Graphene Paper

Graphene paper (GP) with layered structure and highly conductive network is fabricated by a facile technique of vacuum filtration and studied as a single-component and binder-free anode of lithium ion batteries (LIBs). The process of fabrication of GP without any binder and high-temperature treatment, in the meantime, great improvement in both the capacity and cycling performance of the GP electrodes have compared with other kinds of traditional graphite electrode materials. Given the simplifying anode fabrication, low manufacturing costs and many electrochemical properties of the GP anode, it is regarded as an excellent anode material of LIB with great promise for its both excellent cycling performance and electrochemical properties. The specific capacity can reach to over 200 mAhg-1after 60 charge-discharge cycles under the current rate of 50 mAg-1.

Fe2O3/Ga2O3 composite and GaFeO3 electrodes worked as rechargeable electrode materials for lithium-ion batteries, whereas their capacities were gradually decreased with increasing of cycle number. The initial Li insertion capacities (cut-off voltage: 0.01 V) were 1643 mAh/g for Fe2O3/Ga2O3 composite and 1196 mAh/g for GaFeO3, respectively. Despite same Fe/Ga atomic ratio, Fe2O3/Ga2O3 composite showed a higher capacity than that of GaFeO3 over the 50 cycles.

Abstract The morphology and nanosize of cathode materials play a crucial role in the improved electrochemical properties of the electrode material for lithium ion batteries. Herein, we report the synthesis of a novel NH4V3O8 rectangular nanotube via a facile one-pot solvothermal protocol with the use of the mixing solvent containing glycerol, ethanol, and ethylene glycol. The morphology and nanosize evolution of the as-prepared NH4V3O8 materials from the addition of different solvents has been systematically investigated. The electrochemical properties of these materials are closely related to their structure. Compared with other synthesized counterparts with three different morphologies (nanoparticle, ultra-small nanoparticle, and hierarchical microsheet), the resultant NH4V3O8 rectangular nanotube exhibited high reversible capacity with a maximum discharge capacity of 253.8 mAh g− 1at 15 mA g− 1, and the capacity retention rate is 75 % after 50 cycles. This work reveals the relationship between the morphology and electrochemical performance of NH4V3O8 and provides a feasible method for the synthesis of high-performance electrode materials.

The electrodes of lithium-ion batteries (LIBs) are multicomponent systems and their electrochemical properties are influenced by each component, therefore the composition of electrodes should be properly balanced. At the beginning of lithium-ion battery research, most attention was paid to the nature, size, and morphology peculiarities of inorganic active components as the main components which determine the functional properties of electrode materials. Over the past decade, considerable attention has been paid to development of new binders, as the binders have shown great effect on the electrochemical performance of electrodes in LIBs. The study of new conductive binders, in particular water-based binders with enhanced electronic and ionic conductivity, has become a trend in the development of new electrode materials, especially the conversion/alloying-type anodes. This mini-review provides a summary on the progress of current research of the effects of binders on the electrochemical properties of intercalation electrodes, with particular attention to the mechanisms of binder effects. The comparative analysis of effects of three different binders (PEDOT:PSS/CMC, CMC, and PVDF) for a number of oxide-based and phosphate-based positive and negative electrodes for lithium-ion batteries was performed based on literature and our own published research data. It reveals that the combined PEDOT:PSS/CMC binder can be considered as a versatile component of lithium-ion battery electrode materials (for both positive and negative electrodes), effective in the wide range of electrode potentials.
