New energy battery preparation method based on temperature monitoring

The invention relates to the technical field of battery pack preparation, in particular to a new energy battery preparation method based on temperature monitoring, which comprises the following steps: coating and drying a battery core pole piece; rolling the battery core pole piece, and detecting the temperature of the rolled pole piece so as to monitor the thickness of the rolled pole piece; stamping and shaping the battery core shell, and detecting the temperature of the stamped shell so as to monitor the quality of the stamped shell through the temperature; putting a battery core pole piece into the battery core shell, and sealing and forming the shell; and carrying out charging and discharging test on the battery cores, and respectively measuring the temperature of each battery core so as to carry out capacity grading on the battery according to the temperature. According to the method, qualified products of the new energy batteries are selected in a temperature measurement mode through the steps of pole
