Recent advances and perspectives of 3D printed micro-supercapacitors: from design to smart integrated devices

Abstract

3D-printed micro-supercapacitors (MSCs) have emerged as the ideal candidates for energy storage devices owing to unique characteristics of miniaturization, structural diversity, and integration. Exploring the 3D printing technology for various...

DLP printing of a flexible micropattern Si/PEDOT:PSS/PEG electrode for lithium-ion batteries

“…, involving the use of toxic precursors, attaining appropriate rheological properties, preparing highly viscous inks, requiring suitable material density and lack of self-standing ability. 13…”

“…12 Inkjet and extrusion printing-based fabrication require complex preparatory stages and restrictions on the printing resolution, which are not scalable to large-scale manufacturing processes, e.g., involving the use of toxic precursors, attaining appropriate rheological properties, preparing highly viscous inks, requiring suitable material density and lack of self-standing ability. 13 Another strategy involves applying UV-curable gel electrode inks to fabricate devices, but the parameters of gel inks still need to be adjusted and the inks need to be cured after printing. 14 Another problem is the difficulty of transmitting ions and electrons as the thickness of the electrode increases.…”

A focus review on 3D printing of wearable energy storage devices

“…[12][13][14][15] In comparison, the cost-effective customized production of WESDs is still facing huge challenges. [16][17][18] To meet the more stringent practical requirements for WESDs such as light weight and mechanical robustness, there is a need to adopt a more suitable fabrication technology. [19][20][21] In addition, WESDs should offer adequate energy storage capacity to support a wide range of wearable electronics.…”

“…It can also greatly facilitate device minimization, component assembly and integration of electrochemical energy storage devices. [16][17][18] Therefore, 3D printing enables scalable, precise fabrications of WESDs embedded in a wearable device. 16,[27][28][29] WESDs, as the name implies, should be worn comfortably on human bodies without causing any hindrance to human motion and daily activities.…”
