“…Moreover, the 3D rGO‐200//Zn exhibits a capacitance retention of nearly 90% with a coulombic efficiency above 98% at 1.5 mA cm −2 after 450 cycles (Figure 6d) without any collapse in 3D structure (Figure S18, Supporting Information). As shown in Figure 6e, the 3D rGO‐200//Zn exhibits excellent areal energy density of 266 μWh cm −2 at 0.2 mA cm −2 , surpassing the recently reported zinc ion hybrid devices, such as AC//Zn (115 μWh cm −2 ), [ 54 ] Ni@Ni(OH) 2 //Zn (110 μWh cm −2 ), [ 55 ] MXene//Zn (20 μWh cm −2 ), [ 56 ] MWCNTs‐VO 2 //MXene‐TiS 2 (35 μWh cm −2 ), [ 57 ] V 2 O 5 //MXene (49.6 μWh cm −2 ), [ 58 ] and VO 2 //Zn (188 μWh cm −2 ). [ 59 ] Such excellent performances were ascribed to the unique 3D framework with porous structure, which makes full use of the active materials and improves ion transport (Figure 6f).…”

Recently, developing matchable cathode materials of Zn ion hybrid capacitor still remains difficult owing to insufficient understanding of the charge storage behavior. However, most previous efforts are devoted to explain the effect of oxygen-containing groups without paying attention to graphitic structure. Herein, the charge storage capability and electrochemical kinetics of reduce graphene oxide (rGO) nanosheets are optimized as a function of their surface properties. Beyond the contribution of oxygen-containing groups, an extra contribution from the reversible adsorption/desorption of H + on carbon atom of rGO sheets is confirmed. Electrochemical analysis and density functional theory calculations reveal that H + induces disruption of π cloud in aromatic domain, accompanied by C sp 2 -sp 3 re-hybridization and the distortion/restoration of graphitic structure. The optimal electrochemical performance with a specific capacitance of 245 F g -1 at 0.5 A g -1 with 53% retention at 20 A g -1 is achieved for rGO thermally treated at 200 °C. As a proof-of-concept application, the 3D printed rGO electrode delivers a high areal capacitance of 1011 mF cm -2 and an energy density of 266 μWh cm -2 . The study is believed to broaden the horizons of proton adsorption chemistry and shed light on the design of novel electrode materials.

A Flexible Aqueous Zinc–Iodine Microbattery with Unprecedented Energy Density

et al. 2022

View full text Add to dashboard Cite

Currently, reported aqueous microbatteries (MBs) only show unsatisfactory electrochemical performance (≤120 mWh cm−3 volumetric energy density and <1000 μWh cm−2 areal energy density) and it remains challenging to develop durable aqueous MBs that can simultaneously offer both high volumetric and areal energy density. Herein, an in situ electrodeposition strategy is adopted to construct a flexible aqueous zinc–iodine MB (ZIDMB). Notably, the fabrication process well avoids the use of common additives (such as binders, conductive agents, and toxic solvent) and also bypasses subsequent time‐consuming procedures such as grinding, coating, drying, etc., thus greatly simplifying the manufacture of the ZIDMB. Meanwhile, owing to the suppression of the shuttle effect of triiodide ions and the high ionic conductivity of the polyelectrolyte, the ZIDMB can simultaneously deliver record‐high volumetric and areal energy densities of 1647.3 mWh cm−3 and 2339.1 μWh cm−2, thus achieving values at least 13.5‐ and 2.3‐fold better than those of best available aqueous MBs, respectively. This work affords an innovative strategy to construct an ideal micro‐power‐source for future miniaturized and integrated electronics.

Zn metal is a promising anode material for high‐energy‐density aqueous batteries, but it is plagued by dendrite, low stripping/plating efficiency, and inevitable depletion of active Zn. Herein, a low‐intercalation‐potential material, Cu7Te4, is reported as both an anode material and Zn dendrite inhibitor for aqueous Zn batteries. A low plateau of 0.2 V (vs Zn2+/Zn), high capacity of 216 mA h g–1, and superior cyclability over 4200 cycles can be realized by Cu7Te4 anode. Moreover, when Zn is modified with Cu7Te4 layer, a hybrid anode based on “intercalation–deposition” mechanism can be ingeniously developed, in which Zn2+ ions are sequentially inserted into Cu7Te4 and uniformly deposed on Zn at successive low potential. A battery built on such a mechanism sustains more than 1000 h and 1000 times in comparison to less than 100 h and 350 times of a bare Zn. Furthermore, an aqueous “rocking–chair” Cu7Te4//ZnI2 Zn‐ion full battery is further demonstrated, which can realize energy densities of 65.3 Wh kg–1 and 86% capacity retentions after 10 000 cycles. This research contributes to a stable anode material for aqueous Zn batteries and provides an effective strategy to address the Zn dendrite.
