MnCoP hollow nanocubes as novel electrode material for asymmetric supercapacitors

ZIF-67 Derived Co2VO4 Hollow Nanocubes for High Performance Asymmetric Supercapacitors

“…Subsequently, the internal ZIF-67 was completely consumed, and ZIF-67/CoVO was converted to CoVO-HNC. Furthermore, the hollow structure can alleviate the volume expansion during charging and discharging to prevent structural damage, thereby prolonging the service life [ 31 ]. HRTEM images ( Figure 2 f), distinct lattice stripes of CoVO-HNC can be observed with crystal plane spacing of 0.252 nm and 0.209 nm, corresponding to the (311) and (400) crystal planes, in agreement with the XRD results.…”

Hollow Structured Transition Metal Phosphates and Their Applications

“…A hollow nanosphere of amorphous iron doped manganese phosphate (Fe−Mn : P) was synthesized using a two‐step solvothermal method where amorphous manganese phosphate was produced at first which further reacts with iron nitrate at 180 °C for 2 hours to form a hollow nanosphere [78] . The hollow nanocubes of MnCoP were synthesized by hard acid soft base principles where cuprous oxide, cobalt chloride, and manganese chloride were used followed by the phosphorization to get hollow nanocubes [80] . Ni−Mn(PO 4 ) 2 composite was prepared by manganese chloride and nickel chloride under probe sonication mixing with Na 2 HPO 4 dropwise.…”

A high-performance hybrid supercapacitor by encapsulating binder-less FeCoSe2 nanosheets@NiCoSe2 nanoflowers in a graphene network

“…3,4 Supercapacitors as one of the renewable ESDs have become a research hotspot thanks to their unique features, such as super-long cyclic durability, good rate capability, high-power density, and rapid charge/discharge, and wide use in electronic equipment, power grids, and electrical vehicles. [5][6][7][8][9][10][11][12] However, their limited energy density remains a hindrance in their widespread commercial applications. 13 Hybridization of capacitive-type and battery-type electrodes offers an effective approach to enhance their energy densities.…”
