“…3a, E,c dependence of Li 3 V 2 (PO 4 ) 3 electrode is presented as obtained in three different modes: by said modified measurement procedure (curve 1), in which every measurement of the electrode potential was preceded by cell exposure in the Bopen circuit^conditions for 24 h; by the standard PITT procedure with stepwise change of potential and exposure to zero current in each stage (curves 2 and 3); and galvanostatic charge-discharge curves (4.5). Delithiation processes of Li 3 V 2 (PO 4 ) 3 electrode to form the final phase V 2 (PO 4 ) 3 and reverse lithiation have been investigated by several authors [80][81][82][83][84]. They go through the following sequence of transformations:…”

In order to establish the mechanism and to determine the parameters of lithium transport in electrodes based on lithium-vanadium phosphate (Li 3 V 2 (PO 4 ) 3 ), the kinetic model was designed and experimentally tested for joint analysis of electrochemical impedance (EIS), cyclic voltammetry ( C V ) , p u l s e c h r o n o a m p e r o m e t r y ( P I T T ) , a n d chronopotentiometry (GITT) data. It comprises the stages of sequential lithium-ion transfer in the surface layer and the bulk of electrode material's particles, including accumulation of lithium in the bulk. Transfer processes at both sites are of diffusion nature and differ significantly, both by temporal (characteristic time, τ) and kinetic (diffusion coefficient, D) constants. PITT data analysis provided the following D values for the predominantly lithiated and delithiated forms of the intercalation material: 10 −9 and 3 × 10 −10 cm 2 s −1 , respectively, for transfer in the bulk and 10 −12 cm 2 s −1 for transfer in the thin surface layer of material's particles. D values extracted from GITT data are in consistency with those obtained from PITT: 3.5-5.8 × 10 −10 and 0.9-5 × 10 −10 cm 2 s −1 (for the current and currentless mode, respectively). The D values obtained from EIS data were 5.5 × 10 −10 cm 2 s −1 for lithiated (at a potential of 3.5 V) and 2.3 × 10 −9 cm 2 s −1 for delithiated (at a potential 4.1 V) forms. CV evaluation gave close results: 3 × 10 −11 cm 2 s −1 for anodic and 3.4 × 10 −11 cm 2 s −1 for cathodic processes, respectively. The use of complex experimental measurement procedure for combined application of the EIS, PITT, and GITT methods allowed to obtain thermodynamic E,c dependence of Li 3 V 2 (PO 4 ) 3 electrode, which is not affected by polarization and heterogeneity of lithium concentration in the intercalate.

Graphene oxide has a great potential as a suitable material for anodic sodium ion battery (NIBs) due to its unique behavior. The calculated reversible of lithium ion capacity of GO/ Li & Na / GO based anodic materials are widely improved comparing to the conventional graphite-based anodic materials. By this investigation GO sheets have been localized into the graphene as an item for enhancing electrochemical & Physical ratio. Moreover, the structure of GO/Li& Na/GO can be used for improving the capacities and electronics transport in the GO sheets-based NIBs. Therefore, these modifications of GO sheet and designing of GO/Li & Na/GO structures provide a strategy for increasing the performance of GO-based anode. GO/Li & Na/GO could also be accomplished into the free-standing anodes without any of binders or current's collectors, which will leads to increased energies densities of overall battery's designing.

Sodium-ion battery is a type of re-chargeable battery which uses sodium-ions as its charge carriers and is very similar to LIBTs in many ways. The measured reversible Sodium ion capacities of GO/Li&Na/GO based anodic materials are considerably improved compared to the conventional graphite-based anodic materials. Graphene oxide has displayed great behavior as suitable materials for anodic sodium ion batteries (LIBs) due to their unique properties. In this study GO sheet has been localized inside the graphene as an option to enhance electrochemical ratio. Moreover, the structure of GO/Li&Na/GO can be to improve the capacities and electrical transport in GO sheets-based LIBs. Therefore, the modification of GO sheet and design of GO/Li&Na/GO structure provide strategies for improving the performance of GO-based anodes. GO/Li&Na/GO could also be assembled into freestanding electrodes without any binder or current collector, which will lead to increased energies density for overall batteries designing. In addition, the relationship among electrical and ionic conduction for three cathode materials including LiCoO 2 , LiMn 2 O 4 , LiFePO 4 have been discussed towards phase changing in sodium anodes and how it relates to diffusivity and conductivity and the key conduction issues with some organic liquid and ionic liquid electrolytes.
