超级电容器用石墨烯基电极材料的制备及性能研究

3.结束语

石墨烯基材料有多种微组织结构，应用于超级电容器电极材料的前景非常广阔。近几年来，关于合成石墨烯和氧化石墨的文献数量呈雪崩式增长，这些理论研究为石墨烯在储能领域的应用提供了理论基础和制备方法。当前，如何有效控制生产成本、简化生产工艺、创造环境友好的生产方式、提高石墨烯的品质和生产效率，仍需进一步完善。

为了充分发挥石墨烯作为电极材料的优异性能，制备石墨烯的过程当中，需要对其在不同的加工过程中的物理和化学性质深入了解，才能控制纳米粒子在石墨烯表面的分布、结构、形貌及数量，并保持石墨烯良好的本征性质。为了加快化学剥离法生产商品化石墨烯的工业化进程，一些关键性问题，例如石墨的彻底剥离，单层或多层石墨烯在不同溶剂中的稳定分散，保留二维石墨烯的本征特性等，仍亟待处理。

通过对石墨烯基电极材料的深入研究，人们会对这种新型二维纳米材料的本征结构和性质有更加深刻的理解和认识，而后必将产生一系列石墨烯基新型电极材料，从而为石墨烯的实际应用提供理论基础和技术支撑。
