Simple fabrication of Co3O4 nanoparticles on N-doped laser-induced graphene for high-performance supercapacitors

“…However, the capacitance and energy density of pure LIG is relatively low, possibly due to the limited surface of electrode material accessible to electrolyte ions. 15 Therefore, efforts have been made to modify the LIG surface by heteroatom doping (N, S, B, and P), [16][17][18] functionalization, 19 and producing hybrid composites with pseudocapacitive materials. [20][21][22] For instance, heteroatom-doped LIG electrode material exhibited signicantly improved capacitive performance compared with pristine LIG, as previously reported by our research group.…”

Status and Prospects of Laser‐Induced Graphene for Battery Applications

“…Nitrogen, sulfur, and boron-doped graphene have been synthesized by laser in a special gas, liquid, or solid environment that contains the target atoms. [60][61][62] Beyond that, when analyzed in the Raman spectrum, LIG composites exhibited a high I D /I G ratio (over 1.1), as shown in Table 1, indicating an increase in the structural distortion and doping density.…”

One-step fabrication of nitrogen-doped laser-induced graphene derived from melamine/polyimide for enhanced flexible supercapacitors

“…Moreover, the O content ratio of LIG is 5.85%, which is consistent with reports in the literature (generally > 5%). 17 Meanwhile the oxygen content in N-LIG is slightly reduced (3.15%), which may be because some of the decomposition products of melamine escape as nitrogen-oxygen compounds during the process of laser pyrolysis, and consume some O element.…”

“…24 Given the dual electrochemical behaviour of EDLC and pseudocapacitance at lower current density, the N-LIG MSC presents a C A as high as 35.20 mF cm −2 at 0.05 mA cm −2 , which is overwhelmingly larger than that of conventional unmodified s-LIG from PI (5.0 mF cm −2 at 0.05 mA cm −2 ) without the heteroatom doping. 17 Besides, the C A value of the N-LIG MSC is superior to those of previously reported MSCs of modified LIG and some LIG based on other polymers, like Fs-LIG (22.40 mF cm −2 at 0.10 mA cm −2 ), 47 air-plasma treated LIG (28.50 mF cm −2 at 0.02 mA cm −2 ), 4 KOH-activated LIAG/KC-35 (30.06 mF cm −2 at 0.05 mA cm −2 ), 48 lignin/PVA-based LIG (25.10 mF cm −2 at 0.05 mA cm −2 ), 49 and SPEEK-based LIG (1.90 mF cm −2 at 0.20 mA cm −2 ). 50 In addition, the C A value of the N-LIG MSC is higher than those of previously reported MSCs of heteroatom doped LIG and pseudocapacitive loaded LIG, such as N-d-LIG (20.80 mF cm −2 at 0.05 mA cm −2 ), 19 B-LIG (16.50 mF cm −2 at 0.05 mA cm −2 ), 7 N-doped LIG with PEDOT (0.79 mF cm −2 at 0.05 mA cm −2 ), 6 and MoS 2 -LIG (16.20 mF cm −2 at 0.10 mA cm −2 ).…”
