Electrospun Nd3+‐Doped LiMn2O4 Nanofibers as High‐Performance Cathode Material for Li‐Ion Capacitors

“…constructed aqueous hybrid supercapacitor using electrospun LiNi 0.5 Mn 1.5 O 4 as the cathode and nitrogen‐doped graphene (NDG) as anode which delivered 72 F g −1 specific capacitance at a current density of 0.5 mA cm −2 and its energy and power densities are 15 Wh kg −1 and 110 W kg −1 , respectively . Our group also reported the electrospun LiNi 0.4 Co 0.6 O 2 nanofibers as the electrode materials for asymmetric supercapacitor in an organic medium 1 M LiPF 6 in ethylene carbonate/di‐methyl carbonate (LiPF 6 −EC:DMC) (1 : 1 v/v) and its achieved specific capacitance is 72.9 F g −1 …”

“…[24] Our group also reported the electrospun LiNi 0.4 Co 0.6 O 2 nanofibers as the electrode materials for asymmetric supercapacitor in an organic medium 1 M LiPF 6 in ethylene carbonate/di-methyl carbonate (LiPF 6 ÀEC:DMC) (1 : 1 v/v) and its achieved specific capacitance is 72.9 F g À1 . [25] In the present work, we prepared 1D nanostructured LNdMO NFs by electrospinning technique. The main aim of this study is to introduce lithium based electrode materials for Liion capacitor and nanofibrous morphology to provides a high aspect ratio, provide a shorter diffusion pathway for Li-ion insertion/extraction and facile strain relaxation upon electrochemical cyclingand also to achieves better energy density without the compromising the power density.…”

Preparation of electrospun Co3O4 nanofibers as electrode material for high performance asymmetric supercapacitors

“…This slurry is pasted on 1 cm 2 stainless steel sheet and vacuum dried at 80 C for 2 h [26]. The electrochemical measurements are performed in a three electrode configuration comprising an electrospun Co 3 O 4 nanofibers electrode, a platinum electrode and a saturated calomel electrode (SCE) that serve as the working, counter and reference electrodes, respectively using an electrochemical analyzer (VSP, Bio-Logic, France).…”

A Facile Chemical Precipitation Method for the Synthesis of Nd(OH)3 and La(OH)3 Nanopowders and their Supercapacitor Performances

“…For both the rare‐earth hydroxides based electrodes, the cyclic voltammograms are non‐symmetric, which implies an irreversible nature of the redox process. The C sp of Nd(OH) 3 and La(OH) 3 electrodes are calculated from the CV curves using the following equation, as reported previously . The calculated C sp of La(OH) 3 and Nd(OH) 3 electrodes are 321 F g −1 and 511 F g −1 at 5 mVs −1 , respectively.…”
