Lithium Ion Battery Temperature Field Numerical Simulation Research

As a new type of lithium-ion energy should be in a wide range of industries , the battery 's own battery temperature is facing a serious problem . Based on the three-dimensional applications based on COMSOL MUTILPHYSICS software was simulated using the control variable method and compared the results of its analysis. Application of COMSOL MUTILPHYSICS software to simulate the three-dimensional basis, using control variable method, and the results were compared. The results show that, when the temperature is high or when the battery discharge times, rising temperatures in the region better, faster and more; heat of reaction generated; also get a cell center along the radial direction, the temperature is gradually reduced.
