On June 16, the British journal "Natural Materials" published the latest academic achievement "Textured Multilayer Ceramic Capacitors for Energy Storage" by Professor Xu Zhuo and Professor Li Fei from the Department of Telecommunications of Xi'an Jiaotong University online. This achievement can greatly reduce the electrical induced strain of ceramics under strong fields, and increase the energy storage density obtained by the breakdown electric field is the highest value of the known ceramic capacitors.

It turned out that ceramic capacitors, as an important energy storage electronic component, have the advantages of high discharge power, good temperature stability and long cycle life. They play a vital role in advanced electronic and power systems, especially in pulse power There are irreplaceable applications in the technical field. At present, electronic devices are developing in the direction of miniaturization and lightening, which also puts forward higher requirements on the energy storage density of ceramic capacitors. This achievement can be widely used in the field of electronic functional ceramics such as solid-state cooling ceramics based on the electric card effect to improve its stability and reliability under strong field conditions.

It is reported that in recent years, based on the anisotropic characteristics of the electrostrictive effect of perovskite crystals, the scientific research team of the Department of Telecommunications of Xi’an Jiaotong University has specifically proposed “to reduce the strain and stress of ceramic capacitors under strong fields by controlling the grain orientation , To avoid ceramic breakdown caused by micro-cracks and tensile stress, to improve its breakdown electric field strength and energy storage density" design ideas, through technical research in the past two years, greatly reduced the ceramic induced strain in the strong field The energy storage density obtained by increasing the breakdown electric field is the highest value of the known ceramic capacitors.
