An overview of recent progress in the development of 2D manganese oxide nanosheet‐based pseudocapacitors is provided, with emphasis on underlying methods and strategies. 2D manganese oxide nanosheets are sheet‐like monocrystallites of ≈0.5 nm thickness and lateral dimensions of 50–5000 nm. MnO2 nanosheets are synthesized in the form of colloids, which can be readily utilized in wet‐chemical processes like ink‐jet printing. The synthetic strategies to make 2D δ‐MnO2 nanosheets by bottom‐up and top‐down approaches are discussed, and the relationship between the ionic defect structure of δ‐MnO2 nanosheets and their pseudocapacitance is explained. The basic principles and experimental challenges of ink‐jet printing of 2D materials at high resolution, and the development of 2D nanosheet‐based inks are discussed, with emphasis on δ‐MnO2, graphene, and graphene oxide. The fabrication and performance of δ‐MnO2 nanosheet derived pseudocapacitors, including ink‐jet printed flexible microsupercapacitors, is described. The relationship between the electrode thickness and layer architecture and the specific capacitance is explained.

MnO2-纳米片基伪电容器的喷墨印刷进展
本文概述了基于二维氧化锰纳米片的伪电容器的最新开发进展，重点是基础方法和策略。二维氧化锰纳米片是片状单晶，厚度约为0.5 nm，横向尺寸为50-5000 nm。MnO 2纳米片是以胶体的形式合成的，可以很容易地用于喷墨打印等湿化学工艺中。合成策略，使2Dδ-的MnO 2个纳米片通过自下而上和自上而下的方法进行了讨论，并且所述离子缺陷结构之间的关系δ-的MnO 2纳米片及其伪电容进行了解释。的基本原理，并在高分辨率2D材料的喷墨印刷的实验挑战，和2D基于纳米片化油墨的发展进行了讨论，重点是δ-的MnO 2，石墨烯，石墨烯和氧化。制造和δ-的MnO性能2纳米片衍生的赝，包括喷墨印刷的柔性microsupercapacitors，进行说明。解释了电极厚度和层结构与比电容之间的关系。
