Abstract Restricted rate capability is the key bottleneck for large‐scale energy storage of battery‐type supercapacitor cathode due to its sluggish reaction kinetics. Herein, Ni(Co)Se 2 @Co(Ni)Se semicoherent heterojunctions with rich Se vacancies (Vr‐Ni(Co)Se ) as are first constructed. Such a vacancy and heterointerface manipulation can not only essentially regulate electronic structure enhance ions adsorption capability, but also rationalize chemical affinities OH – in diffusion pathway...
Bismuth ferrite (BiFeO 3 ) powders were synthesized by a sol–gel process using polyvinyl alcohol (PVA) as complexing agent. Thermogravimetric, Fourier transform infrared spectroscopy, X‐ray diffraction (XRD), and field‐emission scanning electron microscope techniques used to characterize precursor derived oxide powders. The effect of the ratios positively charged valences hydroxyl groups PVA (M n + /–OH) on formation BiFeO was investigated. XRD analysis showed that single‐phase...
Developing novel hybrid negative electrode materials with high specific capacity, rate capacitance, and long-term cycle stability is a key factor for pushing large-scale application of supercapacitors. However, construction robust interfaces low-crystalline active plays crucial role in realizing the target. In this paper, one-step phosphorization approach was employed to make Fe2P2O7 nanoplates closely bonded N/P-co-doped graphene nanotubes (N/P-GNTs@b-Fe2P2O7) through interfacial chemical...
Cathodes undergo unavoidable lithium loss due to the formation of a solid electrolyte interface (SEI), which seriously affects energy density iron phosphate (LFP) batteries. To compensate for initial capacity loss, we introduced an NiCo-Li2Se nanocomposite LFP battery system act as competitive cathode prelithiation additive. Benefiting from its zero gas-emissions, ambient stability, high irreversible capacity, low delithiation potential, and good compatibility with carbonate-based...

Abstract Transition metal selenides (TMSs) have been extensively explored as the most attractive battery-type supercapacitor cathodes. However, TMSs usually exhibit elusive active sites, sluggish reaction/diffusion kinetics, and poor conductivity, which severely degrade their capacity rate performance. To overcome these shortcomings of TMSs, herein, we employ a synchronous strategy Mn donor doping Se vacancy in flower-like Ni 3 4 cathode optimize dopant/vacancy concentration (V Se(M) –Mn (M)...
Holding ultralong cycle life and superior rate capability with high specific capacity is an inevitable requirement for the practical applications of transition metal compounds battery-type supercapacitor electrode materials. In this paper, a novel class phosphide (TMP) nanostructures evenly bonded on N/P co-doped graphene nanotubes (N/P-GNTs@b-TMP) firstly built via one-step in-situ growth procedure. The N, P elements as substitutions C in GNTs skeleton introduce rich electronic centers,...
