Special Issue Information

Dear Colleagues,

High-energy-density lithium metal batteries are promising for energy storage applications. However, the uncontrollable electrolyte degradation and notorious formation of dendrites can cause the failure batteries upon cycling. So far, rare reports have demonstrated the achievement of Li Coulombic efficiency (CE) above 99.9% over 1000 cycles. The important role of electrolytes, solid electrolyte interphases, Li morphology, and their interrelationships requires a deeper understanding. Therefore, it is necessary to have a clear overview of the development of current advances in lithium metal batteries. This Special Issue is intended to bring the latest updates and prospects of lithium metal batteries. Potential topics include but are not limited to:

  • Electrolyte design for lithium metal batteries;
  • Interfacial engineering for Li metal protection;
  • Theoretical understanding of interfacial reactions;
  • Advanced characterizations;
  • New test protocol for Li metal.

Lithium (Li) metal is perceived as the “holy grail” of anodes for secondary batteries due to its innate merits. Regrettably, the commercial application of Li metal anodes (LMAs) has been hampered by problems derived from the uncontrollable growth of Li dendrites, which could result in formation of short-circuits, thereby leading to fatal safety accidents. Here, a three-dimensional lithiophilic gold (Au)-coated copper (Cu) pentagonal pyramid array (Au@CuPPA) is constructed on planar Cu foil via electrodeposition followed by a chemical reduction method. Owing to the features of the lithiophilic layer and 3D porous structure, the proposed Au@CuPPA can not only facilitate Li-ion migration and charge transfer, but also effectively diminish the nucleation overpotential. Consequently, an even and steady Li plating/stripping process for up to 460 h and with a charge capacity of 3 mAh cm−2 is accomplished by using the Au@CuPPA current collector. The Li@Au@CuPPA|LiFePO4 full cell achieves a high Coulombic efficiency (CE) of 99.4% for 150 cycles at 0.5 C with a capacity retention of 92.4%. Full article

An Li metal anode has been proposed as a promising candidate for high energy density electrode material. However, the direct use of Li metal can lead to uncontrollable dendrite growth and massive volume expansion, which generates severe safety hazards and hinders practical application. Herein, we developed a novel Li anode by thermal infusion into three-dimensional (3D) carbon cloth (CC) modified with lithiophilic CuO nanorod arrays (denoted as Li@CuO−CC). The 3D CC offers sufficient space for Li storage and adequate electrolyte/electrode contact for fast charge transfer. The uniformly distributed CuO nanorod arrays can improve the lithiophilicity of CC and redistribute the Li-ion flux on the substrate, leading to uniform Li stripping/plating behavior. As a result, the Li@CuO−CC electrode exhibits a dendrite-free feature and superior cycling performance over 1000 h with low overpotential (12 mV) at a current density of 1 mA cm−2 in the symmetrical cell without significant fluctuations. When coupled with an LiFePO4 cathode, the full cell displays high specific capacity (133.8 mAh g−1 at 1 C), outstanding rate performance, and cycle stability (78.7% capacity retention after 600 cycles at 1 C). This work opens a new approach for the development of construction of an advanced anode for Li metal batteries. Full article
