“…The lithium metal battery containing this separator ran for 6000 cycles at 2C without short circuit. [ 164 ] The proper charging protocol (>10 mA cm −2 ) of the battery made dendrites heal at high current density (Figure 10b , c ), which was attributed to the enhanced self‐diffusion of lithium atoms at high temperature arising from the high current density. [ 165 ] Furthermore, optimizing assembling process can also play a role in modifying the lithium anode, such as using a small‐area Cu electrode in Li||Cu battery.…”

With the low redox potential of −3.04 V (vs SHE) and ultrahigh theoretical capacity of 3862 mAh g −1 , lithium metal has been considered as promising anode material. However, lithium metal battery has ever suffered a trough in the past few decades due to its safety issues. Over the years, the limited energy density of the lithium-ion battery cannot meet the growing demands of the advanced energy storage devices. Therefore, lithium metal anodes receive renewed attention, which have the potential to achieve high-energy batteries. In this review, the history of the lithium anode is reviewed first. Then the failure mechanism of the lithium anode is analyzed, including dendrite, dead lithium, corrosion, and volume expansion of the lithium anode. Further, the strategies to alleviate the lithium anode issues in recent years are discussed emphatically. Eventually, remaining challenges of these strategies and possible research directions of lithium-anode modification are presented to inspire innovation of lithium anode.

“…Separators composed of a polymer-Cu-polymer triple layer were employed to dendrite detection, because a sharp voltage drop between Cu and Li anode could be recorded once dendrites reached the Cu layer but did not penetrate the whole separator (Figure 7C). 66 By introducing SiO 2 nanoparticles 67 or GO film 71 between two polymer membranes, Li dendrites that puncture the separator were eliminated through the chemical reaction with the middle layer (Figure 7D). Bifunctional separators exhibit obvious advantages in alkali metal-S and alkali metal-O 2 batteries because alkali metal anodes are protected from the corrosion of soluble polysulfides and dissolved O 2 .…”

Currently, high-energy rechargeable batteries are being intensively pursued to meet the increasing energy requirements of our modern life and industrial society. Alkali metals are considered some of the most promising anodes for nextgeneration high-energy batteries because of their superior theoretical specific capacities and low reduction potentials. Here, we provide an overview of the recent development of alkali metal anodes. First, we highlight that their high reactivity, unstable solid electrolyte interphase, dendrite formation, and huge volume change bring great challenges for the safety and lifespan of alkalimetal-based batteries. Then, we summarize various advanced strategiesincluding the micro-and/or nanostructuring of alkali metals, introduction of stable hosts, structural modification of current collectors, construction of artificial anode-electrolyte interfaces, separator modification, and electrolyte optimization-to address these challenges. Lastly, we present the remaining challenges and possible research directions for further developments.

Metallic lithium (Li) is a promising anode for Li-based batteries, owing to its high theoretical capacity and the low potential. However, the dendrites and high chemical activity of metallic Li limits its practical applications. To overcome these challenges, a fast-ionic conductor, antimony-doped lithium phosphate (Sbdoped Li 3 PO 4 ) artificial solid electrolyte interphase (SEI) layer, is directly coated on bare copper (Cu) foil by radio frequency (RF) magnetron sputtering, which can facilitate the uniform distribution of lithium ions, reduce the side reaction, and even inhibit the dendrite growth. As a result, the artificial Sb-doped Li 3 PO 4 SEI-modified Cu electrode renders a good coulombic efficiency of 97 % for approximately 285 cycles at current density of 1 mA/ cm 2 and over 700 h of stable cycles in a symmetric cell. The fabricated artificial SEI layers make the deposition of lithium occur more densely and the electrochemical impedance is smaller compared to the bare Cu electrode. This study will impact the general approach to realize and achieve nextgeneration high-energy-density lithium-metal batteries. electrode, the artificial Sb-doped Li 3 PO 4 SEI layer could mechanically suppresses Li dendrite and resulting in more uniform Li stripping and plating behavior investigated by SEM, EDS mapping and EIS measurement.
