▎ 摘  要

NOVELTY - Method for evaluating electric core compaction system involves assembling positive pole pieces with different compacted densities and negative pole pieces with different compacted densities into electric core, performing electrochemical impedance test to electric core, and determining best compaction system of positive pole piece and negative pole piece according to result of electrochemical impedance test. USE - The method is used for evaluating electric core compaction system. ADVANTAGE - The method can quickly evaluate best compaction matching in electric core system by EIS test, does not need to test basic electric performance of electric core, and selects compaction density for electric core production design to provide guide direction.
