Detection of lithium batteries

Shape detection: widening, thickness, TTV, verticality, warpage and chamfer.

Electrical performance testing: including conductive type, resistivity and minority carrier lifetime.

Appearance detection: crack (infrared flaw detection), crack, perforation, microcrystalline, line mark, crystal detachment, edge collapse and angle missing.

Impurity analysis: impurity oxygen and carbon content analysis.

In addition, if we do not have professional tools to judge whether lithium batteries are good or bad, then it is recommended to look at the product label, if the label is older, then this is not a good quality product, so, choose products to see the brand.
