Lithium-ion conduction in elastomeric binder in Li-ion batteries

Journal of Solid State Electrochemistry, 2006
This paper describes two kinds of elastomeric binders which are styrene–butadiene (ST–BD) copolymer and 2-ethylhexyl acrylate–acrylonitrile (2EHA–AN) copolymer for electrode materials of rechargeable Li-ion batteries. These elastomeric binders were swollen by electrolyte solution (EC/DEC=1/2, 1 M LiPF6), and 2EHA–AN copolymer retained larger amount of ...

Functional polyethylene separator with impurity entrapment and faster Li+ ions transfer for superior lithium-ion batteries

Journal of Colloid and Interface Science, 2022
An organic/inorganic hybrid coating consisting of molecular sieve (MS)/sulfonated melamine formaldehyde condensate (SMF) is fabricated on the polyethylene (PE) separator by a simple dip-coating process. The MS/SMF coating with high polarity enhances the electrolyte uptake of PE separator, and therefore favors higher ionic conductivity and Li ...

Probing Li-ion concentration in an operating lithium ion battery using in situ Raman spectroscopy

Journal of Power Sources, 2020
Abstract In situ Raman spectroscopy was employed to probe Li-ion concentration in liquid electrolytes at the cathode LiFePO4 particle surface in an optically transparent lithium ion battery. A Raman laser beam size of 2 μm was utilized so that Li-ion transport dynamics at the particle-level could be revealed. The variation of Li+ concentration in the

Improved Li-ion diffusion process in TiO2/rGO anode for lithium-ion battery

Journal of Alloys and Compounds, 2017
Abstract The low diffusion rate of pure TiO 2 affects the inferior electrochemical performance such as cycling capacity and rate capability. Many works have been focusing on the material structural control to solve this problem, but the specific mechanism of the electrochemical process still needs further study.

Estimation on diffusion coefficient of lithium ions at the interface of LiNi0.5Mn1.5O4/electrolyte in Li-ion battery

Ionics, 2014
This research tried to estimate diffusion coefficient for lithium ions through the surface of the spinel LiNi0.5Mn1.5O4 by spin-polarized total energy calculation. In addition, calculated result by this ab initio model was compared with a semi-empirical model. Both of these models predicted diffusion coefficient for lithium ions at the interface of the

A study of Li-ion diffusion kinetics in the fullerene-coated Si anodes of lithium ion batteries

Physica Scripta, 2010
The diffusion coefficient of lithium ions in fullerene-coated silicon thin film electrodes, prepared by the plasma-assisted deposition technique, was estimated by a specific electrochemical measurement known as cyclic voltammetry (CV) and then compared with that of a bare silicon film used as the anode in lithium ion batteries.
