微型器件系统迅速发展的同时要求电源系统的微型化，薄膜化以及全固态化。在柔性储能器件的应用中，薄膜电极材料的微结构调控是高性能膜设计的关键。锰基氧化物由于可以通过生长工艺调控其结构、形貌以及尺寸等，为实现其膜微结构的调控提供了多样性。项目利用Langmuir-Blodgett技术构筑锰基氧化物薄膜表面微结构，以薄膜的微结构调控和优化为出发点，围绕膜微结构的形成机理及控制方法，电容性能与膜微结构的关系两个关键科学问题，揭示膜微结构的调控和电容性能之间的构效规律，旨在能够通过利用简单的方法构筑高电压、高倍率性能和高能密度比的薄膜电极材料。

The rapid development of micro-device system requires the miniaturization, thin film as well as all solid state for the power system. In the application of flexible energy storage devices, controllable microstructure for thin film electrode materials is the key point to the design for high performance films. The structure, morphology and size of manganese-based oxides can be controlled via the growth process, which provides the diversity of microstructure. The optimization for the microstructure of thin films is a useful starting point for the project. There are two key scientific problems which are the microstructure formation mechanism and control method of the films and the relationship between the capacitance performance and microstructure. Our aims were to build electrode materials using surface patterning based on Langmuir-Blodgett technique with high voltage and high rate performance for lithium ion batteries and high energy density for all solid-state flexible supercapacitors.
