摘要
超级电容器具有功率密度高、充放电速度快、使用寿命长等优点,被认为是最有前途的储能装置之一。电极材料是影响超级电容器性能的决定性因素,其中,钛基材料以其天然丰度、低毒、低成本和易制备等优点被作为超级电容器的候选电极材料,并得到广泛研究。研究人员通过对其形貌结构的调控,从而达到提高电极材料电化学性能的目的,使其在众多能源功能材料中更具竞争力。文中介绍了超级电容器的储能机理及几种常见钛基材料的应用与改性,展望了钛基材料在超级电容器中的应用前景。
Supercapacitors are considered to be one of the most promising energy storage devices because of their high power density,fast charging and discharging speed,and long service life.The electrode material is a crucial factor affecting the performance of supercapacitors.Titanium-based materials have been widely studied as candidate electrode materials for supercapacitors due to their natural abundance,low toxicity,low cost,and easy preparation.In order to improve the electrochemical performance of electrode materials,researchers manipulate their morphology and structure to make them more competitive among many energy functional materials.This article introduces the energy storage mechanism of supercapacitors and the application and modification of several common titanium-based materials and looks at the favorable prospects of titanium-based materials in supercapacitors.
