| titleOfInvention | Analysis method for crack rate of electrode active material of electrode for lithium secondary battery |
| abstract | Provided is an analysis method for a crack rate of an electrode active material of an electrode for a lithium secondary battery. The analysis method is an analysis method for quantifying a degree of cracking of an electrode active material, and includes a first step of forming an electrode including an electrode active material, a binder, and a conductive material, a second step of visualizing material regions including the electrode active material, the binder, and the conductive material which are included in the electrode, and a pore region by impregnating the electrode with a resin, a third step of forming an electrode cross-section sample by cutting the electrode, a fourth step of obtaining a cross-sectional image by primarily photographing a cross section of the electrode cross-section sample, a fourth-first step of extracting total surface area pixels of the electrode active material by performing primary image processing on the cross-sectional image, a fourth-second step of extracting total boundary pixels of the electrode active material by performing secondary image processing on the cross-sectional image, and a fifth step of calculating a crack rate of an electrode active material of the electrode in the cross-sectional image using Equation 1 below. A crack rate % of an electrode active material = total surface area pixels of the electrode active material which are extracted from a first cross − sectional image / total boundary pixels of the electrode active material which are extracted from a second cross − sectional image × 100 . |
