MnO2 nanosheet modified N, P co-doping carbon nanofibers on carbon cloth as lithiophilic host to construct high-performance anodes for Li metal batteries

Organic‐inorganic Hybrid Perovskite‐Based Light‐Assisted Li‐oxygen Battery with Low Overpotential

“…[1,2] However, the development of Lioxygen battery still faces some challenges such as the high charge overpotential, poor rate capability, and low cyclic stability due to the electrolyte decomposition as well as the side reaction with cathode or anode materials, which are closely related to the chemical reaction kinetics in the Li-oxygen battery. [3][4][5][6] Thus, the modification of the electrochemical reaction, mainly associated with oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) process, via catalysts is crucial not only for the optimization of charging/discharge voltage but also for the battery's cycling performance and lifespan. [7] Different from traditional catalysts, such as noble metals and oxides, aiming to modify the reactant's adsorption energy, reaction paths, or product morphology, photocatalysts exhibit photo-generated carriers and have been proven to be effective in improving Li-oxygen battery performance.…”

Advances in research on the inhibitory effect of 3D current collector structures for lithium dendrites

“…Liu et al modified MnO 2 nanosheets coated with nitrogen (N) and phosphorus (P) co-doped carbon nanofibers (MnO 2 -NPC-CC) on carbon cloth by electrodeposition. 87 All three elements, N, P, and Mn are lithiophilic, so doping in carbon cloth reduces the nucleation barrier to facilitate uniform lithium deposition/dissolution. Li-MnO 2 @NPC-CC symmetric cell, after 20 cycles at a fixed capacity of 1.0 mA h cm −2 and a current density of 1.0 mA cm −2 , the electrode surface was smooth and dense without lithium dendrite formation (Fig.…”

Co–Mo alloy oxide decorated carbon cloth as lithium host for dendrite-free lithium metal anode

“…Such a phenomenon could be ascribed to the poor lithiophilic nature of pure carbon. 28 Therefore, lithiophilic materials (MnO 2 , 33 ZnO, 34 SnO 2 , 35 Au (ref. 30)) were used to change the surface lithiophilicity to reduce the nucleation overpotential.…”
