円筒型リチウムイオン二次電池内温度・電流分布の簡易発熱モデルを用いた2次元解析 Two-Dimensional Temperature and Current Analysis of Cylindrical Lithium-Ion Secondary Battery Using Simple Heat Generation Model
To develop large-sized lithium-ion secondary batteries for electric vehicles etc., it is necessary to take temperature and current distributions in the batteries into consideration. To make clear these distributions, the authors develop a two-dimensional time-dependent simulation code of temperature and current distributions during discharge cycles in cylindrical lithium-ion secondary batteries. The code is handy but sufficiently accurate because it uses the simple heat generation model recently established by the authors. Numerical simulations are, at first, performed for a commercially available small-sized battery, and accuracy of the code is confirmed through the comparison between the calculation results and the corresponding experimental results. Calculations are also performed for a large-sized battery and it is made clear that the temperature and current distributions become fairly inhomogeneous, indicating the necessity of the developed code.
