Special Issue Information

Dear Colleagues,

Although lithium-ion batteries have been employed in electric vehicles, there is a continuous demand to increase the capacity of battery electrode materials, including both the anode and cathode. Anode materials are predominantly based on four storage mechanisms: intercalation, conversion reactions, alloying reactions, and lithium plating and stripping. The graphite anode, based on intercalation, is currently the only mature and safe anode material used for commercial lithium-ion batteries. However, it has a relatively low capacity of 372 mA h g–1. Many challenges lie in the pathway to a practical and safe anode for other anode materials. In this Special Issue, we seek papers on the design, synthesis, characterization, and mechanistic understanding of high-capacity anode materials for lithium-ion batteries.

Topics of interest include, but are not limited to, the following:

  • Lithium metal anodes;
  • Alloying-type anode materials;
  • Conversion reaction-type anode materials;
  • Carbon-based anode materials;
  • Composite anode materials, such as silicon-graphite composites;
  • Advanced and emerging characterizations of high-capacity anode materials;
  • Interface between solid electrolyte and anode materials;
  • Design of high-capacity anode materials using first-principle computation;
  • The modelling, simulation, and optimization of high-capacity anodes;
  • The advanced manufacturing of high-capacity anode materials;
  • The thermal safety of anode materials.

Poor cycling performance caused by massive volume expansion of silicon (Si) has always hindered the widespread application of silicon-based anode materials. Herein, bi-continuous silicon/carbon (Si/C) anode materials are prepared via magnesiothermic reduction of silica aerogels followed by pitch impregnation and carbonization. To fabricate the expected bi-continuous structure, mesoporous silica aerogel is selected as the raw material for magnesiothermic reduction. It is successfully reduced to mesoporous Si under the protection of NaCl. The as-obtained mesoporous Si is then injected with molten pitch via vacuuming, and the pitch is subsequently converted into carbon at a high temperature. The innovative point of this strategy is the construction of a bi-continuous structure, which features both Si and carbon with a cross-linked structure, which provides an area to accommodate the colossal volume change of Si. The pitch-derived carbon facilitates fast lithium ion transfer, thereby increasing the conductivity of the Si/C anode. It can also diminish direct contact between Si and the electrolyte, minimizing side reactions between them. The obtained bi-continuous Si/C anodes exhibit excellent electrochemical performance with a high initial discharge capacity of 1481.7 mAh g−1 at a current density of 300 mA g−1 and retaining as 813.5 mAh g−1 after 200 cycles and an improved initial Coulombic efficiency of 82%. The as-prepared bi-continuous Si/C anode may have great potential applications in high-performance lithium-ion batteries. Full article
