Organic batteries for a greener rechargeable world

Reversible Metal and Ligand Redox Chemistry in Two-Dimensional Iron–Organic Framework for Sustainable Lithium-Ion Batteries

“…Rechargeable lithium-ion batteries (LIBs) have flourished as one of the prominent electrochemical energy storage technologies over the past decades and dominated in various fields, such as mobile electronic devices and smart grids. 1 Compared with the conventional Co-or Ni-based electrode chemistry, organic electrode materials are emerging as a promising sustainable alternative for large-scale electric energy storage, benefitted from their earth-abundant element compositions, environmental friendliness, and renewability. 2 Organic molecules with electroactive functional groups, encompassing conjugated carbonyl, imine, organosulfur, and azo compounds, have been widely explored for reversible lithium storage.…”

In situ synthesis of Cu(ii) dicarboxylate metal organic frameworks (MOFs) and their application as battery materials

“…3,4 Suitable task-to-battery matching is an important consideration as it helps alleviate some of the technological shortcomings. 5 For example, batteries that have low energy density, but are inexpensive to manufacture, can find suitable use as large, stationary energy storage systems. Consequently, development of new battery materials designed for specific purposes is paramount to future development of battery-based energy storage.…”

Metal-organic frameworks for fast electrochemical energy storage: Mechanisms and opportunities

“…The coordination geometry between metal node and ligand define the MOF's network topology and potential porosity. 13,14 The chemical identity of the nodes and ligands, along with MOF topology, play a deterministic role in the ultimate functionality of the material. Many MOFs possess accessible porosity and high specific surface areas; 15 consequently, their applications in gas storage, 16 fluid separations, 17 and catalysis 18 have been extensively studied.…”

“…22 An emerging class of electrically conductive MOFs shows a marked improvement in performance over their non-conductive counter parts and demonstrates substantial promise for high-rate energy storage. 14,23 Along with electrical conductivity, density and accessibility of the redox active sites and MOF stability under operating conditions are equally critical to consider at the design stage.…”
