One-dimensional MLi₂Ti₆O₁₄ Nanomaterials Synthesis And Its Lithium Storage Properties

In the modern life,people cannot leave the mobile phone,computer which with lithium ion batteries as energy storage devices,human being use own wisdom to create highly civilized society and abundant social wealth.But it is difficult that the electronic products are to meet restrictions because of the limit service life of lithium-ion battery on the use fixed number of year,but the manufacture of these electronic products took a certain scarce resources,and recovery is difficult stage,it is imperative to increase the service life of lithium ion batteries.In the progress of material chemistry,nanotechnology has been applied to the one-dimensional nanomaterials in the development of long-life lithium-ion battery.One-dimensional nanomaterials own unique morphology structure and have characteristics of large specific surface area,one-dimensional nanomaterials is not easy to reunite,that can maintain the stability of the lithium ion battery materials.So using one-dimensional nanomaterials owning long service life of the lithium ion battery can be developed.Based on one-dimensional nanomaterials for extending the service life of the lithium ion battery of new concept,this article use the electrostatic spinning technique was used to prepare as lithium ion battery anode material of one-dimensional nanomaterials.This paper expounds the use of electrostatic spinning technique was used to prepare MLi₂Ti₆O₁₄?M = Pb,Ba,2Na?nanofibers,the method of using XRD,SEM,TEM and EDX mapping test hand representation for the chemical properties of material preparation.With the constant current charge and discharge test preparation of nanomaterials by electrochemical performance.Part of the materials are by in-situ technology to explore the working mechanisms in lithium ion batteries.In this paper,the specific research work are as follows:The synthesis and lithium storage properties of one-dimensional PbLi₂Ti₆O₁₄ nanomaterials.The source of lithium,lead source,titanium made electrical source are dissolved in a suitable solvent,then add PVP dope,adjust the electrospinning parameters,electrostatic spinning,put getting one-dimensional composites under a certain heating system in the muffle furnace to get one-dimensional PbLi₂Ti₆O₁₄ nanomaterials and such as XRD,SEM,TEM and EDX mapping of material chemistry.In order to getting the one dimensional nanomaterials for lithium ion battery anode material simulation,and explore the lithium storage performance and find larger ascension cycle performance.The synthesis and lithium storage properties of one-dimensional BaLi₂Ti₆O₁₄ nanomaterials.It is obtained by the method of electrostatic spinning organic-inorganic nanometer fiber,onedimensional BaLi₂Ti₆O₁₄ nano materials is obtained by calcining and such as XRD,SEM,TEM and EDX mapping,XPS characterization of materials chemistry.In order to getting the one dimensional nanomaterials for lithium ion battery anode material simulation,and explore the lithium storage performance.By in situ technology preliminary explore battery lithium ion in the work of the state.After charge and discharge loop 800 times,discharge specific capacity loss was 0.153‰ per each lap.The synthesis and lithium storage properties of one-dimensional Na2Li₂Ti₆O₁₄ nanomaterials.Is obtained by the method of electrostatic spinning organic-inorganic nanometer fiber,onedimensional Na2Li₂Ti₆O₁₄ nano materials is obtained by calcining and chemical characterization of a series of materials,and carry on the performance of lithium storage.By situ-XRD technology to explore the working state of lithium ion batteries.In charge and discharge cycle after 800 times,the coulomb efficiency remain close to 100%.
