“…Based on this method, the single doping of oxygen (O) and codoping of O and boron (B) are proven to be the most effective lithiophilic strategies. 93 Xie et al 96 Thus, the Li metal anode exhibits superior cycling performance with 700 h stable cycles at a current density of 1 mA cm −2 and at a capacity of 1 mAh cm −2 . In addition, good capacity retention and high Coulombic efficiency can be achieved in the OBHcCs@Li/LiFePO 4 full cell.…”

Metallic lithium (Li) is considered the “Holy Grail” anode material for the next‐generation of Li batteries with high energy density owing to the extraordinary theoretical specific capacity and the lowest negative electrochemical potential. However, owing to inhomogeneous Li‐ion flux, Li anodes undergo uncontrollable Li deposition, leading to limited power output and practical applications. Carbon materials and their composites with controllable structures and properties have received extensive attention to guide the homogeneous growth of Li to achieve high‐performance Li anodes. In this review, the correlation between the behavior of Li anode and the properties of carbon materials is proposed. Subsequently, we review emerging strategies for rationally designing high‐performance Li anodes with carbon materials, including interface engineering (stabilizing solid electrolyte interphase layer and other functionalized interfacial layer) and architecture design of host carbon (constructing three‐dimension structure, preparing hollow structure, introducing lithiophilic sites, optimizing geometric effects, and compositing with Li). Based on the insights, some prospects on critical challenges and possible future research directions in this field are concluded. It is anticipated that further innovative works on the fundamental chemistry and theoretical research of Li anodes are needed.

“…[31] The similar N-, S-, O-doped carbon substrates are also beneficial for smooth Na deposition. [32][33][34][35][36] In order to achieve large specific areas and improved interfacial properties, hierarchical structured carbon substrate is subtly designed. For example, Yue et al designed the carbon sphere/carbon fiber current collector with abundant defects and "gradient sodiophilic" properties.…”

Sodium metal batteries (SMBs) have been widely studied owing to their relatively high energy density and abundant resources. However, they still need systematic improvement to fulfill the harsh operating conditions for their commercialization. In this review, we summarize the recent progress in SMBs in terms of sodium anode modification, electrolyte exploration, and cathode design. Firstly, we give an overview of the current challenges facing Na metal anodes and the corresponding solutions. Then, the traditional liquid electrolytes and the prospective solid electrolytes for SMBs are summarized. In addition, insertion‐ and conversion‐type cathode materials are introduced. Finally, an outlook for the future of practical SMBs is provided.

“…Graphite is conventionally used as an anode, with a working potential of ~0.1 V vs. Li/Li + , due to its low cost and high cycle life, but it has limitations in terms of its specific capacity (372 mAh g −1 ), along with the intercalation of one metal atom for six carbon atoms (LiC6) [98,99]. Instead, Li metal foil as an anode can potentially increase the specific capacity to 1150 Wh Kg −1 , competing with gasoline [100][101][102][103].…”

Metal-ion batteries are capable of delivering high energy density with a longer lifespan. However, they are subject to several issues limiting their utilization. One critical impediment is the budding and extension of solid protuberances on the anodic surface, which hinders the cell functionalities. These protuberances expand continuously during the cyclic processes, extending through the separator sheath and leading to electrical shorting. The progression of a protrusion relies on a number of in situ and ex situ factors that can be evaluated theoretically through modeling or via laboratory experimentation. However, it is essential to identify the dynamics and mechanism of protrusion outgrowth. This review article explores recent advances in alleviating metal dendrites in battery systems, specifically alkali metals. In detail, we address the challenges associated with battery breakdown, including the underlying mechanism of dendrite generation and swelling. We discuss the feasible solutions to mitigate the dendrites, as well as their pros and cons, highlighting future research directions. It is of great importance to analyze dendrite suppression within a pragmatic framework with synergy in order to discover a unique solution to ensure the viability of present (Li) and future-generation batteries (Na and K) for commercial use.
