This review gives a detailed overview of the challenges in using sulfide solid electrolytes in all-solid-state lithium-sulfur batteries and discusses strategies to overcome them. First, the general description of the synthetic procedure of the sulfide solid electrolytes is given, including descriptions of the potential ways for improvement of the electrolyte properties, such as ionic conductivity and air and moisture resistance. This is followed by a review of the polymer binders and matrices that can enhance the sulfide solid electrolytes mechanical strength. Subsequently, the ways to ensure the chemical stability on the anode-solid electrolyte interface are described. Finally, prototypes of the all-solid-state Li-S batteries, created by using the combination of all above-mentioned methods, are discussed.

“…When the CuSnAl@Cu composite anode is matched with the LiFePO 4 cathode for LMBs, the Coulombic efficiency is as high as 99.6% after 300 cycles. Liu et al 138 constructed a ternary Li−Cu−Ag composite hosts by using a simple melt-rolling technique (Figure 8c). Lithiophilic Ag particles are able to promote Li deposition and growth at the bottom of the 3D current collector, preventing Li dendrite growth on the surface.…”

Lithium metal batteries have been attracting an abundance of attention recently as a powerful competitor of the next-generation advanced energy storage technologies. However, lithium dendrite formation can result in decreased battery lifespan and even safety issues, inhibiting the widespread application of lithium metal batteries. The conductive hosts of lithium metal anode are proven to be an effective method to prevent lithium dendrite formation and achieve outstanding electrochemical performance of lithium metal batteries. However, the surface deposition of Li ions decreases the utilization of the conductive host. Therefore, this Review introduces the design principle and recent advances to render the bottom-up deposition of a lithium metal anode. On one hand, conductivity and lithiophilicity gradient hosts are summarized to realize the “bottom-up” lithium deposition and efficiently limit the growth of lithium dendrites. On the other hand, the future prospects and challenges of host design associated with the “bottom-up” lithium deposition technique are discussed. This Review intends to provide novel insights for the development of gradient materials design and lithium metal batteries with long lifespan and high safety.

Li metal anode attracts tremendous attention in next-generation battery systems with high energy density, but volume change and dendritic growth limit its practical applications. Composite Li electrode can fundamentally suppress the volume effect and decrease the local current density, ensuring long-term cycling life. However, up to now, there is only limited success in preparing multifarious composite Li electrode, especially in thickness, posing great obstacles to further promoting its research and application. In this review, the thickness of composite Li electrode are strategically focussed upon and the merits and existing challenges of ultrathin composite Li electrode are evaluated. Meanwhile, the design principles and fundamental requirements for ultrathin composite Li electrode in the future are summarized and the existing cases related to this field are outlined as much as possible from synthetic chemistry, hoping it can serve as a handbook to provide a comprehensive understanding and guide reliable fabrication of advanced composite Li electrode. Challenges and opportunities regarding this burgeoning field are also critically evaluated at the end of this review.
