Recent Progress in Organic Electrodes for Li and Na Rechargeable Batteries

Advanced Materials, 2018

Organic rechargeable batteries, which use organics as electrodes, are excellent candidates for next‐generation energy storage systems because they offer design flexibility due to the rich chemistry of organics while being eco‐friendly and potentially cost efficient. However, their widespread usage is limited by intrinsic problems such as poor electronic conductivity, easy dissolution into liquid electrolytes, and low volumetric energy density. New types of organic electrode materials with various redox centers or molecular structures have been developed over the past few decades. Moreover, research aimed at enhancing electrochemical properties via chemical tuning has been at the forefront of organic rechargeable batteries research in recent years, leading to significant progress in their performance. Here, an overview of the current developments of organic rechargeable batteries is presented, with a brief history of research in this field. Various strategies for improving organic el...

Recent Progress in Advanced Organic Electrode Materials for Sodium‐Ion Batteries: Synthesis, Mechanisms, Challenges and Perspectives

Advanced Functional Materials, 2020

Rechargeable sodium‐ion batteries (SIBs) are considered attractive alternatives to lithium‐ion batteries for next‐generation sustainable and large‐scale electrochemical energy storage. Organic sodium‐ion batteries (OSIBs) using environmentally benign organic materials as electrodes, which demonstrate high energy/power density and good structural designability, have recently attracted great attention. Nevertheless, the practical applications and popularization of OSIBs are generally restricted by the intrinsic disadvantages related to organic electrodes, such as their low conductivity, poor stability, and high solubility in electrolytes. Here, the latest research progress with regard to electrode materials of OSIBs, ranging from small molecules to organic polymers, is systematically reviewed, with the main focus on the molecular structure design/modification, the electrochemical behavior, and the corresponding charge‐storage mechanism. Particularly, the challenges faced by OSIBs and ...

Electroactive organics as promising anode materials for rechargeable lithium ion and sodium ion batteries

Energy Materials, 2022

Electroactive organics have attracted significant attention as electrode materials for next-generation rechargeable batteries because of their structural diversity, molecular adjustability, abundance, flexibility, environmental friendliness and low cost. To date, a large number of organic materials have been applied in a variety of energy storage devices. However, the inherent problems of organic materials, such as their dissolution in electrolytes and low electronic conductivity, have restricted the development of organic electrodes. In order to solve these problems, many groups have carried out research and remarkable progress has been made. Nevertheless, most reviews of organic electrodes have focused on the positive electrode rather than the negative electrode. This review first provides an overview of the recent work on organic anodes for Li- and Na-ion batteries. Six categories of organic anodes are summarized and discussed. Many of the key factors that influence the electrochemical performance of organic anodes are highlighted and their prospects and remaining challenges are evaluated.

Recent Progress on Organic Electrodes Materials for Rechargeable Batteries and Supercapacitors

Materials

Rechargeable batteries are essential elements for many applications, ranging from portable use up to electric vehicles. Among them, lithium-ion batteries have taken an increasing importance in the day life. However, they suffer of several limitations: safety concerns and risks of thermal runaway, cost, and high carbon footprint, starting with the extraction of the transition metals in ores with low metal content. These limitations were the motivation for an intensive research to replace the inorganic electrodes by organic electrodes. Subsequently, the disadvantages that are mentioned above are overcome, but are replaced by new ones, including the solubility of the organic molecules in the electrolytes and lower operational voltage. However, recent progress has been made. The lower voltage, even though it is partly compensated by a larger capacity density, may preclude the use of organic electrodes for electric vehicles, but the very long cycling lives and the fast kinetics reached r...

Electroactive Organic Molecules Immobilized onto Solid Nanoparticles as a Cathode Material for Lithium-Ion Batteries

Angewandte Chemie-international Edition, 2010

Li-ion batteries are considered very promising energy-storage devices for a variety of applications including large-scale batteries. Given the large quantities of energy to be stored in such applications, the amount of cathode materials will be in the order kilograms per battery unit. This will not only raise concerns about the finite quantity of some resources on the earth and its environmental intolerance but also about overall CO 2 management. To overcome such problems efficiently, Armand, Chen, and co-workers recently suggested a new class of sustainable lithium batteries based on organic compounds. The other available literature mainly reports on the use of polymers as possible electroactive materials in Liion batteries or totally organic polymer based rechargeable batteries. Indeed, certain redox active centers of organic molecules (and also polymers) offer almost unlimited combinations of atomic arrangements and many possibilities for substitutions; this allows for fine tuning of the desired properties. Herein, our primary focus is the use of "monomer" organic molecules as an active material for Li-ion batteries. The reversible capacity of certain organic compounds, such as Li x C 6 O 6 , can reach values as high as 580 mA h g À1 , but their operating voltage is typically quite low (about 2 V vs. Li). However, the most critical problem associated with utilization of organic materials in batteries is the high solubility of many interesting organic molecules in the aprotic electrolytes commonly used in the Li-ion batteries. Although soluble molecules can act as a charge carrier, the operation of a battery using such molecules is diffusionlimited. Besides that, the use of soluble organic molecules in a long-term cycling process may be questionable. Herein we propose, for the first time, that this problem can be overcome by grafting (anchoring) of soluble electroactive organic molecules onto the surface of an appropriate insoluble substrate. The essence of this approach is the strong attach-
