“…The Li metal anode coated with glass fiber layers presented an impressive cycle performance at a current density of as high as 10 mA cm −2 . A low‐weight 3D Al 2 O 3 network has been reported by Duan and co‐workers as an artificial layer to stabilize Li deposition . Lithiophilic Al 2 O 3 coating on a Cu electrode enabled heterogeneous nucleation with the lowest overpotential during Li metal deposition, which might lead to preferential nucleation behavior near the contact area, and subsequently, uniform and stable Li deposition.…”

Lithium (Li) metal is considered as the most promising anode material for rechargeable high‐energy batteries. Nevertheless, the practical implement of Li anodes is significantly hindered by the growth of Li dendrites, which can cause severe safety issues. To inhibit the formation of Li dendrites, coating an artificial layer on the Li metal anode has been shown to be a facile and effective approach. This review mainly focuses on recent advances in artificial layers for stable Li metal anodes. It summarizes the progress in this area and discusses the different types of artificial layers according to their mechanisms for Li dendrite inhibition, including regulation of uniform deposition of Li metal and suppression of Li dendrite growth. By doing this, it is hoped that this contribution will provide instructional guidance for the future design of new artificial layers.

“…[85] The tortuous pores of the media drastically reduced the local Li-ion flux and tuned the plating performance of the battery, resulting in an ultralong cycling life of over 3000 h. Recently, Tian et al developed a lightweight, hollow 3D Al 2 O 3 network that served as the artificial layer (Figure 6d). [86] The lithiophilic properties of the rigid layer ensured a dendrite-free deposition of Li ions on the current collector, which resulted in a long-term stability with lower hysteresis (Figure 6e).

Li-O 2) batteries with high theoretical energy densities offer considerable potential for a new generation of energy storage technology. [1] In 1996, the first nonaqueous Li-O 2 battery was introduced with a polymer organic electrolyte and a carbon-cobalt composite cathode by Abraham and Jiang. [2] This was followed by the verification of the rechargeability of Li-O 2 batteries with manganese dioxide-super S cathodes for over 50 cycles by Bruce and co-workers, [3] after which nonaqueous Li-O 2 batteries received substantial research attention worldwide. A typical nonaqueous Li-O 2 battery includes a Li metal anode, an aprotic electrolyte and an O 2 cathode. It operates according to the reaction 2Li + O 2 ↔ Li 2 O 2 (2.96 V vs Li/Li +), in which O 2 is reduced to form Li 2 O 2 on the cathode during discharging and Li 2 O 2 is decomposed to O 2 and Li + through a reversible charging process. In this way, the battery delivers exceptional theoretical energy density of ≈3600 Wh kg −1. [4] This report is centered on nonaqueous Li-O 2 batteries, and the use of the term "Li-O 2 batteries" mentioned below represents "nonaqueous Li-O 2 batteries." To date, enormous progress has been achieved in the understanding and application of high-performance Li-O 2 batteries, however, their low practical discharge capacity, poor rate capability, low round-trip efficiency, and inferior cycling stability have greatly blocked their practical applications. The current major scientific and technical challenges of Li-O 2 batteries can be summarized as follows. 1) The slow kinetics of formation and decomposition of the discharge products lead to poor rate capability and low round-trip efficiency. 2) Cathode corrosion and electrolyte decomposition due to the attack by the discharge intermediates such as superoxide species, giving rise to poor cycling stability. 3) Pore clogging on the cathode arising from the stacking of insulated, insoluble discharge products blocks the mass transfer and oxygen/Li + diffusion, limiting the capacity and degrading the cycling performance. 4) The inevitable side reactions between the highly reactive Li anode and the organic electrolyte, crossover O 2 , CO 2 , etc., and the redox mediators (RMs), give rise to premature battery death. [1a,5] 5) The unavoidable Li dendrites caused by uncontrollable deposition of lithium, as well as the risk of collapse of the lithium anode due to the volume change during iterative plating/stripping processes, increase the probability of safety problems. [6] Consequently, the slow kinetics of Li 2 O 2 Porous materials possessing high surface area, large pore volume, tunable pore structure, superior tailorability, and dimensional effect have been widely applied as components of lithium-oxygen (Li-O 2) batteries. Herein, the theoretical foundation of the porous materials applied in Li-O 2 batteries is provided, based on the present understanding of the battery mechanism and the challenges and advantageous qualities of porous materials. Furthermore, recent progress in porous material...

Electrification has great impacts on our modern society. To electrify future transportation, state‐of‐the‐art lithium‐ion batteries (LIBs) are still not sufficient in multiple aspects including cost, energy density, lifespan, and safety. To this end, next‐generation high‐energy LIBs and beyond are highly regarded. In this regard, high‐capacity anodes are undergoing intensive investigation, such as silicon, SnO2, and lithium metal. However, such anode materials are commonly experiencing large volume changes and related issues, which are reflected on mechanical degradation, capacity fading, low efficiency, and unsatisfactory lifetime. To address these challenges, many technical strategies have been investigated. In the past decade, atomic layer deposition (ALD) has emerged as a new promising technique enabling atomic‐scale surface modification and nanoscale design of high‐capacity anodes for high performance. In this review, recent ALD studies on developing high‐capacity anodes for LIBs and beyond are thoroughly summarized. In addition, ALD strategies and their effectiveness in pursing high‐energy LIBs and beyond are discussed. Particularly, we highlighted the latest advances of ALD for addressing the notorious issues associated with Li metal anodes. It is expected that this work will promote the applications of ALD in new battery systems.
