“…This is often realized by synthesizing nanoporous carbon materials (NPCs) and controlling parameters such as pore‐size and pore‐size distribution (PSD) in the ultramicroporous, microporous and mesoporous regions, specific surface area (SSA) and pore volume, along with structure density, electrical conductivity and surface heterogeneity/redox site concentration. [ 1–28 ] Considering these factors, highly electrically conducting and flexible graphene‐related materials with facile surface chemical modification and open framework formation can generate surface‐accessible porous structures with heterogeneity/functionality. Thus far, numerous design and synthesis routes have been proposed to produce viable functional graphene nanostructures and impressive capacitance performance has been achieved compared to the typical highly porous NPCs (refer to Tables S1 and S2, Supporting Information).…”

Supercapacitors formed from porous carbon and graphene‐oxide (GO) materials are usually dominated by either electric double‐layer capacitance, pseudo‐capacitance, or both. Due to these combined features, reduced GO materials have been shown to offer superior capacitance over typical nanoporous carbon materials; however, there is a significant variation in reported values, ranging between 25 and 350 F g−1. This undermines the structure (e.g., oxygen functionality and/or surface area)‐performance relationships for optimization of cost and scalable factors. This work demonstrates important structure‐controlled charge storage relationships. For this, a series of exfoliated graphene (EG) derivatives are produced via thermal‐shock exfoliation of GO precursors and following controlled graphitization of EG (GEG) generates materials with varied amounts of porosity, redox‐active oxygen groups and graphitic components. Experimental results show significantly varied capacitance values between 30 and 250 F g−1 at 1.0 A g−1 in GEG structures; this suggests that for a given specific surface area the redox‐active and hydrophilic oxygen content can boost the capacitance to 250–300% higher compared to typical mesoporous carbon materials. GEGs with identical oxygen functionality show a surface area governed capacitance. This allows to establish direct structure‐performance relationships between 1) redox‐active oxygen functional concentration and capacitance and 2) surface area and capacitance.

New manufacturing strategies toward customizable energy storage devices (ESDs) are urgently required to allow structural designability for space and weight-sensitive electronics. Besides the macroscopic geometry customization, the ability to fine-tune the ESD internal architectures are key to device optimization, allowing short and uniform electrons/ions diffusion pathways and increased contact areas while overcoming the issues of long transport distance and high interfacial resistance in conventional devices with planar thick electrodes. ESDs with 2D or 3D electrodes filled with liquid or gel-like electrolyte have been reported, yet they face significant challenges in design flexibility for 3D ESD architectures. Herein, a novel method of assembling ESDs with the ability to customizing both external and internal architectures via digital light processing (DLP) technique and a facile sequential dip-coating process is demonstrated. Using supercapacitors as prototype device, the 3D printing of ESDs with areal capacity of 282.7 mF cm −2 which is higher than a reference device with same mass loading employing planar stacked configuration (205.5 mF cm −2 ) is demonstrated. The printed devices with highly customizable external geometry conveniently allow the ESDs to serve as structural components for various electronics such as watchband and biomimetic electronics which are difficult to be manufactured with previously reported strategies.
