边也着实令人难以安心。在手机电池检测中,有一项为电池热冲击检测,该检测将锂电池放入150℃烘箱,以每分钟5℃的速率提高温度,烘箱温度升至150℃,保持30分钟,看电池是否会发生爆炸。日常生活中,手机很少接触到150℃的温度环境。如果电池放置不当,比如接触钥匙、硬币等导电介质,可能使电池短路。当保护电路失效时,会在瞬间产生较大电流,使电池瞬间产生较
The frequent explosion of mobile phone news so many consumers uneasy, modern life can not be separated from the phone, but if there is a “bomb ” in the side also really difficult to feel relieved. In cell phone battery testing, there is a battery thermal shock testing, the test will be lithium batteries into the oven at 150 ℃, the rate of 5 ℃ per minute increase the temperature, the oven temperature rose to 150 ℃, for 30 minutes to see whether the battery will explosion occurs. In everyday life, mobile phones rarely touch the temperature environment of 150 ℃. If the battery is placed improperly, such as contact with keys, coins and other conductive media, the battery may short-circuit. When the protection circuit fails, it will generate a large current in an instant, so that the battery instantly produce more
