“…The high price, limited resources, and safety issues are still major concerns of lithium-ion batteries, although they have been widely applied in portable electronic devices, and electric vehicles in recent years. [1][2][3][4] In this regard, rechargeable aqueous batteries with natural abundance and non-flammable properties have attracted much attention, such as magnesium ion batteries, [5][6][7] aluminum ion batteries, [8][9][10] sodium-ion battery, [11] and zinc ion batteries (ZIBs). [12][13][14] Comparing with other aqueous metal batteries, zinc (Zn) metal as the anode for aqueous batteries has been widely studied due to its high theoretical capacity (820 mAh g −1 ), low redox potential (−0.76 V versus standard hydrogen electrode) and excellent water compatibility.…”

The detrimental hydrogen evolution side reaction is one of the major issues hindering the commercialization of Zn metal anode in high-safety and lowcost rechargeable aqueous batteries. Herein, the authors present a Sn alloying approach to effectively inhibit the hydrogen evolution and dendrite growth of the Zn metal anode. Through in situ monitoring of the hydrogen production during repeated plating/stripping tests, it is quantitatively demonstrated that the hydrogen evolution of alloy electrode with appropriate Sn amount is only half of that of pure Zn electrode. Furthermore, the Sn alloying allows for favorable Zn nucleation sites, lowering the Zn nucleation energy barrier and promoting more uniform Zn deposition. The Zn-Sn alloy electrode offers muchimproved plating/stripping cycling, that is, over 240 h at 5 mA cm −2 and 35.2% depth of discharge. This work provides a practically viable strategy to stabilize Zn metal electrode in rechargeable aqueous batteries.

Growth Mechanism of Micro/Nano Metal Dendrites and Cumulative Strategies for Countering Its Impacts in Metal Ion Batteries: A Review

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.

“…[5][6][7][8][9][10][11][12] However, as a crucial part of aluminum-based batteries, Al anodes have some challenging issues that need to be properly addressed, such as the dendrite growth, insulative oxide film, and corrosion accompanying hydrogen evolution in an ionic liquid (IL) electrolyte. [13][14][15][16] Conventional Al anodes have the limitation of dendrite formation due to unstable reversible deposition, leading to safety concerns when piercing the separator and causing deteriorative capacity and cycling life. 14,[17][18][19] In conventional aluminum-metal batteries with IL electrolytes, the ionic and electron passivating oxide layer hinders the connection between the electrolytes and the Al anodes and decreases the electrochemical activity of Al plating/stripping.…”

Aluminum-metal batteries show great potential as next-generation energy storage due to their abundant resources and intrinsic safety. However, the crucial limitations of metallic Al anodes, such as dendrite and corrosion problems in conventional aluminum-metal batteries, remain challenging and elusive. Here, we report a novel electrodeposition strategy to prepare an optimized 3D Al anode on carbon cloth with an uniform deposition morphology, low local current density, and mitigatory volume change. The symmetrical cells with the 3D Al anode show superior stable cycling (>450 h) and low-voltage hysteresis (~170 mV) at 0.5 mA cm −2 . High reversibility (~99.7%) is achieved for the Al plating/stripping. The graphite | | Al-4/CC full batteries show a long lifespan of 800 cycles with 54 mAh g −1 capacity at a high current density of 1000 mA g −1 , benefiting from the high capacitive-controlled distribution. This study proposes a novel strategy to design 3D Al anodes for metallic-Al-based batteries by eliminating the problems of planar Al anodes and realizing the potential applications of aluminum-graphite batteries.
