Description

technical field [0001] The invention relates to the technical field of energy storage ceramic materials, in particular to a tin-doped lead lanthanum zirconate titanate thick-film ceramic and its preparation and application. Background technique [0002] In recent years, dielectric capacitors have been increasingly used in radars, lasers, and pacemakers due to their high power density, fast charge / discharge (<1 μs), low cost, and high thermal stability. However, compared with fuel cells, lithium-ion batteries, and supercapacitors, the energy storage density of dielectric capacitors is relatively low, and power electronics and pulse power systems using dielectric capacitors usually have a large volume and weight to meet their requirements. energy storage required. In order to reduce the volume and quality of such equipment and systems, and solve the limitation of the working environment temperature of some capacitors, so as to achieve the purpose of using capacitors in var...
