    Nail Penetration Test Apparatus

  • detailed description
  • Description:

    The test should be carried out under the ambient temperature coupler with a thermocouple battery (the contact of thermoelectric is fixed on the large surface of the battery) is placed in a fume hood. Use a ф2-ф8mm non-corrosion steel needle to pierce the center of the largest surface of the battery at a speed of 10mm/s-40mm/s, and keep it for random time.

    What happens when you puncture a bloated battery?

    Yes. A swollen lithium-ion battery can be extremely dangerous if left in your device. It could become punctured, causing hazardous gases to escape.

     A swollen cell phone battery could even catch fire or explode while you're holding it, leading to serious injury.

    What is the nail penetration test?

    Explanation. Nail penetration test is a method of forced internal short circuit testing, simulating a short circuit that causes the battery to generate heat or fire. 

    In the test, a nail is inserted from outside into the battery charged to a charge depth of 100%, to forcefully generate a short circuit within the battery.
