Article Abstract
Li-O batteries (LOBs) possess the highest theoretical gravimetric energy density among all types of secondary batteries, but they are still far from practical applications. The poor rate performance resulting from the slow mass transfer is one of the primary obstacles in LOBs. To solve this issue, a rotating cathode with periodic changes in the electrolyte layer thickness is designed, decoupling the maximum transfer rate of Li and O. During rotation, the thinner electrolyte layer on the cathode facilitates the O transfer, and the thicker electrolyte layer enhances the Li transfer. As a result, the rotating cathode enables the LOBs to undergo 58 cycles at 2.5 mA cm and discharge stably even at a high current density of 7.5 mA cm. Besides, it also makes the batteries exhibit a large discharge capacity of 6.8 mAh cm, and the capacity decay is much slower with increasing current density. Notably, this rotating electrode holds great promise for utilization in other electrochemical cells involving gas-liquid-solid triple-phase interfaces, suggesting a viable approach to enhance the mass transfer in such systems.

Aqueous zinc-ion microbatteries exhibit promising prospects for wearable devices due to their high safety and cost-effectiveness but face challenges such as low energy density and short cycle life. To address these challenges, a dual-plating flexible Zn-Br microbattery was developed using freestanding MXene films as a zinc metal free anode. The MXene anode retains no redundant Zn, as Zn from the electrolyte undergoes deposition/stripping reactions on its substrate, thereby eliminating the necessity for excess zinc.

All-solid-state batteries (ASSBs), equipped with highly ion-conductive sulfide solid electrolytes and utilizing lithium plating/stripping as anode electrochemistry, suffer from 1) chemical vulnerability of the electrolytes with lithium and 2) physical growth of lithium to penetrate the electrolytes. By employing an ordered mesoporous graphitic carbon (OMGC) framework between a sulfide electrolyte layer and a copper current collector in ASSB, the concerns by are addressed 1) minimizing the chemically vulnerable interface (CVI) between electric conductor and solid electrolyte, and 2) allowing lithium ingrowth toward the porous structure via Coble creep, a diffusional deformation mechanism of lithium metal along the lithium-carbon interface. The void volume of the framework is fully filled with lithium metal, despite ionic pathways not being provided separately, even without additional lithiophiles, when an enough amount of lithium is allowed to be plated.

Bipolar membranes (BPMs) are increasingly recognized as a promising electrolyte option for water electrolysis, attributable to their distinctive properties derived from the membrane's layered structure, which consists of an anion exchange (AEL) and a cation exchange layer (CEL). This study investigates four different BPMs and the influence they have on the performance of a water electrolysis cell under two different feed configurations: (1) a symmetric deionized water feed to both anode and cathode compartments and (2) an asymmetric feed with a 0.5 mol/L NaCl catholyte feed and a deionized water anolyte feed.

Background: Cerebellar pathologies in adults can have a wide range of hereditary, acquired and sporadic-degenerative causes. Due to the frequency in daily hospital, especially intensive care, settings, electrolyte imbalances are an important, yet rare differential diagnosis. The hypomagnesemia-induced cerebellar syndrome (HiCS) constitutes a relevant disease entity with clinical and morphological variability due to a potential progression of symptoms and a promising causal treatment.

Li-metal batteries promise ultrahigh energy density, but their application is limited by Li-dendrite growth. Theoretically, fluorine-containing anions such as bis(fluorosulfonyl)imide (FSI) in electrolytes can be reduced to form LiF-rich solid-electrolyte interphases (SEIs) with high Young's modulus and ionic conductivity that can suppress dendrites. However, the anions migrate toward the cathode during the charging process, accompanied by a decrease in the concentration of interfacial anions near the anode surface.
