Nail penetration test
Lithium-ion batteries and other secondary batteries are equipped with protective elements and protective circuits for safety. Nail penetration testing is a type of safety testing done to simulate internal short-circuiting. Along with nail penetration testing, ESPEC also provides a.

Battery Nail Penetration Test
The nail penetration test has been widely used across the battery industry and battery-user community to assess lithium-ion battery safety. The Relationship of.
Description:A successful model must be able to address the following critical aspects in order to truly describe the fundamental mechanisms underlying the nail penetration process in large-format Li-ion cells: The vertical, cylindrical penetration sample holder along with the horizontally fixated cell is depicted in Figure 1 upper figure. The objective is to determine the increase in pressure and temperature during penetration. This also validates the change to the more capable hydraulic system with its negligible sensitivity of velocity to cell thickness compared to the through the air nail velocity. Overcharge Durability evaluation for the overcharged state of assembled batteries Charge the battery with the current of twice the maximum continuous charging current recommended by the maker. Spotnitz also extended his model to simulate battery packs.
