1. Introduction. Lithium-ion batteries (LIBs) are widely used in portable electronic devices. With characteristics of high power density and little memorizing effect, LIBs are now also being utilized as the power source for electric-powered transportation tools, such as EVs (electric vehicles) and HEVs (hybrid electric vehicles) [1], [2].Since …
The core needs to be pressed into the glue nail after a liquid injection. If the glue nail is not pressed in place or skewed, it will lead to the risk of liquid leakage. Deep vision intelligent 3D camera can accurately and quickly detect the shape of glue nails, and 3D vision software with position correction function can avoid the influence of ...
Battery Sealing Strategies Hermetic epoxies seals protect lithium ion batteries Whether they take to the streets in electric vehicles or stand still in energy storage systems, lithium-based battery modules pose a tough challenge from a wire sealing standpoint. Modern battery modules have a variety of power and signal conductors
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 …

In this field, sealing nails play a vital role in the power battery of vehicles, and the industrial piece needs strict quality inspection according to its visual appearance …
Similarly, the Li 1s spectra of the lithium anode as shown in Fig. 3 c shows the peaks of Li 2 O 2 (54.4 eV) and Li 2 CO 3 (55.1 eV) [43], which is accord with the O 1s spectra. The reaction between air and lithium metal during nail penetration process should be responsible for the existence of Li 2 O 2 and Li 2 CO 3.
Internal short-circuit tests were carried out in a battery safety investigation chamber to determine the behavior of batteries during the nail penetration test. So far, systematic investigations regarding the test setup and its influence are rarely found in the literature. Especially, to improve the comparability of the multitude of available results, it is …
