Lithiophobic-lithiophilic composite architecture through co-deposition technology toward high-performance lithium metal batteries

Recent Progress in Designing Stable Composite Lithium Anodes with Improved Wettability

“…[7][8][9][10] To overcome these obstacles, progress has been made through the optimization of organic electrolytes, [11][12][13] the creation of protective interface layers, [14][15][16] solid electrolyte exploration, [17][18][19] and 3D-designed hosts for Li metal. [20][21][22][23][24] 3D Li hosts effectively homogenize the Li-ion flux, regulate uniform Li nucleation and growth, stabilize Li/electrolyte interfaces, and prevent dimensional variation of the electrode due to their high specific surface area and porous structures. [25][26][27] Nevertheless, there are great technical challenges associated with encapsulating metallic Li inside 3D scaffolds.…”

Strategies in Structure and Electrolyte Design for High‐Performance Lithium Metal Batteries

“…Surface coating on 3D metals with lithiophilic materials to form stable Li‐based alloys and Li‐based polymers is another effective strategy to improve the electrochemical performance of Li metal anode. Due to the excellent lithiophilicity, Zn, [ 100–102 ] Sn, [ 103 ] Cu x O, [ 104,105 ] and ZnO [ 106–108 ] are commonly used as coating mediums for the fabrication of Li‐based alloys through the direct chemical reaction with metallic Li (Figure 8b,c). The formed Li‐based alloys possess significantly higher strength and modulus than bare metallic Li, which can effectively restrain the growth of Li dendrites.…”

Three dimensional porous frameworks for lithium dendrite suppression

“…By making use of the lithiophilic/lithiophobic materials and arranging them carefully, it is possible to regulate the Li deposition more efficiently [134][135][136] . Pu et al proposed a "top-growth" mode where Li deposition preferentially began from the anode/separator interfaces, which would cause direct dendrite growth and penetrate the separator [137] .…”
