Shielded electric field-boosted lithiophilic Sites: A Janus interface toward stable lithium metal anodes

Present and future of functionalized Cu current collectors for stabilizing lithium metal anodes

“…To avoid the local accumulation of electrons and ions caused by the non-normalized lithiophilic sites, Luo et al prepared a composite skeleton comprising nanodiamond (ND) particle imbedded CuxO/Cu mesh (Fig. 15(d)) [226]. The insulating ND serving as an electric field shielding layer inhibits the accumulation of electron and the uneven conversion of lithiophilic sites effectively.…”

“…Furthermore, interfacial reinforcement to guide Li plating in a uniform manner is also important in promoting the deployment of the Li metal anode in LMBs. The latter has been achieved by using substrates with high Li affinity based on metal oxides that generate a lithiophilic Li 2 O matrix following the conversion reaction of M x O + 2Li + + 2e -→ xM + Li 2 O [10][11][12] or Li alloys that possess a high solid solubility with Li to lower the nucleation barrier of Li electrodeposits [13][14][15] . Despite these achievements, the low initial CEs caused by the conversion reaction of the metal oxides or the structural pulverization of the Li alloys still remain concerns for practical applications.…”

Li+ Solvation Mediated Interfacial Kinetic of Alloying Matrix for Stable Li Anodes

“…[11][12][13] In particular, as one of the most important parameters involved during the last development of Li protection techniques, Li affinity has shown great importance for the design of Li plating substrates, with aims of lowering the Li nucleation overpotential and improving the uniformity of Li deposition. The effectiveness of this concept has been demonstrated by using metal oxides that can generate the lithiophilic Li 2 O network during the initial lithiation process, [14][15][16] or using the metal materials that can alloy with Li. [17][18][19] However, the use of Li alloys is thought more profitable than the metal oxides, since it avoids the supplementary Li loss rooted in the Li 2 O conversion that decreases the initial CEs and energy density of LMBs.…”
