摘要
以Ta_2O_5膜为绝缘介质作为钽阳极,以Ru O_2/Mn O_2/有序介孔碳作为阴极,制备了一种混合型超级电容器。该混合型超级电容器单元样品的电容值为6 m F,单元内阻为0.45?。对该类型的混合型超级电容器进行了热行为分析,并进行了相应的实验和仿真。同时在ANSYS中进行了有限元建模,分析其稳态温度分布。实验和仿真结果表明,在经过多次循环后,混合型超级电容器内部升温达到一定值,进入稳态。当充放电电流为5 A时,最高温度超过了50℃,需要采取一定的降温措施。
A kind of hybrid supercapacitor was prepared by tantalum anode and RuO2/MnO2/ordered mesoporous carbon cathode.The capacitance of the hybrid supercapacitor is6mF,and the resistance is0.45Ω.The thermal behavior of the hybrid supercapacitor was analyzed.Then the finite element model was built in ANSYS to analyze its steady temperature distribution.The experimental and simulation results show that,the internal temperature of the hybrid supercapacitor can’t reach steady state until rising to a certain temperature after several cycles.When the discharge current is5A,the maximum temperature exceeds50℃,and some cooling methods need to be takend.
