    Battery aging leads to performance degradation, which affects the safety and lifespan of the battery. Therefore, it is very important to analyze battery aging. This paper performs Incremental Capacity Analysis (ICA) to analyze the degradation mechanisms (DM) of different lithium-ion batteries with varying cathode materials. ICA is utilized to analyze changes in peak height and area under the IC curve, which interprets key degradation modes such as Loss of Lithium Inventory (LLI) and Loss of Active Material (LAM). As a result of the experiment, the LCO battery lost less Lithium Inventory than the NCM batteries. In addition, it was analyzed that NCM battery is more resistant to aging than NCMA battery.
