Enhancing the mobility of lithium-ions (Li+) through surface engineering is one of major challenges facing fast-charging lithium-ion batteries (LIBs). In case of demanding charging conditions, the use of a conventional artificial graphite (AG) anode leads to an increase in operating temperature and the formation of lithium dendrites on the anode surface. In this study, a biphasic zeolitic imidazolate framework (ZIF)-AG anode, designed strategically and coated with a mesoporous material, is verif...

Utilizing carbon materials as 3D lithium (Li) hosts hold a significant interest in constructing high-energy batteries. However, there are ongoing challenges associated with these frameworks owing to their poor Li affinity. Recent advancements, including alloying reactions with precious metals like silver (Ag) and gold (Au), have emerged as a promising technique to enhance the electrochemical performance of these host materials. Nevertheless, the search for cost-effective alternatives remains a p...

While porous carbon is widely used as a metallic lithium host framework, the weak wettability of the carbon hinders its usage. For this purpose, herein, we functionalized the porous carbon with oxidized nitrogen groups by utilizing nitric acid. We found that the functionalized porous carbon demonstrated an enhanced wettability compared to its non-functionalized counterpart. Moreover, by functionalizing the carbon surface with oxidized nitrogen during lithium plating and stripping, catalyzed lith...

Batteries are a promising technology in the field of electrical energy storage and have made tremendous strides in recent few decades. In particular, lithium-ion batteries are leading the smart device era as an essential component of portable electronic devices. From the materials aspect, new and creative solutions are required to resolve the current technical issues on advanced lithium (Li) batteries and improve their safety. Metal-organic frameworks (MOFs) are considered as tempting candidates...

Room-temperature sodium-sulfur (RT Na-S) batteries are considered to be a competitive electrochemical energy storage system, due to their advantages in abundant natural reserves, inexpensive materials, and superb theoretical energy density. Nevertheless, RT Na-S batteries suffer from a series of critical challenges, especially on the S cathode side, including the insulating nature of S and its discharge products, volumetric fluctuation of S species during the (de)sodiation process, shuttle effec...

Lithium (Li) metal is an ideal anode for high energy-density batteries. During Li plating and stripping, however, dendritic Li growth keeps generating an abundance of irreversible or inactive Li, resulting in severe performance degradation, short-circuiting, and eventually cell failure. Even if various porous frameworks have received considerable attention to directly store Li metals, achievable reversible and rate capabilities of porous hosts were still hindered by their morphological limitatio...
