Lithium Ion Battery More Energy and More Secure
A Solid Lithium-Ion Batteries are fully MIT scientists developed with many outstanding features. Lithium-ion battery in your phone at first glance like a solid block of plastic, but if you open it up and look closer, you will see there is some liquid inside. That’s because most lithium-ion batteries made from many different components: two electrodes separated from each other by solid polymer membrane and a liquid electrolyte or gel.

Currently, MIT scientists were the first countries in the development of lithium-ion batteries completely solid. Basically, this type of battery has the capacity to store more energy, which means that you are not plugged regularly for your device again. Frank McGrogan and Tushar Swamy and co-author of the study. They studied the mechanism of action of lithium sulfide which someday will probably replace the liquid electrolyte in lithium batteries because of its current stability and firmer. Switching between the liquid electrolyte and solid can be a big step. Full solid batteries can store more energy, and less likely to cause more problems.
The team did consider the toughness of sulfide – a characteristic necessary for the role of materials used in lithium-ion batteries. If it is too brittle and can not withstand the constant pressure, it may crack, causing leakage and other battery issues.

This study also faced a significant hurdle: sulfide is a very sensitive matter for the room conditions and can not be brought to trial in the air. For testing, the team put in a tank sulfide mineral oil to prevent it reacted before checking its mechanical properties. This is the first experiment to test the brittleness (fracture) of sulfide. After testing, the researchers concluded that this material does not crack under conditions of high pressure. This is the premise allows the team to go into production the new battery system. Of course, everything is just beginning and still a long way ahead to put entirely solid lithium batteries into use in practice.
