Improved electrochemical performances of core-shell Cu2O/Cu composite prepared by a simple one-step method

High specific capacity retention of graphene/silicon nanosized sandwich structure fabricated by continuous electron beam evaporation as anode for lithium-ion batteries

“…Developing high-performance rechargeable lithium-ion batteries (LIBs) with high energy, power density, and long lifespan for commercial applications, such as portable electronic devices and electric vehicles, has attracted much interest [1][2][3][4][5][6][7]. High-capacity LIBs are in-demand.…”

Pulsed laser deposited Cr2O3 nanostructured thin film on graphene as anode material for lithium-ion batteries

“…However, the fact that their performance, in terms of energy and power density requires continuous improvement has encouraged ever-greater scientific efforts toward the search for new materials that could replace the current state-of-the-art materials [3]. A large number of transition metal oxides, such as Fe 2 O 3 [4], Nb 2 O 5 [5], Ta 2 O 5 [6], ZnO [7], MnO [8], NiO [9], Co 3 O 4 [10], Cu 2 O [11], have been investigated as promising anode materials for lithium-ion batteries [12]. In 2000, Poizot et al [13] reported that nanosized transition metal oxides react reversibly with lithium at room temperature.…”

A new high-performance cathode material for rechargeable lithium-ion batteries: Polypyrrole/vanadium oxide nanotubes

“…These results indicate that PPy/VOx-NTs have higher capacity and faster kinetics than those of VOx-NTs [8,19]. The improved electrochemical properties for PPy/VOx-NTs may be not only attributed to the flexible charac- teristic of the polypyrrole, which can buffer the volume change during cycling, but also to the high electronic conductivity of the polypyrrole, which can provide more pathways for charge transfer [7,20].…”
