Abstract:
Lithium- ion batteries have come decreasingly popular in recent times due to their high energy viscosity and long cycle life. still, the demand for advanced energy viscosity and briskly charging times has led to a need for new and advanced electrode accoutrements . In this study, we probe a compound material of nickel- substituted manganese oxide and graphene oxide as a implicit seeker for high- performance lithium- ion batteries. The compound material was synthesized using a simple hydrothermal system and characterized using X-ray diffraction( XRD), surveying electron microscopy( SEM), RAMAN spectroscopy, Energy Dispersive Spectroscopy( EDX), Fourier transmission infrared spectroscopy( FTIR) and Cyclic Voltammetry( CV). XRD results verified the single phase boxy structure of the material and also confirm the successful doping of Ni to manganese oxide and graphene oxide compound. SEM results showed that the compound material had a well- defined liquid structure and a invariant flyspeck size distribution. EDX analysis also verified the successful negotiation with no other contaminations. FTIR analysis showed the immersion band of tetrahedral and octahedral spots at 658cm- 1 and 543cm- 1 independently for manganese oxide and shifted towards lower frequency for other samples. Electrochemical tests were performed on the compound material using coin cells, and the results showed bettered electrochemical performance compared to pure manganese oxide. The compound material displayed a advanced specific capacity of787.76 F/ g. The bettered electrochemical performance of the compound material can be attributed to several factors. The presence of nickel in the compound material helps to ameliorate the conductivity and enhances the structural stability of the electrode material. The graphene oxide, on the other hand, helps to ameliorate the electrode/ electrolyte interface and provides fresh active spots for lithium- ion insertion. The results demonstrate that the nickel- substituted manganese oxide and graphene oxide compound material has great eventuality for use in high- performance lithium- ion batteries.
