AI Technical Summary
In the prior art, methods for evaluating the lithium ion transmission performance during the preparation of all-solid-state batteries may only be applicable to laboratory conditions and are susceptible to external interference in actual applications, resulting in the applicability of the evaluation method being affected.
By obtaining battery environment data, electrolyte state data and lithium ion state data, comprehensive analysis is used to obtain the battery environment adaptability evaluation value and lithium ion performance index threshold. Combining the lithium ion state evaluation value and electrolyte impact index, the lithium ion performance index is calculated, and the evaluation and feedback is carried out based on its comparison with the threshold.
It improves the universality and accuracy of the evaluation method, can more comprehensively reflect the lithium ion transmission situation of the battery during the active preparation process, promptly detect abnormal performance or downward trends, and achieve refined management and optimization of battery performance.
