摘要
随着电动汽车、清洁能源存储的快速发展,开发与之相匹配的兼具高功率、高能量、长寿命的电化学储能器件成为目前的研究重点。超级电容器是一类重要的电能储存装置,具有功率密度高、温度特性好、循环寿命长等优势,但低的能量密度限制了其在规模储能领域中的进一步应用。如何在保持超级电容器高功率、长寿命的前提下提高其能量密度是当前亟待解决的问题。钠离子电池相比锂离子电池能量密度略低,但资源和成本优势使其在未来大规模储能应用中具有广阔的发展前景。钠离子电容器可以克服钠离子电池和超级电容器各自的性能缺陷,进行优势互补,是一种兼具高功率特性与较高能量密度密度特点的新型电化学储能器件,具有非常好的发展前景。隧道型氧化物Na_(0.44)MnO_2具有稳定的结构和循环性能,同时也表现出潜在的快速嵌钠反应动力学特征,原则上可作为钠离子电容器的一类低成本电极材料。从目前的研究结果来看,基于Na_(0.44)MnO_2的钠离子电容器可以实现高功率的输出,且具有较高的能量密度和长循环寿命,是一类理想的电化学储能器件。
It is urgent to explore high power and energy density,long cycle life energy storage device to meet the demand of rapid growing electric vehicles(EVs) and clean energy storage systems.Supercapacitor has high power density,good temperature characteristic and long lifespan,but with low energy density.Therefore,it is necessary to improve its energy density to broaden its application on the premise of guaranteeing power density and cycle life.Sodium-ion battery(SIBs) has expansive developing foreground in future large-scale energy storage applications due to the low cost and abundant sodium raw resource,although it has slightly lower energy density than lithium-ion battery(LIBs).In this context,we can combine the advantages of supercapacitor and sodium ion battery,the as formed sodium ion capacitor may offer good energy and power density,as well as long cycle life.In this work,tunnel structure Na_(0.44)MnO_2 is studied as the electrode for the sodium-ion capacitor,showing a promising prospect towards energy storage applications.
