“…The electrode films with 3D current collectors showed excellent performances in all those aspects compared with that using flat current collectors (Figure 6a). In order to further demonstrate the potential of our 3D current collectors for practical applications, we evaluated their weight percentage ρ wt and volume percentage ρ vol in the entire electrode films [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][23][24][25]42,53] (Figure 6b; Table S2, Supporting Information), which are critical for lightweight and compact energy storage. The mass density of our 3D current collector was 5.64 mg cm -2 , no heavier than that of commonly used flat aluminum foil with thickness of 20 µm in most commercial supercapacitors.…”

“…b) Weight and volume percentages of active materials in total electrodes for our supercapacitors using 3D aluminum current collectors (red star) and the reported ones in literature. [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][23][24][25]42,53] c) Ragone plots of gravimetric and d) volumetric energy density versus power density for our supercapacitors using 3D aluminum current collectors in comparison with the state-of-the-art commercial (activated carbon) supercapacitors, [54][55][56] lithium thin-film batteries, [52] lithium-ion batteries [54] and lead-acid batteries. [54] Note that all energy density and power density values are calculated on the basis of the entire device stack.…”

“…[1][2][3][4] Supercapacitors (SCs) are considered to be one kind of promising energy storage device due to their high power density and safety, fast charge and discharge speeds, and long cycle life. [5][6][7] The electrode materials of SCs are one of the key factors in determining the electrochemical performance. Common electrode materials are mainly carbon materials, metal oxides, and conductive polymers.…”

“…The development of high‐performance energy storage devices has been accelerated to meet the fast growing sectors of portable electronics and electric vehicles [1–4] . Supercapacitors (SCs) are considered to be one kind of promising energy storage device due to their high power density and safety, fast charge and discharge speeds, and long cycle life [5–7] . The electrode materials of SCs are one of the key factors in determining the electrochemical performance.…”

“…Indeed, fabrication parameters are crucial steps that should in principle exacerbate the performance of the electrode materials. However, for some obscure reasons, only a few papers are dedicated to electrode fabrication [ 1 , 2 , 3 , 4 , 5 ], and even fewer focus on the standardization of the electrode preparation and testing [ 6 ]. Prototyping ‘real life’ cells is also seldom reported [ 7 , 8 ].…”
