1. 研究目的与意义（文献综述）

近年来，随着电子设备小型化、微型化的发展趋势，极大促进了人们对微型储能装置的需求。

目前，微型设备主要依赖于薄膜电池或者微型电池提供能量，虽然这两类储存器件已经成功实现商品化，但是，微型电池的循环性能较差，功率密度较低，在制造、更换与维护过程中成本过高，并伴随着一系列资源浪费与环境污染的问题。

相对与微型电池，微型超级电容器能够在极短时间内完成充放电，具有很高的功率密度，同时具有极高的循环寿命，被认为是极具潜力的微型储能器件。

2. 研究的基本内容与方案

近年来在高能量密度微型储能器件的研究中，采用高比容量电容器材料、优化电极微结构、应用离子液体电解质、非对称/混合型器件构筑等方法，可极大提升微型储能器件的能量密度。

本论文研究工作利用磷酸钛钠与硫化钴铁分别作为钠离子容器的负极和正极，在微电极的构筑过程中，使用水热法以合成磷酸钛钠与硫化钴铁，并通过调控活性物质、光刻胶和稀释液的配比，经过搅拌和超声后，获得分散均匀、粘度适中的活性物质/光刻胶复合材料，以此法制备了磷酸铁锂/光刻胶复合材料与氮化钒/光刻胶复合材料。

将复合材料于洁净的硅基板表面上匀胶，得到表面均匀光滑无颗粒的薄膜，烘干后采用紫外光刻技术制作叉指型微图案，并经对准套刻、显影和热解碳化制得基于非对称微电极的微型锂离子电容器。
