Due to that reason, increasing of discharge power should be maintained to extend battery cycle life as well as to prevent battery failure. The high-temperature difference between the LIB surface and air gap during the discharging process indicated that there is required heat transfer enhancement.
The charging and discharging processes of the battery are optimized. The capacity degradation is unfavorable to the electrochemical performance and cycle life of lithium-ion batteries, but the systematic and comprehensive analysis of capacity loss mechanism, and the related improvement measures are still lacking.
The discharging step aimed to eliminate the remaining electric current to avoid the potential danger of explosion from a short-circuit or self-ignition of the battery when dismantled . Meanwhile, the dismantling process aimed to separate the battery components, consisting of the battery sleeve, anode, separator, and cathode sheets [3, 47].
DnCNN model is utilised to accurately calculate battery capacity and performance, and the performance is evaluated using mean squared error (MSE) and PSNR. The CNN-based training method employs the BFGS quasi-Newton algorithm to measure battery capacity accurately by evaluating the mean squared error (MSE) and regression results.
