“…[17][18][19][20] In addition, in the process of the charge and discharge cycle, the collector surface is in contact with the electrolyte for a long time, and the micro decomposition product HF in the electrolyte will corrode the surface of the collector, resulting in the porosity and even separation between the collector and the active substances, and then the performance of the battery will decline. [21][22][23][24][25][26][27] In order to enhance the comprehensive characteristics of a Cu foil collector, efforts have been tried to address these problems, such as surface mechanical attrition treatment, [28][29][30] growing graphene or depositing Au nanoparticles or embedding Si negative particles, [31][32][33][34][35][36] surface roughening and surface nanopore treatment, [37][38][39][40][41] and ultrasonic surface rolling processing (USRP) technology, 42,43 which provided new ideas for the development of a high behavior collector in lithium ion batteries.…”
