Special Issue Information

Dear Colleagues,

With the ever-growing applications of the lithium-ion battery (LIB), from consumer electronics to electric vehicles, the demand for Li-ion batteries with increased energy density is more urgent than ever before. High energy density LIBs need both anode and cathode materials with high capacities for hosting Li-ions. In response to this demand, considerable research efforts have been directed toward improving the energy density of batteries by developing high-capacity electrode materials such as Li-rich (or Li-excess) cathodes, Ni-rich cathodes, and Si anodes, and other high-capacity anode and cathode materials. High-capacity anode research, in particular, has been active, and materials such as silicon (Si), tin (Sn), germanium (Ge) and tin oxides (SnOx) have received significant attention. To address the most state-of-the-art in the research and development of high capacity electrodes (both anode and cathode) for lithium-ion batteries, in this Special Issue, we invite research, review articles, and perspectives. The contents of the manuscripts will include, but are not limited to, the following topics:

  • High capacity cathode materials for lithium-ion batteries
  • High capacity anode materials for lithium-ion batteries
  • Alloying anode (e.g., Si. Sn, Ge, etc.)
  • New design and concept for high capacity electrodes
  • Methods for performance analysis and material characterization
  • Various cell design with different combination of anode and cathode.

Centrifugally Spun α-Fe2O3/TiO2/Carbon Composite Fibers as Anode Materials for Lithium-Ion Batteries

We report results on the electrochemical performance of flexible and binder-free α-Fe2O3/TiO2/carbon composite fiber anodes for lithium-ion batteries (LIBs). The composite fibers were produced via centrifugal spinning and subsequent thermal processing. The fibers were prepared from a precursor solution containing PVP/iron (III) acetylacetonate/titanium (IV) butoxide/ethanol/acetic acid followed by oxidation at 200 °C in air and then carbonization at 550 °C under flowing argon. The morphology and structure of the composite fibers were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), and thermogravimetric analysis (TGA). These ternary composite fiber anodes showed an improved electrochemical performance compared to the pristine TiO2/C and α-Fe2O3/C composite fiber electrodes. The α-Fe2O3/TiO2/C composite fibers also showed a superior cycling performance with a specific capacity of 340 mAh g−1 after 100 cycles at a current density of 100 mA g−1, compared to 61 mAh g−1 and 121 mAh g−1 for TiO2/C and α-Fe2O3/C composite electrodes, respectively. The improved electrochemical performance and the simple processing of these metal oxide/carbon composite fibers make them promising candidates for the next generation and cost-effective flexible binder-free anodes for LIBs.

Lithium-Ion Batteries (LIB) are growing in popularity for many applications. Much research has been focusing on battery performance improvement. However, few studies have overcome the disadvantages of the conventional LIB manufacturing processes. Laser cutting of electrodes has been applied. However, the effect of electrodes’ chemical, physical, and geometrical characteristics on the laser cutting has not been considered. This study proposes the effect of compression of cathode on laser cutting for lithium-ion batteries. The kerf width and top width of the specimens with laser irradiation are measured and the material removal energy is obtained. Observations of SEM photographs and absorptivity measurements are conducted. Increasing volume energies causes logarithmic increases in the kerf and top width. It is observed that the compressed cathode forms a wider kerf width than the uncompressed cathode under the same laser parameters. The top width of the uncompressed cathode is wider than the uncompressed cathode. The compression has a favorable effect on uniform cutting and selective removal of an active electrode. Full article

Prelithiation is an important strategy used to compensate for lithium loss during the formation of a solid electrolyte interface (SEI) layer and the other irreversible reactions at the first stage of electrochemical cycling. In this paper, we report a systematic study of thermal prelithiation of SiO2 particles with different sizes (6 nm, 20 nm, 300 nm and 3 μm). All four lithiated anodes (LixSi/Li2O composites) show improved performance over pristine SiO2. More interestingly, lithiated product from micron-sized SiO2 particle demonstrates optimum performance with a charge capacity of 1859 mAhg−1 initially and maintains above 1300 mAhg−1 for over 50 cycles.
