Abstract
Based on multiphysics numerical simulation and the principle of constant-current charge-discharge testing,a single-particle-size heterogeneous electrode model and a graded-particle-size heterogeneous electrode model for thermal-charging supercapacitors were established.The distributions of the electric field,concentration field,and temperature field were obtained.Furthermore,the effects of particle size and arrangement on ion heat/mass transfer and discharge performance were investigated.The results show that when the particle size of the active material in the electrode decreases from 15 μm to 5 μm,the rate performance improves and the discharge capacity increases.The arrangement of the heterogeneous electrodes significantly influences ion transport.For the same electrode thickness,the graded-particle-size design is more favorable for ion transport than the uniform-particle-size design.关键词
