Customer ServiceNail penetration is one of the most critical scenarios for a lithium-ion cell: it involves the superposition of electrical, thermal and mechanical abusive loads. When an electrically conductive nail is introduced into the active layers of a lithium-ion cell, an electric short circuit takes place between the conductive components (electrodes and current collectors).
Customer ServiceThe 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.
Customer ServiceSealing nail welding is an important process to achieve complete isolation between the inside of the battery and the external environment.
