英文摘要：

A modeling and simulation method was proposed for the LiMn2O4/C hybrid supercapacitor. The key pa-rameters of the model were identified with this method and were measured with various precise measuring methods so that avoiding the errors from assumption or parameter reference. Precise charge-discharge curves of a LiMn2O4/C hy-brid supercapacitor were obtained by simulation. Experimental verification proves that the charge-discharge curves from simulation and experiment fit well and the relative errors of the charge and discharge time are less than 5%. Fi-nally an MEMS hybrid supercapacitor with 3D-electrode structure was designed and the reaction mechanism inside its micro-electrode was studied using this method.
