Developing un-exploded Lithium Battery for Cellphone
After entering the intelligent era, mobile phones have become more and more powerful in performance and functions, but in sharp contrast is the rapid development of battery technology. In addition to the lack of battery life, there are also safety issues that bother smartphone users. Although the number of mobile phone battery explosion incidents that have been reported by the media is not many, each one will cause people to worry.
Lithium Battery fire
Now, researchers from the University of North Carolina at Chapel Hill are looking for safer battery materials, and they have begun to pay off.
According to foreign media reports, researchers at Chapel Hill have recently discovered through experiments that perfluoropolyether (a fluoropolymer, referred to as PFPE), which is widely used for large-scale mechanical lubrication and to prevent marine organisms from adsorbing on the bottom of ships, has the same lithium ion as the existing lithium ion. The battery electrolyte has a similar chemical structure.
Lithium Battery life
So researchers tried to use PFPE to replace the lithium salt solvent that has been identified as the culprit of lithium-ion battery deflagration as a new battery electrolyte.
The test results are exciting. The lithium-ion battery using PFPE material has better stability, the probability of deflagration is almost zero, and the normal chemical reaction inside the battery will not be prevented.
In the next step, the researchers will conduct more in-depth exploration on the existing basis, looking for methods that can further optimize the efficiency of the internal chemical reaction of the battery.
At the same time, the researchers also said that because PFPE has good low temperature resistance, batteries made of this material in the future will also be suitable for deep sea and nautical equipment.
