Metal/Covalent‐Organic Framework Based Cathodes for Metal‐Ion Batteries

Abstract: world's energy system from non-renewable fossil energy to low-carbon and multienergy fusion. How to fully develop and efficiently utilize clean energy to achieve carbon emission reduction has become a common concern of all countries around the world. In recent years, highly efficient electrochemical energy storage devices have attracted more attention and significantly impacted on scientific and industrial communities. [1] They can execute intermittent power storage and release, unrestricted by the geographica… Show more

“…[16] Figure After linear fitting, the values of b for two peaks are 0.72 and 0.82, respectively (Figure 3c), implying both capacitive and diffusion-controlled mechanisms are involved during the charge/ discharge process. The respective capacity contributions from the capacitive and diffusion-controlled process can be further estimated by the equation below: 3) in which k 1 v and k 2 v 1/2 are currents from capacitance and diffusion-controlled process. [16] Capacitive contributions are 57.0%, 67.1%, 73.0%, 82.2%, and 84.6% at the scanning rate of 0.1, 0.25, 0.75, 1.5, and 2 mV s −1 , respectively (Figure 3d and Figure S10, Supporting Information).…”

“…[2] Among them, Na stands out since it is the fourth most resourceabundant metal on the earth's crust; besides, it shows similar physicochemical properties as Li and low redox potential (Na/Na + : 2.73 V vs standard hydrogen electrode). [3] On the other hand, as an emerging novel type of energy storage device, dual-ion batteries (DIBs) has drawn great attentions recently attributing to its advantages of low material cost, high working voltage, and being environmentally friendly; and the fast anion intercalation kinetics at graphite cathode is also beneficial to achieve high rate performance compared with previously reported cathode materials that are based on Na + intercalation/de-intercalation. [4] Therefore, by integrating the merits of Na and DIBs, the Na-DIBs show great potential for energy storage applications in large scale.…”

“…While, the carbonaceous materials, as a conductive matrix or coating, can only increase the interparticle ion/electron transport of active materials, i.e., the external charge transfer is improved, the internal charge transfer and transport are still not enhanced by the effect of carbonaceous materials. [20,21] Thus, to enhance the internal ion/electron transport further, the design of a bimetallic selenide heterojunction with unique phase boundaries has been a promising route to accelerate the kinetics of the conversion reaction by coupling nanomaterials with different work functions. [22,23] For example, our group synthesized a heterojunction structures of Co 3 Sn 2 /SnO 2 as anode material for SIBs.…”

“…As a kind of crystalline hybrid material made up of metal ions and organic ligands, metal–organic frameworks (MOFs) can provide an ideal porous skeleton with high specific surface area, high porosity, diverse structures, and tunable flexibility. Various MOF-derived nanostructures can be obtained through facile and appropriate subsequent treatment, including porous carbons, metal-based oxides/nitrides/sulfides/selenide/phosphides, etc . , More importantly, MOF-derived nanostructured hybrid materials can make the isolated nanoactive materials more stable, thereby improving electrochemical performance. Nevertheless, the research on Sb-based MOF-derived materials in SIBs is rarely reported so far.…”
