Special Issue Information

Dear Colleagues,

The rechargeable lithium metal battery, as the ‘holy grail’ in battery technology, has ultrahigh theoretical capacity (3862 mAh g–1) and great electrochemical potential (–3.04 V vs. SHE). Therefore, researchers from academia and industry are dedicating great efforts for batteries toward a mature technology. However, lithium-metal corrosion, dendrite formation/growth, volume expansion, and inventory loss lead to severe safety issues and capacity fading. To address these concerns, this edition discusses the suitability of rechargeable lithium-metal batteries for applications and characterizations. Potential topics for the Special Issue include but are not limited to the following:

  • All-solid-state lithium metal battery;
  • Advanced characterizations for lithium-metal batteries;
  • Liquid electrolyte;
  • Lithium metal anode protection;
  • Artificial solid–electrolyte interface (SEI);
  • High-capacity cathode for lithium-metal batteries;
  • Lithium metal electrostripping/electroplating mechanisms;
  • Lithium host.

It continues to be a challenge to design innovative NiCoP composite anode materials to further improve rate capacity. In this work, bimetallic flower-like NiCoP encapsulated in an N-doped carbon shell (designated as NiCoP@NC) as a high-rate capable anode material for lithium-ion batteries (LIBs) was successfully designed and synthesized. The novel structure design combines the advantages of flower-like NiCoP (core) and N-doped carbon (shell). Flower-like NiCoP offers numerous interface and redox reaction sites for improving lithium storage, while the N-doped carbon shell effectively buffers volume expansion and enhances electrical conductivity. The synergistic effect between NiCoP and the N-doped carbon shell proposes a marvelous high-rate capacity (320 mA h/g even at 5 A/g) and a good cycle life with high reversible capacity (369.8 mA h/g for 700 cycles at 3 A/g with 81% retention). An investigation of kinetics performance shows that the introduction of the N-doped carbon shell enhances the charge transfer, and the pseudocapacitive behavior dominates the rapid Li+ storage of the NiCoP@NC electrode.

NASICON-type Li1.5Al0.5Ge1.5(PO4)3 (LAGP) is a remarkable solid-state electrolyte due to its high ionic conductivity and excellent air stability. However, the weak LAGP|Li interfacial compatibility (e.g., chemical instability of LAGP with Li metal and lithium dendrite growth) limits its practical application. Herein, an ultrathin CuS layer was fabricated on the surface of the LAGP electrolyte by magnetron sputtering (MS). Then, an in situ Li2S/Cu nano-layer formed via the conversion reaction between CuS and molten Li was constructed at the LAGP|Li interface. The Li2S/Cu nano-layer enables effective hindering of the reduction reactions of LAGP with Li metals and the suppression of lithium dendrite growth. The assembled Li symmetric battery with the Li2S/Cu@LAGP electrolyte shows a promising critical current density (CCD) of 0.6 mA cm−2 and a steady battery operation for over 700 h. Furthermore, the full LiFePO4 battery comprising the Li2S/Cu@LAGP electrolyte shows excellent capacity retention of 94.5% after 100 cycles, providing an appropriate interface modification strategy for all-solid-state Li metal batteries.

Li metal has emerged as a promising anode material for high energy density batteries, due to its low electrochemical potential and high specific capacity of 3860 mAh·g−1. These characteristics make it an attractive choice for electric vehicles and power grids. However, Li-metal batteries are plagued by dendrite issues stemming from the high reactivity of Li metal, which can ultimately result in battery failure or even safety concerns. To overcome this challenge, various strategies have been proposed to prevent dendrite formation and enhance the safety of Li-metal batteries. This review critically examines the recent progress in the development of dendrite-free Li-metal batteries, with a particular emphasis on advanced approaches of 3D Li metal host construction. Our goal is to provide a comprehensive overview of the 3D hosts for suppressing Li dendrites and to offer guidance for the future development of superior Li metal batteries. Full article
