改性对钛酸钡基陶瓷储能密度的影响

摘要

For the important application of BaTiO3 based ceramics in energy storage,the physical basis and influencing factors of energy storage in dielectrics were introduced.On this basis,the effects of modification methods such as doping with equivalent ions and different ions as well as coating on dielectric properties and energy storage density of BaTiO3 based ceramics were discussed.Meanwhile,it's concluded that optimizing the combination of doping modification and coating modification is an important way to improve the energy storage density of BaTiO3 based ceramics.%基于钛酸钡(BaTiO3)基陶瓷在储能方面的重要应用,介绍了电介质储能的物理基础和影响因素.在此基础上,主要讨论了等价离子掺杂改性、异价离子掺杂改性和包覆改性等对钛酸钡基陶瓷介电性能和储能密度的影响.同时指出优化掺杂改性和包覆改性的组合是提升钛酸钡基陶瓷储能密度的重要途径.
