Nowadays, many of us are glued to our phone screens, looking at them for hours on end. None of us expect that such a small electronic device could possibly be so dangerous.

However, in 2016, there were dozens of reports showing that Samsung's newly released Galaxy Note 7 gave off excessive amounts of heat, causing several phones to overheat and one even to explode—it was found that the lithium-ion batteries were to blame.

This prompted scientists to look for ways to make these batteries safer.  Since previous lithium-ion batteries are made with highly flammable and moisture-sensitive materials, alternatives are now being explored to deliver both better performance and increased safety.

Last 2017, a team of researchers from John Hopkins University, University of Maryland, and the Army Research Laboratory unveiled a breakthrough new lithium-ion battery. Their study was published in Advanced Materials.
