The Stanford team added a "fire extinguisher" to the lithium battery.

Note 7 After a deflagration accident and eventually forced to completely stop production, various mobile phone manufacturers are paying more and more attention to equipment safety.

For example, LG has improved the inspection standards for its own mobile phone lithium batteries to ensure that they will not overheat and detonate, and in the new flagship G6 they also added heat pipes to help the battery to dissipate heat. However, the research team at Stanford University is ready to solve the problem of battery deflagration once and for all.

Recently, the research team at Stanford University announced a new type of lithium battery with a triphenyl phosphate capsule in its electrolyte. Once the internal temperature of the battery reaches 150 degrees Celsius, the capsule will dissolve and release triphenyl phosphate.

Triphenyl phosphate is a chemical flame retardant that, after testing by the team, extinguishes the deflagration caused by battery overheating in 0.4 seconds.

The triphenyl phosphate capsule warehouse is like adding a fire extinguisher to the battery. It is really important for a lithium battery that is often "moody" and that is easy to detonate when it is slightly wrong in manufacturing and use.
