Modifying surface of Ni foam via hierarchical lithiophilic nanoarrays for stable lithium metal anodes

Structural Design of 3D Current Collectors for Lithium Metal Anodes: A Review

“…[23] Thus, in order to improve the electroactive surface area of Cu foil, Zhu and coworkers [23] reported 3D-CuO nanowires array on commercial Cu foil which could be mass-produced via a facile wet chemical method (Figure 5b-d Surface coating of metal compound: In addition, a lithiophilic layer coating on the surface of metal skeletons can increase the Li affinity to guide the Li uniform deposition. Our group [24] introduced a scaffold constructed by surface growth of 3D lithiophilic acicular CoNiO 2 on the porous NF (Figure 6a). The empty tetrahedral positions of CoNiO 2 as lithiophilic sites can provide a 3D lattice for Li-ion diffusion and electron conversion, inhibiting the formation of dendritic Li during cycling.…”

Co/Li2S of chemical confinement decorated electrochemically stable Co(OH)F nanoarrays enabling dendrite-free flexible 3D Li anodes

“…As a result, they are unable to effectively regulate the subsequent Li plating/stripping process. 31,32 Therefore, constructing composite nanoarrays with an electrochemically stable inner core and a lithiophilic outer shell on a 3D skeleton is conducive to providing a stable structure and promoting uniform Li deposition. 33…”

Electrode/electrolyte additives for practical sodium-ion batteries: a mini review

“…In general, the additives used in electrolytes stabilize the formation of the solid electrolyte interphase (SEI) and the cathode electrolyte interphase (CEI) to enhance the electrochemical performance of the batteries and subsequently improve cell safety. [50][51][52][53] There are many fundamental requirements for the SEI layer, such as providing a path for ion transfer, protecting electrodes from solvent molecules and being stable during the charge-discharge processes. Similar to the SEI layer, the purpose of CEI are to prevent the dissolution of active material into the electrolyte and suppressing the further oxidation of electrolyte components.…”
