Very often there is information on the web about one or another smartphone with battery exploded , and after publicity given only tiny fraction of cases. Most users prefer to quietly solve the problem through a service center, a fire or explosion if not spoiled property and did not cause injuries.
Such high flammability of lithium batteries are required combustible electrolyte , it was his problem and decided to U.S. researchers .
Scientists from the University of North Carolina say that thanks to the open research they managed to create the first non-flammable lithium-ion battery . They have achieved this by replacing flammable electrolyte long known of the technical lubricant perfluoropolyether (PFPE), which is used in the maritime business to cover hulls . This prevents them from sticking marine life and mud.
Scientists also have a suspicion about the useful side effect of replacing a hot item electrolyte PFPE. One of them , Joseph DeSimone (Joseph DeSimone), argues that a new type of battery can show a longer time at the same size and weight that conventional lithium-ion batteries . However, it still must be proved in further studies.
Scientists themselves have not yet even called approximate time of launching their batteries in series production. Before this new product must pass numerous inspections on toxicity, the effect of temperature factors and high / low atmospheric pressure , as well as counting the number of charge-discharge cycles . Only in case of a successful completion of all the tests battery can be said about its production.
Appreciate the importance of the work of scientists from the University of North Carolina can only be understood that the problem of ignition of lithium-ion batteries is beyond smartphones or laptops. Similar battery , only larger capacity are used in a variety of devices , even on airplanes . It is because of such batteries fire several times over the last year problems arose in the Boeing 787 Dreamliner, and the other aviasudov .
