As highly efficient electrochemical energy storage devices are in indispensable demand for numerous modern-day technologies, herein sluggish precipitation followed by an anion exchange procedure has been developed to synthesize an oxide-selenide mixed phase (Mn3O4/NiSe2–MnSe2) novel electrode material with high surface area and porosity for high-performance all-solid-state hybrid pseudocapacitors (ASSHPC). Mn3O4/NiSe2–MnSe2 shows a rich Tyndall effect (in H2O) and possesses randomly arranged low-dimensional crystallites of nearly similar size and uniform shape. The electrochemical analyses of Mn3O4/NiSe2–MnSe2 corroborate good electrochemical reversibility during charge transfer, superior pseudocapacitive charge-storage efficiency, and very low charge transfer and series resistance, ion-diffusion resistance, and relaxation time, which endorse the quick pseudocapacitive response of the material. The Mn3O4/NiSe2–MnSe2||N-rGO ASSHPC device demonstrates excellent charge-storage physiognomies suggestive of rich electrochemical and electromicrostructural compatibility between the electrode materials in the fabricated assembly. The Mn3O4/NiSe2–MnSe2||N-rGO ASSHPC device delivers high mass and area specific capacitance/capacity, very low charge-transfer resistance (∼0.74 Ω), total series resistance (∼0.76 Ω), diffusion resistance, and a relaxation time constant, which endorse the quick pseudocapacitive response of the device. The device delivers higher energy and power density (∼34 W h kg–1 at ∼2994 W kg–1), rate efficiency (∼17 W h kg–1 at ∼11,995 W kg–1), and cyclic performance (∼97.2% specific capacity/capacitance retention after 9500 continuous GCD cycles). The superior Ragone and cyclic efficiencies of the ASSHPC device are ascribed to the multiple redox-active Ni and Mn ions which lead to the supplemented number of redox reactions; “electroactive-ion buffering pool”-like physiognomics of Mn3O4/NiSe2–MnSe2, which facilitate the electrolyte ion dissemination to the electroactive sites even at high rate redox condition; and ideal electro-microstructural compatibility between the electrode materials, which leads to assisted charge transfer and absolute ion dissemination during the charge-storage process.

“…So far, different TMSes such as NiSe 2 , CoSe 2 , Co 0.85 Se, CdSe, MoSe 2 , and MnSe have been investigated for SC applications. Manganese selenide (MnSe or MnSe 2 ) is a p-type semiconducting material with unique magnetic and optomagnetic properties, as well as high electrical conductivity and low band gap energy (i.e., E g = ∼2.0 eV) as compared to MnO ( E g = ∼3.2 eV) and MnS ( E g = ∼4.2 eV). − Compared to other TMSes, manganese selenide has not been studied much for energy storage. Lately, Miao et al have prepared MnSe nanosheets by a hydrothermal method which delivered a discharge capacity of 88.3 mAh/g at 1/g .…”

Recently, metal selenides have gathered considerable attention for use as electrode materials for supercapacitor applications because of their substantial theoretical capacities. However, sluggish ion transport and chemical or mechanical degradation of electrode materials during continuous operation severely hamper their electrochemical performance. Herein, we have assembled MnSe (∼10−12 nm) into a 3D Ti 3 C 2 T x /rGO aerogel scaffold with bimodal pore size distribution through a low temperature hydrothermal method, followed by freeze-drying. A 3D percolation network of as-prepared MnSe/Ti 3 C 2 T x /rGO aerogel (MnSe/TCGA) improved electrolyte penetration by providing multidimensional ion transmission channels. High intrinsic conductivity of Ti 3 C 2 T x in combination with rGO facilitated electronic transport during electrochemical activity. Cellular sieves of the MnSe/ TCGA aerogel scaffold effectively interlocked MnSe particles and thereby prevented pulverization and aggregation of active material. Consequently, a MnSe/TCGA electrode with a specific architecture exhibited a significant specific capacity of 225.4 mAh/g at 1 A/g and maximum initial Coulombic efficiency of 99.5%, which surpassed the values obtained for its counterparts (i.e., MnSe/GA and MnSe). Furthermore, MnSe/TCGA showed an excellent rate capability (158 mAh/g at 12 A/g) and a superb life span (92.1% over 5000 cycles). When examined through impedance studies, MnSe/TCGA revealed low series and charge transfer resistances (R s = 2.6 Ω and R CT = 5.2 Ω). Overall, as-obtained findings provide insight on constructing high performance 3D porous and hybrid microstructures to optimize electrochemical energy storage performance.

“…The band gap energy ( E g ) of MnSe is reported to be approximately 2.0 eV, significantly lower than those of oxides (typically around 4.2 eV) and sulfides (around 3.0 eV). The reduced band gap energy in MnSe allows for electronic conduction, facilitating the movement of electrons and enhancing the overall electrical conductivity of the material. , MnSe is an efficient material for electrocatalysis process due to its plentiful defects or exposed edge sites aroused by the increased number of active sites, which are in favor of HER and water splitting . Furthermore, if one compares the oxides of Mn, the electronegativity difference between Mn and oxygen is high.…”
