This study focuses on the 46-series cylindrical lithium-ion battery to investigate its thermal behavior characteristics under adiabatic conditions. Utilizing an adiabatic environment constructed with an Accelerating Rate Calorimetry(ARC) apparatus, constant-current charge-discharge tests at 1/3 C were conducted on three different sizes and material systems of 46-series cylindrical batteries from the same manufacturer. Through systematic monitoring and analysis of the thermal effects during the charge-discharge processes, this research highlights the temperature rise characteristics and heat generation patterns of batteries with varying sizes and material systems under adiabatic conditions. The findings offer valuable insights for the thermal management of 46-series cylindrical lithium-ion batteries in future applications.
