A recent study discovered a breakthrough in magnesium batteries that makes these energy devices safer, as reported by ScienceDaily.com.

Unlike the traditional lithium ion batteries, which had been making headlines because of explosion, magnesium batteries are not flammable or subject to exploding. However, their energy storage has been limited. (Related: Lithium polymer batteries likely replacement for dangerous lithium ion in laptops, says Sony.)

The researchers from the University of Houston discovered a new design for the battery cathode — the electrode from which the current flows — that drastically increased the storage capacity and upending conventional wisdom that the magnesium-chloride bond must be broken before inserting magnesium into the host. The study was published in Nature Communications.
