Designing of 3D LSG/CoNi2S4 nanosheets micro-electrodes for flexible highenergyintegrated micro-supercapacitors

Over the past years, self-powered micro-systems such as wireless sensor networks, wearable and biomedical implants, micro-robots, active tags and remote sensors have been developed dramatically [1-2]. Accordingly, extensive efforts have been devoted to design of in plane energystorage systems with high energy and power, small volume, light weight and low cost that can integrated on flexible chips [3-4]. Presently, although commercially thin-film micro-batteries are the major power sources for these devices but micro-supercapacitors (MSCs) are the most promising candidates because of their higher power density, much longer operating lifetime,excellent safety and better rate capability [5-6].In order to introduce high performance MSCs, various kinds of carbon have been utilized. But,owning to EDLC mechanism, carbon based MSCs have a low energy density. In addition,conventional lithographic techniques are not cost-effective [7-8]. Thus, a facile and low cost preparation process resulting flexible high energy MSC devices is still challenging.
