“…Considering that the average discharge voltage is about 1.7 V ( Figure 5b), the energy density of C 6 O 6 is estimated to be about 1533 Wh kg À1 C 6 O 6 , which is higher than that of commercial transition-metaloxide cathode materials and other reported organic cathode materials. [18] Furthermore,wetested the rate performance of C 6 O 6 ( Figure 5c). Thed ischarge capacities at higher current densities of 50, 100, 200, and 500 mA g À1 could maintain at 656, 560, 484, and 382 mA hg À1 ,r espectively (the capacity contributions from conductive Ketjen black have been subtracted).…”

Organic carbonyl compounds show potential as cathode materials for lithium-ion batteries (LIBs) but the limited capacities (< 600 mA hg À1 )a nd high solubility in electrolyte restrict their further applications.H erein we report the synthesis and application of cyclohexanehexone (C 6 O 6 ), which exhibits an ultrahigh capacity of 902 mA hg À1 with an average voltage of 1.7 Vat2 0mAg À1 in LIBs (corresponding to ah igh energy density of 1533 Wh kg À1 C 6 O 6 ). Ap reliminary cycling test shows that C 6 O 6 displays ac apacity retention of 82 %a fter 100 cycles at 50 mA g À1 because of the limited solubility in high-polarity ionic liquid electrolyte.Furthermore, the combination of DFT calculations and experimental techniques,such as Raman and IR spectroscopy, demonstrates the electrochemical active C=Og roups during dischargea nd charge processes.

“…This morphological integrity could give rise to the formation of the cathode SEI layer at only cathode surface, leading to long‐term cycling stability. To date, there have been a variety of the review articles which addressed the complex material and interfacial chemistry . Along with the previously published review articles, this review will be of particular interest to the battery researchers who are interested in the interfacial chemistry of the nickel‐rich cathode materials.…”

With increasing demands for high energy lithium‐ion batteries, layered nickel‐rich cathode materials have been considered as the most promising candidate due to their high reversible capacity and low cost. Although some of the materials with nickel contents ≦60 % were commercialized, there are tremendous obstacles for further improvement of electrochemical performance, which is strongly related to the unstable cathode surface and interfacial properties. In this regard, a specific review on the interfacial chemistry between the cathode and electrolyte during electrochemical testing is provided. We highlight the underpinning interfacial chemistry and degradation mechanisms of the cathode materials. Finally, light is shed on the recent efforts for enhancing the interfacial stability of the nickel‐rich cathode materials.

“…In order to overcome these problems, fabricating nanostructured anodic materials with high specific surface areas and stable structures, and designing composite anodic materials through introducing the carbonaceous substances and other conductive components into the active species have been demonstrated to be effective. [23] The cellulose derived anodic materials, especially various metal oxide based ones, offer porous network structures as the buffering matrices to relieve the volume changes of the electrodes, leading to better cycling stabilities.…”

Bio‐inspired synthetic method provides an effective shortcut to fabricate functional nanostructured materials with specific morphologies and designed functionalities. Natural cellulose substances (e. g., commercial laboratory cellulose filter paper) possesses unique three‐dimensionally cross‐linked porous structures and abundant functional groups for the functional modification on the surfaces. The deposition of metal oxide gel film on the surfaces of the cellulose nanofibers is facilely to be achieved through the surface sol‐gel process, resulting in metal oxide replicas of the initial cellulose substance or metal‐oxide/carbon nanocomposites. Moreover, the as‐deposited metal oxide gel films coated on the cellulose fiber surfaces provide ideal platforms for the further formation of specific functional assemblies, and eventually to the corresponding nanocomposite materials. Based on this methodology, various nanostructured composites were prepared and employed as anodic materials for lithium‐ion batteries, including metal‐oxides‐based (such as SnO2, TiO2, MoO3, FexOy, and SiO2) and Si‐based composites, as summarized in this personal account. Benefiting from the unique hierarchically porous network structures and the synergistic effects among the composite components of the anodic materials, the transfer of electrons/ions is accelerated and the structural stability of the electrode is enhanced, leading to the improved lithium storage performances and promoted cycling stability.
