摘要: Abstract The thermal safety of lithium-ion battery is a serious issue in its applications. A pack cooled by cutting copper fiber sintered skeleton (CCFSS)/paraffin composite phase change material (PCM) designed and fabricated. effect the CCFSS/paraffin PCM on temperature investigated discharge experiments compared with natural air cooling, pure paraffin, foam/paraffin PCM. two-equation non-thermal equilibrium model using enthalpy method established. experimental results indicate that difference case paraffin exceeds 5 °C, while effectively enhances heat transfer performance maintains differences within 5 °C. numerical show good agreement data, validating accuracy model. Therefore, effects key parameters are predicted via heating rate decreases increases number pores per linear inch (PPI) convective coefficient. With increase spacing between cells, duration increases. This work provided reference for application dissipation batteries.
