Lithium-ion battery is a complex thermoelectric coupling system, which has complicated internal reactions. It is difficult to investigate the aging mechanism due to the lack of direct observation of side reaction. I. ••The OCV model is established based on full cell SOC and electrode. ai Active area of the plateALAMi Pre-exponential factors of LAMi modelALLI. 1.1. Motivation and challengesAs a clean energy storage device, the lithium-ion battery has the advantages of high energy density, low self-discharge rate, and long se. 2.1. Test benchIn order to investigate the battery aging mechanism, the full battery aging experiment and half battery experiments are carried out. T. 3.1. Analysis of aging mode based on OCV curveTo identify the aging mechanism of the battery by using the OCV curve of electrodes, it is n.
