“…[5][6][7] Compared with inorganic electrode materials, OEMs are gifted with wide sources of raw materials, outstanding theoretical specific capacity, mild synthesis conditions, designable structure and eco-friendly leading them to be one of the ideal electrode materials. [8][9][10][11][12][13] Although OEMs have many exciting advantages, their collocation with traditional organic liquid electrolytes (OLEs) did not get satisfactory results as we expected. The reason for this phenomenon is that OEMs are easily soluble in OLEs, causing the degradation of the capacity in organic secondary batteries (OSBs).…”

Organic electrode materials (OEMs) have attracted intensive attention owing to their high energy density, diverse structures and environmental friendliness. Unfortunately, the easy dissolution of OEMs in the organic liquid electrolytes (OLEs) severely damages the cycle stability of batteries. There is a hidden danger of catching fire due to a lot of heat generated from overcharge of the batteries. Moreover, OLEs are liable to leak and unstable at high voltage. Using solid-state electrolytes (SSEs) could effectively alleviate the above-mentioned problems at some extent. However, SSEs still show some weaknesses, including the large impedance of electrolyte-electrode interface (EEI) and low ion conductivity. In this review, the latest progress in the research of SSEs used in organic secondary batteries (OSBs) are summarized, with particularly focus on the ionic conductivity of SSEs, the combination of organic electrodes/ solid-state electrolytes, the optimization of EEI and the batteries cycle stability. Future directions for the development of OSBs are given from viewpoints of solid batteries.

“…The majority of commercial electrode materials are transition metal oxides, which are nonrenewable and damaging to the environment and do not meet the current concept of sustainable development. 1 The use of renewable and green organic compounds as electrode materials has been a hot topic in recent years. Organic molecules have the following advantages: high theoretical capacity, multiple active sites, structural tunability, and environmental friendliness.…”

Organic electrode materials are progressively becoming a research hotspot for energy storage materials due to their renewable and environmentally friendly features. Inspired by the energy transduction mechanism of flavin adenine dinucleotide (FAD) on the inner mitochondrial membrane of living organisms, the lithium storage electrochemical behavior of riboflavin (RF, vitamin B2) in lithium-ion batteries (LIBs) has been explored. The students are encouraged to find inspiration from organisms to design energy storage materials. This course is used to teach the principles of energy storage devices and the electrochemical mechanism of organic small molecules for upper-division undergraduates. This novel theory and experiment module is suitable for students with a foundation of computational chemistry, physical chemistry, and modern testing technology. The redox reaction mechanism of RF with multiple active sites is clarified through density functional theory (DFT) calculations. The LIBs assembled by the students are evaluated by using a battery testing system with electrochemical methods. The relative potentials calculated by DFT for the stepwise lithiation reactions are consistent with the reduction peak potential of the cyclic voltammetry and the plateau potential of the discharge curve, which demonstrates the rationality of the proposed electrochemical reaction mechanism. These findings confirm the expectation of using bioinspired redox-active moieties for LIBs and the development of organic electrode materials. The course can increase students’ interest in the field of organic active materials and renewable energy.

“…However, the dissolution of PTO in common organic electrolyte causes a rapid decrease in capacity. 23 In order to suppress dissolution in electrolytes, many strategies were applied, including PTO immobilization in (porous) carbons, 7,24 electrolyte optimization, 25 changing polarity with introducing -CO 2 Li or -NO 2 groups (salt modifications), 26,27 and polymerization of PTO. 28−33 Modified PTO structures were employed in the designed cathode materials as the main chain, 30,34 side group, 28 or covalent organic framework (COF)/covalent organic polymer(COP).…”

“…In particular, pyrene-4,5,9,10-tetraone (PTO) has been widely used among the organic-carbonyl-based cathode active materials in recent battery studies. ,, PTO has four carbonyl groups as electrochemical active sites, resulting in high theoretical specific capacity (409 mAh·g –1 ) and high redox capacity. However, the dissolution of PTO in common organic electrolyte causes a rapid decrease in capacity . In order to suppress dissolution in electrolytes, many strategies were applied, including PTO immobilization in (porous) carbons, , electrolyte optimization, changing polarity with introducing -CO 2 Li or -NO 2 groups (salt modifications), , and polymerization of PTO. − Modified PTO structures were employed in the designed cathode materials as the main chain, , side group, or covalent organic framework (COF)/covalent organic polymer(COP). ,, Although one of the most used techniques to cope with the dissolution problem is the polymer formation, to the best of our knowledge only one study was reported in which polymethacrylate as a linear organic polymeric chain bearing PTO units was synthesized that exhibited the remarkable charge–discharge properties as a Li-ion cathode material .…”

A cathode material based on polyphosphazene with pyrene-4,5,9,10-tetraone (PTO) units as electroactive groups with a high specific capacity in the side chain, poly[(bis(2-amino-4,5,9,10-pyrenetetraone)]phosphazene (PPAPT), is synthesized. The structural characterization of PPAPT is carried out by using appropriate standard spectroscopic methods such as 31P NMR spectroscopy, FT-IR, DSC, and TGA. The material is found to be an insoluble and halogen-free flame retardant in accordance with the results of the simple flame test and solubility control in electrolyte solutions accompanied by UV–vis analysis. The electrochemical performance of PPAPT is evaluated as a Li–ion battery cathode material. The fabricated cells demonstrate immensely good capacity retention with 72% after 500 discharge–charge cycles at a high current density of 20 C. In comparison with the pristine PTO, introducing a PTO unit into the side chain of the polyphosphazene leads to substantially improved performance because of the lowered LUMO energy levels of PPAPT. In order to investigate the reversibility of carbonyl groups as an electroactive side with respect to their chemical composition, complementary chemical post-mortem analyses are performed by FT-IR, X-ray photoelectron spectroscopy (XPS) analysis. Density functional theory (DFT) calculations are also proposed to determine HOMO–LUMO levels and investigate the lithiation mechanism of PPAPT.
