Watch: Battery Safety testing and the U-M battery Lab

Don’t try this at home: This nail penetration test was designed as a control to show the violence of a catastrophic battery failure when not properly contained. This test was conducted for an external Battery Lab customer designing battery safety products. The automatic “nail” piercing the battery cell is one of a kind, and was designed by a collaborative team including the Battery Lab and Mechanical Engineering staff.
