“…During the deconstruction of cycled cells to prepare samples for SEM imaging, we observed a thin black layer on the surface of the Li anode from the dilute LiPF 6 cell, whereas the surface of the Li anode from the HCE cell was shiny, similar to the surface of pristine Li. The darkening of the surface of Li metal in dilute LiPF 6 electrolytes is consistent with prior reports suggesting the presence of dendritic Li deposition and/or chemical reaction of the electrolyte with Li metal to form an SEI [67,68] …”

Lithium metal batteries suffer from dendrite formation and the associated safety hazards of thermal runaway reactions. In this study, we report the performances of a highly concentrated electrolyte (HCE) and a dilute LiPF6 electrolyte in lithium metal cells using LiNi0.8Co0.1Mn0.1O2. While the HCE exhibits lower bulk ionic conductivity than the dilute LiPF6 electrolyte, the cell conductivity is higher for the HCE system, indicating higher thermodynamic stability of the electrolyte against the electrodes. Full cell cycling demonstrates higher capacity for the HCE system, which declines as a function of cycle number due to the formation of decomposition products, similar to the dilute LiPF6 system. The origin of the enhanced performance is the higher stability of the HCE against a Li metal anode as compared to the dilute LiPF6 electrolyte. Cycling at higher temperatures further enhances the performance of the HCE, which is more thermally stable than the dilute LiPF6 electrolyte.

“…[ 95 ] Even at high current, the ex situ SEI prepared by immersing has obvious improvement on the battery properties. Li and co‐workers [ 90 ] immersed lithium anode in Mn(NO 3 ) 2 ‐containing carbonate electrolyte and gained nanotubes array growing on lithium anode (Figure 2c , d ). Nanotubes arrays that grew directly on the surface of the lithium anode contained LiF and Li 3 N, apparently enhancing the performance of Li||Cu battery, which stably operated for 150 cycles at high current density of 3 mA cm −2 and a CE of 94% was obtained (Although 94% falls far short of the standard of 99.9%, this is a valuable data considering that few studies measure CE at such high current densities).…”

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.

“…142 Compared to 1 st generation LMBs (pLMBs and LE-LMBs), LIBs are safe and long-lasting despite their lower energy density, which is compromised due to the replacement of Li-metal with a graphite analog. 143,144 Conversely, the new developments in LIBs include alternative materials such as alloying (e.g., silicon and tin) and conversion anodes [e.g., transition metal oxides (TMOs)] as close competitors to graphite for enhancing the energy density. 145,146 From a practical perspective, since the commercialization in 1991, the configuration of state-of-the-art LIB has not undergone major changes.…”
