Summary Reactions between metals and H2O could provide high‐purity hydrogen gas for portable fuel cell. However, the initial reaction is typically hindered due to the existence of a dense outer oxide film. Herein, rapid generation of hydrogen following immersion of Mg in a solution of Mn(Ac)2 is examined. The formation of an Mg/Mn galvanic cell results in the destruction of an oxide film, inducing a continuous reaction between Mg, Mn, and water. Moreover, Mn is then oxidized back to Mn2+, illustrating that the metal further participates in the generation of hydrogen. The detected reaction rate varies from 37.5 to 55 mL g−1 minute−1, and the hydrogen volume is ~1000 mL at 35°C. Furthermore, the in‐situ potential changes with the generation of hydrogen, reflecting the fluctuation of the Mg2+ and OH− ions. Notably, the formation of flake‐type Mn or Mn(OH)2 facilitates the permeation of water, OH− ions, and the overflow of hydrogen. Conversely, the accumulation of square‐type Mg(OH)2 hinders permeation, lowering the hydrogen generation rate. The results of the present study provide new insights into the design of highly pure hydrogen generation systems by adjusting the solution composition.

The safety, affordability, and impressive electrochemical performance of many Zn-ion batteries (ZIBs) has recently triggered an overwhelming literature surge. As is typical for a new area, initial enthusiasm and high expectations have now been replaced by a more measured period of research that reaches deep into the underlying factors controlling electrochemical properties. Rather than battery metrics, this review focuses on fundamental aspects of the chemistry of ZIBs that are the least understood and on which there has been progress over the last few years. We provide guidance for future research regarding (1) the significant challenge of proton/Zn 2+ co-intercalation in aqueous media, (2) limitations to conversion chemistry that often accompanies ZIB electrochemistry, (3) positive aspects of facile Zn 2+ (de)intercalation in nonaqueous electrolytes and organic cathode materials, (4) the desolvation penalty at electrode-electrolyte interfaces, (5) solutions for controlling Zn dendritic growth, and (6) suggested electrochemistry protocols for the field.

etc., is essentially crucial to help combat these hazards and build a sustainable society. Among them, rechargeable battery has been regarded as a key technology. In the past decade, we have witnessed that the prevailing lithium-ion batteries (LIBs) made our society more portable, intelligent, and cleaner. [17][18][19] Nevertheless, the limited lithium resources and rising cost hinder their applications in the long run, especially in the field of large-scale stationary energy storage for renewable energy resources (e.g., solar, tide, and wind power). Thus, it is a huge stimulus for researchers to explore more sustainable rechargeable battery systems, which are expected to involve abundant and nontoxic metals to reduce the cost and impacts on environment.Diversified rechargeable batteries such as, the monovalent sodium-ion batteries (SIBs), [20][21][22][23][24] potassium-ion batteries (PIBs), [25][26][27] bivalent zinc-ion batteries (ZIBs), [28][29][30][31] magnesium-ion batteries (MIBs), [32][33][34][35] calcium-ion batteries (CIBs), [36][37][38][39] and trivalent aluminum-ion batteries (AIBs), [40][41][42] have emerged and shown great energy storage promise. As depicted in Figure 1a, those nonlithium metals are much more abundant than Li, especially Al, Ca, Na, K, and Mg, all of which rank the top-8 abundant elements in earth crust. For SIBs and PIBs, since Al would not form alloys with Na and K, Al foil can be used as anode collector, which further lowers the prices of SIBs and PIBs. On the other hand, the higher standard potential of Na/Na + (−2.71 V vs standard hydrogen electrode, SHE) and K/K + (−2.93 V) and their heavier atomic weights make energy densities of SIBs and PIBs intrinsically lower than that of LIBs. For multivalent-ion batteries, the multielectron transfer enables their volumetric capacities (e.g., 5857 and 8056 mA h cm −3 for Zn and Al, respectively) higher than that of Li (2042 mA h cm −3 ). [43,44] Additionally, the small cation radius of Zn 2+ (0.74 Å), Mg 2+ (0.72 Å), and Al 3+ (0.54 Å) indicate that many intercalation electrode materials typical in LIBs may be also potential hosts for reversible intercalation of these multivalent ions. Combining all the above merits, one can anticipate that these emerging rechargeable batteries would be considered as promising alternatives to LIBs.In quest of safe, cost-effective, and high-performance rechargeable batteries, two technical routes have been
