It is understood that in the process of increasing the capacity and volume of lithium-ion batteries for smart phones, the conversion of electrochemical and chemical energy into heat is the main cause of safety hazards in lithium batteries, especially in the "thermal shock" project. When the test temperature rises to a certain temperature, it will cause a short circuit phenomenon in which the separation membrane melts and shrinks, and an energy conversion that is unexpectedly unexpected is generated. Under the test conditions stipulated by the mandatory standard, the larger the capacity of the lithium battery, the internal short circuit occurs. The higher the chance, the more likely it is to have security problems. The Nanjing Inspection and Quarantine Bureau reminded the public that consumers of smartphones, in particular, should reduce the blind pursuit of large-capacity lithium batteries when choosing mobile phone batteries, and try to choose mature products of regular brands. At the same time, avoid using the smartphone in an environment with excessive temperature and in the event of heavy impacts and collisions to avoid accidents.

Large-capacity batteries are increasingly sought after in the era of smart phones, but the staff of the Nanjing Inspection and Quarantine Bureau told reporters yesterday that they found in the battery battery inspection supervision that some large-capacity lithium batteries are in thermal shock according to the relevant mandatory standards . Heavy-weight mobile phone batteries and other safety items still have certain safety hazards.
