Tuning the Electrochemical Performance of Multiple Phased Selenides@C/MXene Composites via Controllable Synthesis of Multivariate Metal‐Organic Frameworks

“…While the peak at 0.74 V corresponds to the formation of Co/Na 2 Se [57,58] . During the charging process, only one obvious oxidation peak appears at 1.83 V, indicating the removal of Na + from the electrode [59,60] . The electrochemical behavior of NCMS@C/MX‐121 electrode mimics CoSe 2 kind materials a lot due to the higher content of CoSe 2 .…”

“…[57,58] During the charging process, only one obvious oxidation peak appears at 1.83 V, indicating the removal of Na + from the electrode. [59,60] The electrochemical behavior of NCMS@C/MX-121 electrode mimics CoSe 2 kind materials a lot due to the higher content of CoSe 2 . The CV curves of second to fourth cycles basically overlapped, proving good electrochemical reversibility of NCMS@C/MX-121 electrode.…”

Construction of a core–double-shell structured Si@graphene@Al2O3 composite for a high-performance lithium-ion battery anode

“…Electrochemical energy storage is one of the most used energystorage/conversion systems available today. 1,2 Recently, lithiumion batteries (LIBs) have occupied a large proportion of the energy-storage market and have been extensively used in electric vehicles and various portable electronic devices, such as phones, laptops and digital cameras, due to their high energy density, operating voltage, safety and long lifetime. 3,4 Recently, the boom of LIBs in electricity-driven devices in turn has led to a higher requirement on the energy density of LIBs.…”

“…11,12 To overcome the drawbacks of the Si material, several strategies have been proposed to buffer the vast volume expansion of Si. The proposed strategies include (1) decreasing the size of the Si material or lowering the dimensions of the Si material to alleviate the produced mechanical stress during the lithiation process; 8,[13][14][15] (2) developing diverse coatings to consolidate the microstructure of Si species and avoiding the continuous deposition of a solid electrolyte interphase (SEI) layer on the Si surface during the lithiation process; [16][17][18][19][20][21] (3) adding chemical additives in electrolyte to stabilize the SEI layer; [22][23][24][25] and (4) compositing the Si with highly conductive materials.
