Nail Penetration Test is an internal short circuit testing method that tests the safety of lithium-ion batteries to withstand internal short circuits. Use steel nails to penetrate the battery, simulate an internal short circuit, and conduct a test to confirm if the battery is smoking, catching fire, or breaking.
The nail test was originally designed to replicate a cell failure caused by a piece of rogue metal that gets into the cell during production. The metal nail causes a short circuit between the active layers and hence rapid electrical heating. This is one of the most severe cell tests and part of a suite of abuse tests.
