Towards superior lithium–sulfur batteries with metal–organic frameworks and their derivatives

Selective Co(II) Adsorption Using Hollow ZIF-8 Nanostructures with Embedded Fe3O4 Nanoparticles

“…Metal–organic frameworks (MOFs) are highly ordered porous crystalline materials composed of coordinated units of organic linkers and metal or metal nodes . MOFs have made significant progress in various fields such as catalysis, sensing, gas separation, drug delivery, and water treatment due to their unique properties. − MOFs are also promising adsorbents due to their porous structure and adjustable size. However, pristine MOFs have limitations such as insufficient active centers and a high mass transfer resistance.…”

Towards the Enhanced Lithium‐Ion Batteries by Designing (N, Co, Zr, P) Tetra‐Doped Porous Carbon Anode

“…[16] In addition to non-metallic heteroatoms, metallic atoms are also viewed as the advanced doping gest to modify the carbon materials. [17][18] Previous works demonstrated that the electrical conductivity and overall electrochemical properties were effectively improved with metallic heteroatoms, [18][19] referring to the Table 1 which summarizes the specific capacity of metal atom doped carbon matrix as LIBs anodes. It was explored that the metal atoms acted as catalysts introducing a large number of lipophilic binding sites and regulating the kinetic behavior of Li + .…”

Interfacial engineering of Si anodes by confined doping of Co toward high initial coulombic efficiency

“…14 Otherwise, surface coating has been proposed as an effective method to suppress the volume expansion, mitigate particle crushing and prevent the direct contact of Si with the electrolyte. 15–19 For example, the Si/C-composite has been extensively studied, 20 as it effectively buffers the deformation of Si as well as increases the electrical conductivity. However, the dangling bonds of the amorphous carbon coating may result in irreversible trapping of Li, leading to low ICE.…”
