Document Type and Number:
WIPO Patent Application WO/2024/080171
Kind Code:
A1
Abstract:
According to the present invention, the performance of a battery manufactured using carbon as a negative electrode active material is estimated with high accuracy from the physical properties of the carbon. A method for estimating the performance of a battery manufactured using carbon as a negative electrode active material from the physical properties of the carbon is characterized in that the performance of the battery is estimated using a machine learning model obtained on the basis of training data including the following physical properties (a) and (b) of carbon, and values related to the battery performance measured for the battery manufactured using the carbon as the negative electrode active material. (a) The ratio (ID/IG) of the peak top intensity (ID) of the D band calculated from the Raman spectrum to the peak top intensity (IG) of the G band or a value relating to the ratio (b) The width of the G band calculated from the Raman spectrum or a value relating to the width
