Abstract
Already electrically contacted metal oxide/carbon materials for supercapacitor electrodes are derived from electrodeposited cobalt– or manganese–organic films on current collectors.
Highlights
Electrodeposited films to metal–organic framework (MOF)-derived electrochemical energy storage electrodes: a concept of simplified additive-free electrode processing for self-standing, ready-to-use materials†
The thermal decomposition of metal–organic frameworks (MOFs) is a synthesis approach to obtain a wide range of functional porous metal oxide,[1,2,3] carbon,[4,5] hybrid or composite materials,6–10‡ exploiting the properties of the framework compounds which consist of homogenously and highly distributed metal ions and organic moieties
We demonstrate how electrochemically deposited metal–organic framework coatings are directly thermolysed on metal foils, which later serve as current collectors
Summary
Electrodeposited films to MOF-derived electrochemical energy storage electrodes: a concept of simplified additive-free electrode processing for self-standing, ready-to-use materials†. The isostructural manganese oxide spinel Mn3O4 is more environmentally compatible and has been investigated as active component for lithium battery anodes,[29,30,31] electrochemical capacitors[32,33] and electrocatalysis.[34] The poor electronic conductivity of Mn3O4 limits its performance. This issue was addressed by nanostructuring and combining the oxide with various carbon materials, achieving remarkable enhancements for the discussed applications.[35,36,37,38,39].
