Perspectives in Lithium Batteries

Pairing Cross‐Linked Polyviologen with Aromatic Amine Host Structure for Anion Shuttle Rechargeable Batteries

“…Along that line, the implementation of organic electroactive materials (OEMs) could be perceived as one of the possible alternatives since switching from metal‐based compounds to organic structures can offer several potential environmental assets including (i) the possibility to alleviate the pressure on scarce metals currently used by the global battery industry and (ii) the potential synthesis of electrode materials from renewable resources as underlined by our group more than ten years ago . In addition, organic compounds offer high structural designability through the well‐established principles of organic chemistry and notably access to both n‐ and p‐type electrochemical storage mechanisms (“n‐type” electrode reactions involve an ionic compensation with cation release upon oxidation (like Li + ) whereas “p‐type” electrode reactions imply an anion uptake (like BF 4 − )) making various cell or electrode configurations possible (i.e., cationic or anionic rocking‐chair cell, and dual‐ion cell) . As recalled by Yao et al.…”

Chameleonic Behavior of the α‐Methylcyclopropyl Group and Its Through‐Space Interactions: A Route to Stabilized Three Redox States in Diarylnitroxides

“…The poor ecologic situation dictates the necessity for the gradual replacement of inorganic metal‐containing compounds for biodegradable and recyclable raw materials, highlighting the elaboration of new competitive redox‐active organic molecules as the main components for electrochemical energy storage and conversion systems . One of the topical areas is the development of ambipolar redox active materials for all‐organic “poleless” batteries, which are preferable for technological and economical reasons .…”

An Aqueous Conducting Redox‐Polymer‐Based Proton Battery that Can Withstand Rapid Constant‐Voltage Charging and Sub‐Zero Temperatures

“…Batteries consisting of one organic and one inorganic electrode have been extensively studied with the aim of maximizing cell potential and investigating the characteristics of organic electrode materials . All‐organic batteries are rarer, but are gaining in popularity, as exemplified by the pioneering work of Nishide using organic radical batteries, and Poizot using lithiated tetrahydroxybenzoquinone . Recently, the work of Schubert's, Gaubicher's and Aziz's groups on all‐organic battery concepts has also shown promising results .…”
