2- Ionic cell continues powering LED panel after being bent.

Ionic cell produces no fire or flames while being cut (scissors short circuiting cell, thus LED turns off).

Conventional Battery

When a conventional lithium ion battery is punctured, the battery shorts and the temperature increases rapidly, causing the liquid electrolyte to decompose and the cell to expand and burst. As the reaction continues, the liquid electrolyte ignites and expels flames and toxic gas from the battery. These thermal events have occurred in recent widely publicized incidents involving smart phones, toys, electric vehicles, and aircrafts.

Ionic Materials Solid State Battery

A key advantage to Ionic’s solid state batteries is that they are inherently safe. In this video, we show the destruction of a 5.5 Watt-hour Ionic Materials battery as it powers an iPad which has had its original battery removed. Ionic’s battery is made with a lithium metal anode, an LCO cathode, and Ionic’s solid polymer electrolyte. It remains very safe, without smoking, flaming, or exploding even after being impaled by a screwdriver and then cut in half with a paper cutter (both of which result in a direct short circuit that causes the iPad to turn off).  Even more, the battery continues to power the iPad after this abuse. This remarkable achievement is only made possible by Ionic’s solid electrolyte
