The performance and functionality of mobile phones have become more powerful after entering the smart age, but in stark contrast to the rapid development of battery technology. In addition to the battery life, which is plaguing smartphone users, there are still security issues. Although the number of cell phone battery detonation incidents reported by the media is not large, each one will cause people to worry about.
Researchers from the University of North Carolina at Chapel Hill are now working on finding safer battery materials that have already begun to take off.
According to foreign media reports, researchers at Chapel Hill recently discovered through experimentation that perfluoropolyether (a kind of fluoropolymer, abbreviated as PFPE) that is being widely used for large-scale mechanical lubrication and prevention of marine bio-adsorption has existing lithium batteries. Electrolyte-like chemical structure.
So researchers tried to use PFPE as a new battery electrolyte instead of the lithium salt solvent that has been identified as the detonation of lithium batteries.
The test results are exciting. The lithium battery with PFPE material has better stability, the chance of deflagration is almost zero, and it will not prevent the normal chemical reaction inside the battery.
In the next step, researchers will conduct more in-depth exploration on the basis of existing methods to find ways to further optimize the efficiency of chemical reactions within the battery.
At the same time, the researchers also stated that because PFPE has good low temperature resistance, batteries made from this material will be equally suitable for deep sea and aviation equipment.
