Anisotropic Li⁺ ion conductivity in a large single crystal of a Co(iii) coordination complex

Abstract

Anisotropic Li+ ion conductivity has been observed in a large single crystal of a novel Co(iii) coordination complex attributable to the presence of directional ion channels with a suitable size.

Recent progress in metal–organic polymers as promising electrodes for lithium/sodium rechargeable batteries

“…148,150,[152][153] Motivated by the doping strategy that has been widespread in ameliorating conventional Li-rich layered oxides (Ni, Co, Mn) and Ti-based anode materials, bimetallic MOPs are investigated to ameliorate the coordination conditions and present better electrochemical performance than monometallic system. [154][155][156][157][158] One possible way to generate isostructural bimetallic MOPs is to utilize two metal ions with comparable ionic radii such as Zn (II, 0.74 Å) and Co (II, 0.72 Å). Isostructural CoZn-ZIF is prepared by 64% Co 2+ substitution of Zn 2+ in Zn-ZIF-8 crystal.…”

Lithium-, Sodium-, and Potassium-ion Conduction in Polymeric and Discrete Coordination Systems

“…On the other hand, discrete coordination systems commonly showed relatively low conductivities on the order of 10 ¹6 S cm ¹1 at room temperature, even in the presence of water molecules. 56,57 2.2 Incorporation of Li + Salt into MOFs. The bulk conduction of Li + ions in the solid state in coordination compounds as the matrix was first shown by Long and coworkers in 2011.…”

“…1315,9599 To date, only two compounds have been investigated. 56,57 The main reason arises from their high solubility in a solvent for this class of compounds.…”

MOF-Derived FeS/C Nanosheets for High Performance Lithium Ion Batteries

“…Up to now, MOFs have been widely explored in various applications including catalysis, drug delivery, optoelectronics, and electrochemical fields, etc. [29,30,31,32,33,34] due to the superiority of controllable structures, huge surface area, tunable pore size, and high porosity. It is generally accepted that MOFs are not suitable for the electrochemical application as electrodes because of their poor electronic conductivity.…”
