pentoxide (V2O5) cathode was fabricated via a facile simple and microwave-assisted method by the utilization of Andrographis paniculata leaf extract as fuel and optimizes the electrochemical applications Structural and surface morphology of V2O5 nanoparticles was analyzed by various spectroscopic techniques like SEM and TEM The PXRD exhibits an orthorhombic crystal structure with an average crystallite size (32 nm) The band at 497 cm-1 is attributed to V-O-V stretching vibration through FTIR analysis The electrochemical characterization of synthesized V2O5 nanoparticles was studied towards the lithium-ion battery applications Various parameters like Charge-Discharge, Cyclic Voltammogram (CV) Columbic efficiency have performed The V2O5 exhibits a reversible capacity of 225mAhg-1 after 50 cycles The enhanced performance of the lithium-ion batteries is due to green synthesized V2O5 nanoparticles Keywords: Andrographis paniculata, microwave-assisted method, V2O5, Li-ion battery Introduction In general, electrical energy storage and portable electronic devices were made from Lithium-ion batteries (LIBs), which can offer the best energy to weight performance Lots of efforts were made to develop several anode, cathode and electrolyte materials, the huge response for LIBs is capable of producing high energy density along with good and stable cyclability continuously needs to synthesize high efficacy electrode materials At the same time, developing applications are directing the research for LIBs to a new trend, i.e successful enhancement of battery performances by nanostructured electrodes Primary versions of these nanomaterials are already in the marketplace, especially in the applications of portable power devices In recent times, lithium-ion batteries are also visible in blade electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) on automotive applications Surviving applications like portable electronics, where lithium-ion technology is entirely deep rooted for the implementation of nanomaterials electrodes to provide extraordinary performance at a preferred power level with constant cycle life The improvement of novel material with good battery performance is an important matter; capacity and retaining of active materials like metals, metal oxides, metal sulfides, and metal alloys are being considered Metal oxides are motivating among these materials, because of their related reactions and repetitive insertion conversion process, permitting the supply of greater capacity Hollow and porous structures of metal oxide semiconductors gained much attention because of their distinct structure dependent properties that enhance them in a wide range of applications like conversion and storage, catalysis and biomedicine [1-6] Anode and cathode of battery materials directly participate or indirectly help for catalytic action in an electrochemical conversion process Even promote to get enhanced properties to achieve high capacity, high columbic efficiency, and low toxicity, mainly to avoid unwanted additives Here we emphasized on powder form of metal oxides, which exhibits unique novel physical and chemical properties due to density, the surface to volume ratio and spatial confinement Specialized local and collective features are produced among the transition metal oxide for the diverse potential electrochemical devices to mitigate the energy crisis Among numerous electrode materials, V2O5 is an ensuring cathode material for energy storage systems, outstanding to its easy synthesis, abundance, and large theoretical capacity Vanadium pentoxide to act as cathode towards lithiation/de-lithiation among the currently available cathode materials LiCoO2, LiMn2O4, LiFePO4, and LiNi1-x-yCoxMnyO2, Moreover, vanadium pentoxide has special properties such as high coefficient of thermal resistance, abundant sources, better safety and well-studied intercalation compound due to its large surface area and easy transportation of charge [7] Various methods have been suggested for the synthesis of V2O5 namely hydrothermal, combustion, sol-gel, precipitation, electrodepositing, droplet emulsion, etc Table showed the comparison of present work with V2O5 reported work (synthesis method, morphology, and applications) In the present study reports the V2O5 nanoparticles by the microwave-assisted green method using Andrographis paniculata (chelating agent) It is a facile, simple, cost-free and less time-consuming combustion method to obtain the single phased of V2O5 NPs These structures lead to increase the diffusion co-efficient As a substitute of common fuels for carbon sources such as glycitric acid, urea, etc., Microwave-assisted green V2O5 nanoparticles are employed as anode material for lithium-ion battery Table Different application V2O5 nanoparticles using different methods Materials Synthesis method Morphology Applications Ref V2O5 Green route

