Quasi-Solid-State Na-O Battery with Composite Polymer Electrolyte.

Na-O batteries have emerged as promising candidates due to their high theoretical energy density (1,601 Wh kg), the potential for high energy storage efficiency, and the abundance of sodium in the earth's crust. Considering the safety issue, quasi-solid-state composite polymer electrolytes are among the promising solid-state electrolyte candidates. Their higher mechanical toughness provides superior resistance to dendritic penetration compared with traditional liquid electrolytes.

Engineering Cathode-Electrolyte Interface of High-Voltage Spinel LiNiMnO via Halide Solid-State Electrolyte Coating.

The high-voltage spinel LiNiMnO (LNMO) cathode material with high energy density, low cost, and excellent rate capability has grabbed the attention of the field. However, a high-voltage platform at 4.7 V causes severe oxidative side reactions when in contact with the organic electrolyte, leading to poor electrochemical performance.

Highly Efficient Hydrogen Evolution from Seawater by Biofunctionalized Exfoliated MoS Quantum Dot Aerogel Electrocatalysts That Is Superior to Pt.

As a source of clean and sustainable energy, reliable hydrogen production requires highly efficient and stable electrocatalysts. In recent years, molybdenum disulfide (MoS) has been demonstrated as a promising electrocatalyst for hydrogen evolution reactions (HERs). Here, we demonstrate that a three-dimensional (3D) MoS quantum dot (MoSQD) aerogel is an efficient cathode electrocatalyst that can be used to enhance the HER in acid, neutral, and alkaline (e.
