Abstract

Abstract: The great demand for high‐energy‐density batteries has driven intensive research on the Li–S battery due to its high theoretical energy density. Consequently, considerable progress in Li–S batteries is achieved, although the lithium anode material is still challenging in terms of lithium dendrites and its unstable interface with electrolyte, impeding the practical application of the Li–S battery. Li2 S‐based Li‐ion sulfur batteries (LISBs), which employ lithium‐metal‐free anodes, are a convenient and effective way to avoid the use of lithium metal for the realization of practical Li–S batteries. Over the past decade, studies on LISBs are carried out to optimize their performance. Herein, the research progress and challenges of LISBs are reviewed. Several important aspects of LISBs, including their working principle, the physicochemical properties of Li2 S, Li2 S cathode material composites, LISBs full batteries, and electrolyte for Li2 S cathode, are extensively discussed. In particular, the activation barrier in the initial charge process is fundamentally analyzed and the mechanism is discussed in detail, based on previous reports. Finally, perspectives on the future direction of the research of LISBs are proposed. Abstract : The Li2 S‐based Li‐ion sulfur batteries system has high energy density and high safety due to the depletion of the lithium metal anode. This Review systematically discusses Li2 S composite cathodes, non‐lithium anodes, electrolytes and full cell configuration of the Li2 S‐based Li‐ion sulfur batteries. Some perspectives are proposed to further develop this battery system and to reach the practical high‐energy batteries.
