ABSTRACT ZnO with good lithiophilicity has widely been employed to modify the lithiophobic substrates and facilitate uniform lithium (Li) deposition. The overpotential of ZnO‐derived Li anode during cycling depends on both LiZn 2 O products upon lithiation ZnO. However, striking differences in between would result a high cycling. In this research, Al 3 / n ( ≥ 1) hybrid layers were precisely fabricated by atomic layer deposition (ALD) regulate phase O/LiZn configuration—determining actual loading amount plating/stripping processes. Theoretically, adsorption energy E ) values LiZn/Li configuration are separately predicted as −2.789 −3.447 eV. comparison, LiZn, LiAlO 2, LiZn/LiAlO /Li /8ZnO calculated −2.899, −3.089, −3.208 eV, respectively.

Although layered oxides of LiNixCoyMnzO2 (NCM, x + y z = 1) are promising high energy density cathode materials, they still face significant challenges such as the cracks caused by anisotropic strain and poor structural thermal stability upon building high-performance rechargeable lithium-ion batteries (LIBs) for scale-up industrialization. Under this circumstance, La Mg elements theoretically experimentally introduced into NCM to modify primary particles synergistically lattice orientation regulation surface perovskite-phase coating. The synthesized La/Mg co-doped delivers a discharge-specific capacity 203 mAh g-1 at 0.1 C 126.2 10 (1C 200 mA g-1), which results from radial grain incorporating trace amount dopants, well enhancements on both ionic electronic conductivities. Further analysis discloses formation La-based perovskite protective layer surface, plays key role in stabilizing oxygen ions cycling increasing stabilities cathode. This one-step co-doping strategy provides rewarding avenue toward developing practical cathodes high-performance, durable Li batteries.

Abstract As the global energy structure transforms and renewable rapidly develops, rechargeable batteries are increasingly focus on high density, rapid charge/discharge rates, enhanced safety performance, particularly in extreme environments. Lithium metal (LMBs) have emerged as a significant research area recent years owing to capacity low electrochemical potential of lithium (Li). However, challenges, uncontrolled Li dendrite growth, unstable solid electrolyte interface separator puncture/interface incompatibility, greatly impact battery life lead failure, thus impeding commercialization. This review presents thorough analysis key challenges facing stable LMBs from multiple perspectives, alongside regulatory strategies. The methods include anode, interface, solid/liquid electrolytes, separators, pressure artificial intelligence. An in‐depth discussion operational mechanism, advantages/drawbacks is provided. Additionally, it offers succinct overview anticipated future trends challenges. A comprehensive numerous documents studies has been conducted summarize number published papers unique characteristics corresponding provides valuable recommendations for practical application other high‐energy‐density (Sodium, Potassium, Magnesium, Zinc), thereby contributing effectively implementation national strategic planning new sector.
