Summary: Aqueous zinc ion batteries are gaining popularity for large-scale energy storage due to their safety, cost, and scalability. However, the limited cyclability and poor calendar life of vanadium oxide-based batteries hinder their practical adoption. This study reveals that the formation of an inactive zinc pyrovanadate phase on the cathode surface is the main cause of limited sustainability and is correlated with the corrosion of the zinc metal anode. By controlling the pH and using an amalgamated zinc anode, the cyclability and lifetime of the batteries can be significantly improved.

Summary: Three different crystalline forms of Mn3O4 were successfully prepared using a liquid phase method with different additives. The effects of the additives on the morphology, phase composition, surface characteristics, specific surface area, and electrochemical properties of manganese oxides were investigated. It was found that the rod-type Mn3O4 prepared with ammonia water, anhydrous ethanol, and cetylmethyl ammonium bromide as additives exhibited excellent electrochemical performance and a high specific capacity, making it a promising candidate for lithium-ion battery anode materials.

Summary: Carbon capture and utilization (CCU) is a key technology for mitigating climate change. One approach, reactive carbon capture (RCC), involves capturing and concentrating CO2 using a capture medium and then transforming it into a fuel or chemical. In this study, a combination of modeling and experimental methods reveals that dissolved CO2 is primarily consumed during the electrochemical reduction of CO2 capture solutions on silver electrodes.

Summary: EIS is an important diagnostic tool, but identifying pseudo peaks decoded by the DRT/DDC method remains a challenge. This study presents new insights from the perspective of symmetry, categorizing pseudo peaks into three types and quantitatively evaluating the decoded peaks. The solution to pseudo peaks decoded by the DRT/DDC method was validated through simulated impedance spectra.

Summary: High-quality protonated Ni-doped MnO2 nanorods were successfully synthesized and applied to Cs+ adsorption, showing high selectivity and adsorption capacity, especially in neutral media. The high adsorption ability of H-Ni-MnO2 NRs can be attributed to their special morphology, Ni doping, and Mn(III) amount enhancement induced by electrochemical reduction.

Summary: The study demonstrates that short-range ordering is the key factor driving activity independently of the initial oxidation state and composition of the calcined iridium oxides.

Summary: In this study, the phase evolution and reactions of vanadium hexacyanoferrate (VHCF) cathode in aqueous Zn-ion battery were investigated. The results revealed that VHCF electrode was gradually converted into zinc hexacyanoferrate and vanadium oxides (VOx) through multiple charge-discharge cycles. The redox behavior of VOx enhanced the specific capacity of the electrode. In addition, the presence of decavanadate anion, the intermediate of VHCF transformation, during electrochemical reaction was confirmed.

Summary: The electrochemical interface of Cu-3(HHTP)(2) with an organic electrolyte was investigated using simulations and experimental measurements. The excess charges mainly formed on the organic ligand, and cation-dominated charging mechanisms led to greater capacitance. By changing the ligand, the spatially confined electric double-layer structure and self-diffusion coefficients of in-pore electrolytes were improved. The performance of MOF-based supercapacitors can be controlled by modifying the ligating group.

Summary: This study investigates the impact of intermittent overcharging on battery performance and the underlying causes. The results show that intermittent overcharging accelerates capacity degradation and impedance rise in cells, leading to the loss of cathode active material and lithium inventory. Moreover, gas production resulting from side reactions causes sudden battery failure.

Summary: The same morphology CuS, Cu7S4, Cu9S5, Cu7.2S4, and Cu2S were successfully synthesized by the hydrothermal method. The galvanostatic charge-discharge (GCD) curves were calculated to be 43.29 (CuS), 86.3 (Cu7S4), 154 (Cu9S5), 185.4 (Cu7.2S4), and 206.9 F/g (Cu2S) at the current density of 1 A/g. The energy storage capacity of copper sulfide with the same morphology increased with the increase of the copper sulfide stoichiometric coefficient. In the second part of the work, agglomerated cuprous sulfide, microporous cuprous sulfide, and nano cuprous sulfide were successfully prepared, with the agglomerated structure showing the highest specific capacity.

Summary: The effect of Li2S deposition on the impedance response of Li-S battery cells was investigated. It was found that Li2S deposit has little effect on the impedance response, mainly due to its porous structure. Additionally, the deposition process of Li2S leads to a decrease in polysulfide species concentration in the electrolyte, resulting in a decrease in chemical capacitance.

Summary: Conventional monitoring of Li-ion battery cell performance is done through a combination of empirical measurement and modeling algorithms. This study presents a new approach using built-in electrochemical sensors to detect dissolved manganese ions in the battery cell. The sensors, printed on the separator, remain stable and have a negligible impact on the cell energy density. This universal approach can also be extended to detect other degradation products in the electrolyte.

Summary: Ca metal anode rechargeable batteries are considered a sustainable alternative to Li-ion batteries due to the low redox potential of Ca. A new calcium aluminate electrolyte is synthesized and compared with the boron analogue, showing improved conductivity, efficiency, stability, and battery performance. The higher oxidative stability of 0.5 V paves the way for high-voltage Ca batteries. Solvent quality and decomposition issues are identified, but the new aluminate salt opens up new possibilities for future Ca battery research.

Summary: We report a rationally designed triquinoxalinediol (TQD) organic cathode material for aqueous zinc-ion batteries, which exhibits high theoretical and practical capacities. The charge storage mechanism of TQD in aqueous zinc-ion batteries involves a co-insertion mechanism of protons and zinc cations. However, TQD suffers from capacity fading due to the dissolution of active material in the electrolyte.

Summary: This study presents an approach to improve the electrochemical performance of anthraquinone-based covalent organic framework (COF) cathode material in metal anode (Li, Mg) batteries through proper selection of the electrolyte and binder. The results show that the combination of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) in tetraethylene glycol dimethyl ether (TEGDME) as electrolyte and poly(tetrafluoroethylene) (PTFE) as binder led to the best electrochemical performance. The study also explores the performance of COF in magnesium cells using two different Mg electrolytes, pointing towards hindered transport.

Summary: Infiltration of sulfur into microporous carbon enables the use of carbonate-based electrolytes, forming a compact cathode electrolyte interface. The mechanism of sulfur conversion changes to a quasi-solid-state mechanism, resulting in a single sloping plateau of sulfur conversion. The narrow size of pores determines the sulfur maximum ratio within the carbon-sulfur composite. The confinement of sulfur in narrow pores affects its conversion into Li2S2/Li2S due to volumetric changes.
