“…Wang et al prepared a composite of juglone and reduced graphene oxide (RGO) as electrodes, which exhibited a respectable electrochemical performance with a capacity of 305 mA h g −1 . [ 460 ] Di-sodiated 2, 5-dihydroxy-1, 4-benzoquinone (Na 2 DBQ), which is an analogue of the previously reported Li version, [ 466 ] was recently proposed as a promising anode for NIBs. [ 465 ] Na 2 DBQ displayed a capacity of 265 mA h g −1 at 0.1 C rate at approximately 1.2 V vs Na + /Na and a stable cycle life over 300 cycles at 1 C rate.…”

Grid‐scale energy storage systems (ESSs) that can connect to sustainable energy resources have received great attention in an effort to satisfy ever‐growing energy demands. Although recent advances in Li‐ion battery (LIB) technology have increased the energy density to a level applicable to grid‐scale ESSs, the high cost of Li and transition metals have led to a search for lower‐cost battery system alternatives. Based on the abundance and accessibility of Na and its similar electrochemistry to the well‐established LIB technology, Na‐ion batteries (NIBs) have attracted significant attention as an ideal candidate for grid‐scale ESSs. Since research on NIB chemistry resurged in 2010, various positive and negative electrode materials have been synthesized and evaluated for NIBs. Nonetheless, studies on NIB chemistry are still in their infancy compared with LIB technology, and further improvements are required in terms of energy, power density, and electrochemical stability for commercialization. Most recent progress on electrode materials for NIBs, including the discovery of new electrode materials and their Na storage mechanisms, is briefly reviewed. In addition, efforts to enhance the electrochemical properties of NIB electrode materials as well as the challenges and perspectives involving these materials are discussed.

“…However, they suffer from poor cycling and sluggish rate performance owing to their high solubility in traditional organic electrolyte and low conductivity [6,7]. Many attempts have been made to suppress the solubility such as polymerization [8][9][10][11][12], electrolyte optimization [13], anchoring on solid substrates [14] and formation of salts [15,16].…”

Enhanced adsorption of carbonyl molecules on graphene via π-Li-π interaction: a first-principle study

et al. 2017

Carbonyl compounds with elements of C, H, and O and reversible redox-active centers are promising electrode materials in rechargeable batteries owing to their high theoretical capacity, structure flexibility and resources abundance. However, the low conductivity and the dissolution of active molecules in organic electrolyte limit the practical application. Immobilizing the carbonyls on graphene provides a simple approach to address these two issues. However, most reported interaction between carbon-based substrates and carbonyl compounds is weak π-π interaction, which is not strong enough to prohibit the detachment of active materials from carbon surface, and thus leading to undesirable cycling performance. Herein, we applied the first principle calculations to study the carbonyls-graphene interaction and found that the weak π-π interaction can be rationally converted to the strong π-Li-π interaction via introducing the groups containing Li atoms. The introduced Li atoms can cooperatively bind with the two aromatic π components through the covalent Li-carbonyl compounds interaction and Li-graphene interaction. The concept of π-Li-π interaction provides a versatile method to suppress the dissolution of active materials and increase the electronic conductivity at the same time, which gains insight into the design of organic electrode materials for rechargeable batteries with high performance.

“…So far, it has been reported that several coordination polymers showed electrochemical activity for lithium-ion batteries. A Li-O bonds bridged coordination polymer Li 2 C 6 H 2 O 4 with carbonyl groups and 2-D layered aromatic rings showed bad cycling stability as cathode materials for lithium-ion batteries [15]. Manganese-based layered coordination polymer (Mn-(tfbdc)(4,4 0 -bpy)(H 2 O) 2 ) with microporous structure was synthesized by reaction of 2,3,5,6-tetrafluoroterephthalatic acid (H 2 tfbdc) and 4,4 0 -bipyridine (4,4 0 -bpy) with manganese (II) acetate tetrahydrate in water solution, delivering a low lithium storage capacity of 390 mA h g À1 due to high molecular weight and rigid organic framework for the presence of 4,4 0 -bipyridine linker [16].…”