of A paniculata were collected from surrounding of Bharathidasan University campus, were washed with DD water and heat to get extract as shown in the procedure reported by Karthik et al [15-16] V2O5 nanoparticles were prepared by the microwave-assisted biogenic method Stoichiometric amounts of Ammonium metavanadate were homogeneously stirred with 100 mL of A paniculata extract solution for about h at RT A domestic microwave oven (800 W, 2.45 GHz) was used for the synthesis The reaction mixture was placed inside the microwave oven and in the convection mode irradiated for 20 The obtained product was subjected to calcination at 500°C for h The XRD analysis was operated on Rikagu Mini Flexll Desktop, with Cu-Kα radiation (λ=1.5418 Å) at 40 KV, 25 mA The structural interpretation was recorded in the form FTIR spectrum in JASCO 460 PLUS FTIR spectrometer Surface morphologies of green synthesized V2O5 nanoparticles were investigated by SEM (VEGA TESCAN SEM) and TEM (JEOL-JEM 2100F) Electrochemical measurements done by fabrication of required electrodes as reported by Saji et al Active material V2O5 nanopowder (80 wt %), Carbon black (15%) and polyvinylidene fluoride binder (PVDF wt %) were vital for the construction of electrode Charge-discharge profile was examined between 0.01V and 3V vs lithiation and delithiation, by utilizing CHI 660D Austin USA, to the Biologic BCS-80 Battery testing unit [17] Results and Discussion 3.1 Structural Characterization by XRD and FTIR The resulting products (V2O5 NPs) prepared by microwave-assisted biogenic method was characterized by PXRD to identify the crystallite structure and the diffraction pattern presented in Fig.1 The XRD pattern corresponds to the orthorhombic phase of V2O5 and it is in good agreement with the peaks and also matches with JCPDS card no 41-1426 It consisted strong (0 1), (1 0), and (4 0) peaks at the diffracted angles 20.19, 26.18 and 31.04 respectively Which were signified the strong and narrow peaks of as prepared products i.e V2O5 NPs illustrate the high crystallinity and lattice parameters were a= 11.51, b= 3.65 and c= 4.38 Å [18] Also, there are no obvious impurity peaks can be noticed, representing the obtained V2O5 phase with high purity and the complete form of V2O5 during heat-treatment The average crystallite size of the V2O5 nanoparticles was found to be 32 nm according to Debye-Scherrer’s equation as reported earlier [19] D=kλ/β cosθ -(1) There is also one more parameter, which is Dislocation density (δ) is found to be 9.765 × 1014 lines/m2 calculated by using equation [20-22] δ = 1/D2 - (2) Fig XRD pattern of microwave-assisted green synthesis V2O5 nanoparticles Figure shows the FTIR spectrum of V2O5 nanoparticles It displayed that the characteristic peaks of vanadium oxide for V2O5 NPs appeared at The band at 497 cm-1 is attributed to (V-O-V) stretching vibration of terminal oxygen bonds and those around 988 cm-1 is attributed to (V=O) the vibration of doubly coordinated oxygen bonds stretching, and the band at 1615 and 3222 cm-1 were ascribed to bending vibrations of water molecules, other bands at 1425 cm-1was assigned with carbonate appearing due to the contact of the product with atmosphere Principally, the discernible peaks assigned as shown in Fig were unique bands for V2O5, which is quite reliable with previously reported results [23-26]

synthesis with subsequent heat treatment Surface morphology and shape of microwaveassisted green synthesis V2O5 nanoparticles were studied by SEM and TEM SEM analysis confirmed the particle sizes and micro-surface morphologies of the resultant V2O5 NPs were influenced by agglomeration i.e irregular bunch of particles were spread out in the nanometre range shown in Fig 3a From TEM, can observe that the particles appeared spherical shape and size was in the range of 23 nm (Fig 3b) Fig (a) SEM and (b) TEM images of microwave-assisted green synthesis V2O5 nanoparticles 3.3 Electrochemical

V2O5 are shown in Fig 4, which gives evidence for the redox couple and structural phase transition during electrochemical intercalation reaction Fig suggests the CVs of V2O5 nanomaterials at a scan rate (0.1 mV s−1) in the potential range of 1.5–4 V vs Li+/Li possess peaks at 3.65, 2.16 in the first cathodic scan is assignable to lithium insertion (lithiation) process From the second cycle, the intensity of the peak was observed In the anodic part of the scan cycle, the peak at 2.37, 3.11 and 3.81 V assigns to the delithiation process Charging existed for the reverse phase transformation due to deintercalation from γ-LiV2O5 to ε-LiV2O5 (3.11 V) and α-V2O5 (3.81 V) Incomplete redox reactions were responsible for lower cyclic stability [27-29] The insertion/extraction behavior of lithium

1.5–4.0 V vs Li/Li+ (Fig 5) Galvanostatic cycling studies reveal the performance of the battery The initial charge capacities acquired from these data is 333 mAhg-1 The discharge capacity maintains to decrease up to 50 cycles and the charge capacity obtained at the end of 50 cycles is 222 mAhg-1 Fig Galvanostatic charge-discharge profiles at a current rate of C/10 Fig shows the columbic efficiency of 50 cycles at a constant current rate of C/10, which depicts the remarkable performance of V2O5 nanomaterials as the anode in LIBs The initial lithiation capacity of V2O5 was 335 mAhg-1, later eventually reached 225 mAhg-1 at 50th cycle Gradually capacity maintained the stabilization; it retained 95% at its 50th cycle and faded only 5% related to the 30th cycle Table A comparison of battery
