“…However, when considering the assembled full cells by using proton cathodes, the achieved rate and cycling stability of the reported proton full cells are still inferior to some high-performance aqueous batteries. ,, For instance, Ji and co-workers’ full cells with CuFe-TBA/WO 3 and CuFe-TBA/MoO 3 battery systems showed a poor cycle life with a capacity retention of 74% and 85% after 1000 cycles, respectively, although outstanding reactions still occurred in the cathodes. , Wang and co-workers proposed a MnO 2 /PTO proton full battery that delivered a high power density of 30.8 kW kg –1 , but with a severe capacity decay of 43% after 5000 cycles . In fact, only a limited number of APB full cells have been successfully demonstrated to date, which is primarily ascribed to the lack of stable proton electrodes in acidic electrolytes. ,,− Therefore, it is very necessary to explore novel proton full cells with excellent performance for exerting the advantages of both proton cathode and anode, which are of paramount importance to their realistic applications.…”

Aqueous proton batteries are regarded as one of the most promising energy technologies for next-generation grid storage due to the distinctive merits of H+ charge carriers with small ionic radius and light weight. Various materials have been explored for aqueous proton batteries; however, their full batteries show undesirable electrochemical performance with limited rate capability and cycling stability. Here we introduce a novel aqueous proton full battery that shows remarkable rate capability, cycling stability, and ultralow temperature performance, which is driven by a hydrogen gas anode and a Prussian blue analogue cathode in a concentrated phosphoric acid electrolyte. Its operation involves hydrogen evolution/oxidation redox reactions on the anode and H+ insertion/extraction reactions on the cathode, in parallel with the ideal transfer of only H+ between these two electrodes. The fabricated aqueous hydrogen gas–proton battery exhibits an unprecedented charge/discharge capability of up to 960 C with a superior power density of 36.5 kW kg–1, along with an ultralong cycle life of over 0.35 million cycles. Furthermore, this hydrogen gas–proton battery is able to work well at an ultralow temperature of −80 °C with 54% of its room-temperature capacity and under −60 °C with a stable cycle life of 1150 cycles. This work provides new opportunities to construct aqueous proton batteries with high performance in extreme conditions for large-scale energy storage.

“…Recently, we have successfully demonstrated a new battery chemistry for the grid-scale energy storage by the coupling of electrocatalytic hydrogen gas anode with transition-metal oxide/hydroxide cathodes. , Taking advantages of the low overpotential, fast kinetics, and high stability of the hydrogen gas anode governed by hydrogen evolution and oxidation reactions (HER and HOR), , the demonstrated manganese–hydrogen and nickel–hydrogen batteries showed reasonable energy density, fast charge/discharge rates, and long cycle life. Their advantages were also compared with other rechargeable hydrogen technologies such as formate-based rechargeable hydrogen batteries , and proton-coupled electron transfer hydrogen batteries . The exciting characteristics of the rechargeable hydrogen batteries inspire us to explore new battery systems to enrich the hydrogen battery chemistry.…”

“…The high average CE of ∼99.5% for the entire cycling duration indicates the efficient utilization of the electrical charge. Moreover, the LMO-H cell exhibits superior rate and cycling performance than some other hydrogen coupled batteries ,, (Table S1). The capacity decay of the LMO-H cell is derived from the instability of the LMO cathode, which is a well-known phenomenon involving the dissolution of Mn or the Jahn–Teller distortion of the LMO structure .…”

Rechargeable hydrogen gas batteries show promises for the integration of renewable yet intermittent solar and wind electricity into the grid energy storage. Here, we describe a rechargeable, high-rate, and long-life hydrogen gas battery that exploits a nanostructured lithium manganese oxide cathode and a hydrogen gas anode in an aqueous electrolyte. The proposed lithium manganese oxide-hydrogen battery shows a discharge potential of ∼1.3 V, a remarkable rate of 50 C with Coulombic efficiency of ∼99.8%, and a robust cycle life. A systematic electrochemical study demonstrates the significance of the electrocatalytic hydrogen gas anode and reveals the charge storage mechanism of the lithium manganese oxide-hydrogen battery. This work provides opportunities for the development of new rechargeable hydrogen batteries for the future grid-scale energy storage.

In this paper, the authors have investigated a suitable material for rechargeable lithium-ion battery, which poses a challenge to the researchers in the search for alternate electrode materials. An analysis of humidity as well as nitrite sensing application, the potential of this material has been reported. MoO 3 can reversibly store large amounts of Li; it can be a potential alternative electrode among currently existing anode materials. The self-assembled hexagonal rods of h-MoO 3 as flowers have been synthesized via a simple and facile low temperature reflux method. The measured mean crystallite size and band gap (E g ) of h-MoO 3 hexagonal crystalline structure are 52 nm and 3.48 eV as per the XRD and UV-vis DRS studies respectively. Hexagonal rod shaped h-MoO 3 anodes exhibit remarkable electrochemical stability, recyclability, high rate capability; which produce the initial discharge capacity of 1869 mAh g −1 and then the capacity retained around 619 mAh g −1 at 100 th cycle of chargedischarge profile by applying the current rate of C/15. This simple and novel material synthesis provides unique morphology of hexagonal rods shaped h-MoO 3 flowers; and this scheme provides the facile pathways which enable the ease of electron transportation. The sensing activity of modified glassy electrode of h-MoO 3 has shown a limit of detection of 0.196 μM for 1 mM nitrite sensing. It also showed high humidity sensing response of 97.9 %, and indicated that the h-MoO 3 flowery material is well suitable for industrial applications.
