Prussian Blue Analogue-Templated Nanocomposites for Alkali-Ion Batteries: Progress and Perspective.

Lithium-ion batteries (LIBs) have dominated the portable electronic and electrochemical energy markets since their commercialisation, whose high cost and lithium scarcity have prompted the development of other alkali-ion batteries (AIBs) including sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs). Owing to larger ion sizes of Na and K compared with Li, nanocomposites with excellent crystallinity orientation and well-developed porosity show unprecedented potential for advanced lithium/sodium/potassium storage. With enticing open rigid framework structures, Prussian blue analogues (PBAs) remain promising self-sacrificial templates for the preparation of various nanocomposites, whose appeal originates from the well-retained porous structures and exceptional electrochemical activities after thermal decomposition.

Metal-Organic Framework-Based Materials for Advanced Sodium Storage: Development and Anticipation.

As a pioneering battery technology, even though sodium-ion batteries (SIBs) are safe, non-flammable, and capable of exhibiting better temperature endurance performance than lithium-ion batteries (LIBs), because of lower energy density and larger ionic size, they are not amicable for large-scale applications. Generally, the electrochemical storage performance of a secondary battery can be improved by monitoring the composition and morphology of electrode materials. Because more is the intricacy of a nanostructured composite electrode material, more electrochemical storage applications would be expected.

Method for Synthesis of Zeolitic Imidazolate Framework-Derived LiCoO/CNTs@AlF with Enhanced Lithium Storage Capacity.

Metal-organic framework-derived lithium cobaltate nanoparticles were fabricated by annealing of the ZIF-67 precursor with LiCO under air, followed by homogeneous AlF coating and carbon nanotubes (CNTs) wrapping. The as-prepared AlF-coated LiCoO/CNTs electrode can act as a potential cathode for enhanced lithium storage at both room temperature and an elevated temperature of 50 °C.

Four new Zn(ii) and Cd(ii) coordination polymers using two amide-like aromatic multi-carboxylate ligands: synthesis, structures and lithium-selenium batteries application.

Four new coordination polymers, {[Zn(3-PBI)(HO)]·2DMF} (1), [Cd(3-PBI)(DMF)] (2), {[Zn(μ-O)(4-PBI)]·3DMF} (3), {[Cd(4-PBI)(HO)]·13HO} (4), have been constructed from two isomeric flexible multi-carboxylate ligands, 3-HPBI = 5-(3-(pyridin-3-yl)benzamido)isophthalic acid and 4-HPBI = 5-(3-(pyridin-4-yl)benzamido)isophthalic acid. Structural analysis reveals that compound 1 is a one-dimensional (1D) ladder-like chain assembled by Zn(ii) ions and 3-PBI ligands, which further extend into a 3D supramolecular structure through π⋯π stacking and interlayer (O-H⋯O) hydrogen bonding interactions. In compound 2, Cd metal ions are connected by carboxylate groups to form [Cd(COO)] secondary building units (SBUs).
