چکیده
In this study, high nickel layered LiNi0.8Co0.1Mn0.1O2 cathode materials for lithium-ion batteries were modified by yttrium doping and poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) coating. The effects of PEDOT:PSS coating on the structural electrochemical properties material investigated compared. substitution with an electrochemically inert was confirmed to be successful in stabilizing structure framework. Moreover, surfaces particles a conductive polymer, PEDOT:PSS, improved capacity retention, thermal stability, impedance increasing its ionic electric conductivities. Keywords: Yttrium Doping, Conductive Polymer Coating, Cathode Material

Er-Doped LiNi0.5Mn1.5O4 Cathode Material with Enhanced Cycling Stability for Lithium-Ion Batteries
The Er-doped LiNi0.5Mn1.5O₄ (LiNi0.495Mn1.495Er0.01O₄) sample was successfully prepared by citric acid-assisted sol-gel method with erbium oxide as an erbium source for the first time. Compared with the undoped sample, the Er-doped LiNi0.5Mn1.5O₄ sample maintained the basic spinel structure, suggesting that the substitution of Er3+ ions for partial nickel and manganese ions did not change the i...
متن کاملGold-conductive polymer nanoparticles: a hybrid material with enhanced photonic reactivity to environmental stimuli.
We have designed a simple synthetic procedure to encapsulate colloidal gold nanoparticles by electrostatic adsorption with water-soluble poly(aniline-2-carboxylic acid). The composite nanoparticles are stable in aqueous buffer and retain the respective optical reactivity of the gold colloid to refractive index increases, and of the conductive polymer to pH changes and oxidoreduction. The new co...
متن کاملPromising Candidates for Lithium Ion Batteries: High Nickel Lithium-Rich Layered Cathode Nanomaterial
Over the past decade, much attention has been paid to the development of lithium-ion batteries (LIBs) owing to the increasing demand for power sources with higher energy and power density. LiCoO2 has been one of the most widely used cathode materials for its easy synthesis and excellent reversibility since the commercialization of LIBs. However, LiCoO2 also suffers from many drawbacks such as h...
متن کاملIonic Polymer-Coated Laccase with High Activity and Enhanced Stability: Application in the Decolourisation of Water Containing AO7
Eliminating dyes in environmental water purification remains a formidable challenge. Laccase is a unique, environmentally friendly and efficient biocatalyst that can degrade pollutants. However, the use of laccase for the degradation of pollutants is considerably limited by its susceptibility to environmental changes and its poor reusability. We fabricated a novel biocatalyst (LacPG) by coating...
متن کاملElectronic Transport in Lithium Nickel Manganese Oxide , a High - Voltage Cathode Material for Lithium -
Potential routes by which the energy densities of lithium-ion batteries may be improved abound. However, the introduction of Lithium Nickel Manganese Oxide (LixNi1i/2Mn3/2O4, or LNMO) as a positive electrode material appears to be one of the shortest. LNMO is a high-voltage material, with a voltage of 4.7V, and thus offers a significant energy density boost without straying far outside of the s...
