Development of electroceramics for next generation high capacitance multi-layer ceramic capacitors

该项目旨在建立组成-微观结构-结构-性能关系，以帮助开发用于电动汽车应用的下一代MLCC。利用BaTiO 3缺陷化学的知识，我们将能够设计新的/改性的BaTiO 3基配方，并使用我们新的狭缝模头设备（亨利罗伊斯研究所）对这些材料进行厚膜处理，以创建基于现有架构（基于核-壳复合颗粒的单层）和/或我们小组最近提出的新架构（例如，双层纳米晶）的原型器件。材料和原型将在谢菲尔德和AVX进行表征和测试（如适用）。AVX还将使用其生产设施建造有前途的材料/架构的MLCC。

The project aims to established the composition-microstructure-architecture-property relationships to help in developing the next generation MLCCs for electric vehicle applications. Using knowledge of the defect chemistry of BaTiO3 we will be able to design new/modified BaTiO3-based formulations and process thick film dielectrics of these materials using our new slot-die facilities (Henry Royce Institute) to create proto-type devices based on existing architectures (single layers based on core-shell composite grains) and/or novel architectures (eg, bilayers of dielectrics) as recently proposed by our group. The materials and proto-types will be characterised and tested in both Sheffield and AVX, as appropriate. AVX will also build MLCCs of promising materials/architectures using their production facilities.
