稀土掺杂Co3O4基超级电容器研究进展

Research Progress on Rare Earth Doped Co 3O 4 in Supercapacitors

由于Co 3O 4具有易于制备、环境友好、成本低廉并且具有相对较高的比电容等优点,被认为是一种很有潜力的超级电容器材料,但是由于Co 3O 4电极材料导电性差,所以导致其电化学性质受到一定的限制。然而,稀土是一组具有独特性质的元素,发现稀土元素在先进储能领域的应用,是将稀土化学与储能技术联系起来的重要契机。因此本文综述了稀土掺杂四氧化三钴在超级电容器的研究进展,讨论了稀土元素在超级电容器的研究现状。

Because Co 3O 4 has the advantages of easy preparation,environmental friendliness,low cost,and relatively high specific capacitance,it is considered to be a potential supercapacitor material,but due to the poor conductivity of Co 3O 4 electrode material,its electrochemical properties are affected by certain restrictions.However,rare earths are a group of elements with unique properties.It is found that the application of rare earth elements in the field of advanced energy storage is an important opportunity to connect rare earth chemistry with energy storage technology.Therefore,the research progress on rare earth doped cobalt tetroxide in supercapacitors was summarized,and the research status of rare earth elements in supercapacitors was discussed.
