Standardizing mechanical tests on li-ion batteries to develop a …
In our opinion, a more appropriate type of test should be four-point bending, which is also suggested by the ASTM standards [59], [60] as the battery cell belongs to a composite structure. Compared to three-point bending, the four-point test can introduce a larger deformation zone into the battery cell, which can avoid the effects of …
