One‐Pot Synthesis of CuCo2S4 Sub‐Microspheres for High‐Performance Lithium‐/Sodium‐Ion Batteries

“…[12] Yu's group employed a facile in-situ template removal process to receive NiCo 2 S 4 @C hollow nanospheres consisted of ultrathin nanosheets, which achieved a high capacity of 1137 mA h g À 1 for LIBs. [14][15][16][17][18][19][20] Additionally, the merits of high specific capacity, excellent electronic conductivity, rich redox action sites also endowed CuCo 2 S 4 with a promising prospective in application of energy-storage batteries.

“…For instance, Zhao and his collaborators synthesized CuCo 2 S 4 /reduced graphene oxide nanocomposites as SIBs anode materials with a reversible specific capacity of 433 mA h g À 1 at 100 mA g À 1 after 50 cycles. [18,22] Moreover, to our knowledge, there is seldom reports of CuCo 2 S 4 as SIBs anode materials. [21] Sun's group prepared CuCo 2 S 4 hollow sphere @N/S doped graphene composites as high performance anode materials for LIBs by two-step synthesis.…”

Recent Progress in Two‐Dimensional Layered Double Hydroxides and Their Derivatives for Supercapacitors

“…In the CuCo 2 S 4 @NiMn LDH core-shell hybrid arrays, conductive CuCo 2 S 4 serves as the core and LDH as the active shell. The composite demonstrateda nu ltrahighs pecific capacitance of 2520 Fg À1 at 2Ag À1 ,g ood rate capability,a nd excellent cycling stability, [149] and was superior to those of the individual CuCo 2 S 4 NRAs and LDH. [76] Ni 3 S 2 and Co 9 S 8 have also been selected for combination with LDH to form composite-typee lectrode materials, examples of which are Ni 3 S 2 @rGO@NiAl LDHs nanoarrays [15] and NiCo LDH/Co 9 S 8 [150] .Y ilmaz et al employed ZIF-67 (a type of MOF) as the sacrificial template to synthesize NiCo LDH and NiCo LDH/Co 9 S 8 composites.…”

A Facile Grinding Method for the Synthesis of 3D Ag Metal–Organic Frameworks (MOFs) Containing Ag6Mo7O24 for High‐Performance Supercapacitors

“…[7,8,9] The electrode materials are the main factor affecting the performance of SCs. In particular, pseudo-capacitor electrode materials can fall into three types:c arbon, [10] conductive polymers, [11][12][13] and metal oxides, [14,15] hydroxide, sulfides, [16] and their composites. [17,18] However,o wing to the redoxr eaction, these materials can undergo mechanical changes,s ot hey usu-ally show poor mechanical stability and then the electrode is not ablet oe xpand or shrink.…”
