The monolithic cylindrical Li-ion battery, measuring 360 × 50mm (length × diameter), possesses the following electrochemical specifications: voltage of 3.7 V and a capacity of 40 Ah. It was disassembled for the purpose of researching electrode materials. Advanced materials analysis techniques, such as scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), and inductively coupled plasma mass spectrometry (ICP MS), were employed to ascertain the composition, morphology, and structure of the electrode materials. The analytical findings indicate that the positive electrode comprises an active material primarily composed of Lithium Cobalt Oxide, along with additives coated on an aluminum (Al) foil with a thickness of 25 micrometers. The primary constituent of the negative active material is graphite, coated on copper (Cu) foil with a thickness of 20 micrometers.
