Prussian-blue type FeFe(CN)6 nanocrystals with perfect nanocubic morphology were prepared by a facile hydrolytic precipitation method using Fe(CN)[Formula: see text] as a single iron-source. The resulting FeFe(CN)6 nanocrystals have subsequently been encapsulated within a mixed electronically and ionically conducting polystyrene sulfonic acid (PSS)-doped poly(3,4-ethylenedioxythiophene) (PEDOT) (PEDOT-PSS) with ethylene glycol (EG) as the polar solvent to obtain a high electrical conducting organic–inorganic nanohybrid. The FeFe(CN)6/PEDOT-PSS nanohybrid offers discharge capacity of [Formula: see text], which is improved compared to that of the naked FeFe(CN)[Formula: see text]. Also, it demonstrated the improved capacity retention and rate capability, which makes it a promising way for high performance Li-ion batteries for energy storage application.

Lithium and Mn rich solid solution materials Li [ Li 0.26 Ni 0.07 Co 0.07 Mn 0.56] O 2 were synthesized by a carbonate co-precipitation method and modified with a layer of graphene. The graphene-modified cathodes exhibit improved rate capability and cycling performance as compared to the bare cathodes. Electrochemical impedance spectroscopy (EIS) analyses reveal that the improved electrochemical performances are due to acceleration kinetics of lithium-ion diffusion and the charge transfer reaction of the graphene-modified cathodes.

The potential use of multi-walled carbon nanotubes (MWCNTs) produced by chemical vapour deposition (CVD) as a conductive agent for electrodes in Li-ion batteries has been investigated. LiNi0.33Co0.33Mn0.33O2 (NCM) has been chosen as active material for positive electrodes, and a nano-sized TiO2-rutile for the negative electrodes. The electrochemical performances of the electrodes were studied by galvanostatic techniques and especially the influence of the nanotubes on the rate capability and cycling stability has been evaluated. The addition of MWCNTs significantly enhanced the rate performances of both positive and negative electrodes and improved the capacity retention upon cycling. The obtained results demonstrated that the addition of MWCNTs in low amounts to the electrode composition enables an increase in both energy and power density of a Li-ion battery.

Willow catkins as a kind of seasonal biomass are harmful to human health in terms of causing respiratory ailments and skin anaphylaxis every spring. To explore the high-value utilization of willow catkins, in this study, we attempt to develop a kind of tin-based anode materials with willow catkin derived carbon (WCC) as the matrix. A designed solvent-thermal method involving thiourea as stabilizer and acetone–H2O mixture as solvent has been employed to fabricate SnO2–WCC composites, which exhibit uniform deposition of well-dispersed SnO2 nanoparticles on the surface of WCC. As an anode material for lithium-ion batteries (LIBs), the SnO2–WCC composite delivered a stable discharge capacity of 565[Formula: see text]mAh g[Formula: see text] at 100[Formula: see text]mA g[Formula: see text] after 70 cycles and a good rate capability of 349[Formula: see text]mAh g[Formula: see text] at 1000[Formula: see text]mA g[Formula: see text]. The high dispersity of SnO2 nanoparticles and high conductivity of WCC are both believed to contribute to the excellent electrochemical performances. These results suggest the potential of willow catkins derived carbonaceous materials applied in anode materials of LIBs and shed light on the creation of advanced carbon materials from other biomass materials towards energy storage applications.
