Extraordinary dendrite-free Li deposition on highly uniform facet wrinkled Cu substrates in carbonate electrolytes

Synergistic Effect of Cu2O Mesh Pattern on High‐Facet Cu Surface for Selective CO2 Electroreduction to Ethanol

“…In the cooling step, the high facet of wrinkle morphology formed with feature sizes of 250 nm in width and 10 nm in depth (Figure S3, Supporting Information) because of the thermal‐expansion energy difference between the graphene and the Cu surface. [ 18,33 ] The resultant graphene‐grown Cu was then transferred into a 200 °C preheated oven under ambient air and humidity condition for 40 min. The perfectly grown graphene area acts as a passivation layer during oxidization, preventing the penetration of oxygen molecules.…”

Insights on the work function of the current collector surface in anode-free lithium metal batteries

“…The recent works on the Cu facet effect on Li reversibility fall within this category although work function is not considered in these works. 21,22,39 Introducing a non-conducting lithiophilic seed on Cu surface with a high work function can be another feasible approach. [40][41][42] In addition, this work motivates the development of new current collector material with high work function and high lithiophilicity.…”

Uniform Lithium Deposition Induced by ZnFx(OH)y for High-Performance Sulfurized Polyacrylonitrile-Based Lithium-Sulfur Batteries

“…Copper foils, as anode current collectors, are important components of battery cells. However, the lithiophobic copper is not conducive to uniform nucleation and deposition of lithium metal [ 19 ], which will reduce the long-cycle stability of LMAs and shorten the cycle life of LMBs, especially in the case of limited lithium sources in battery cells ( Figure 1 a) [ 20 , 21 ]. Surface modification of Cu foils for lowering the energy barrier of Li metal nucleation and inducing uniform deposition of Li metal is an effective strategy to improve LMAs’ stability [ 22 , 23 ].…”
