Available in PDF, EPUB and Kindle. Book excerpt: The growing market for energy storage devices raises the demand for lithium ion batteries (LIBs) with higher energy density and power density. Enhanced LIB performance requires the improvement of the electrode materials, so that the use of conductive polymer binders becomes an important option when the choice of active materials is limited. Compared to a traditional binder, such as PVDF, the advanced polymer binders exhibit not only electrochemical stability and adhesion strength, but also ionic/electronic conductivity for a thick electrode and/or a high-capacity electrode. Such considerations make the 3,4-propylenedioxythiophene-2,5-dicarboxylic acid family (ProDOT) and poly{[N,N'-bis(2-octyldodecyl)-naphthalene-1,4,5,8-bis (dicarboximide)-2,6-diyl]-alt-5,5'-(2,2'-bithiophene)} family (P(NDI2OD-T2)) of polymers attractive candidates for the LIB binders.Various experiments were designed and conducted on the selected binder candidates in order to evaluate different aspects of polymer behavior. The material properties are investigated based on thin film three-electrode systems, while the half-cell and full-cell experiments represent how the binder influences the electrodes and practical batteries, respectively. According to those experiments, the Hexyl-ProDOT polymer shows excellent mixed ionic/electronic conductivity and surface-controlled electrochemical reaction mechanism, which significantly enhances the performance of LiNi0.8Co0.15Al0.05O2 (NCA) electrode and improves the NCA-Nb2O5 battery. However, the effectiveness of P(NDI2OD-T2) is limited by its poor stability at low voltage.
Book Synopsis Conductive Polymeric Binder for Lithium-ion Battery Anode by : Tianxiang Gao
Download or read book Conductive Polymeric Binder for Lithium-ion Battery Anode written by Tianxiang Gao and published by . This book was released on 2015 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tin (Sn) has a high-specific capacity (993 mAhg-1) as an anode material for Li-ion batteries. To overcome the poor cycling performance issue caused by its large volume expansion and pulverization during the charging and discharging process, many researchers put efforts into it. Most of the strategies are through nanostructured material design and introducing conductive polymer binders that serve as matrix of the active material in anode. This thesis aims for developing a novel method for preparing the anode to improve the capacity retention rate. This would require the anode to have high electrical conductivity, high ionic conductivity, and good mechanical properties, especially elasticity. Here the incorporation of a conducting polymer and a conductive hydrogel in Sn-based anodes using a one-step electrochemical deposition via a 3-electrode cell method is reported: the Sn particles and conductive component can be electrochemically synthesized and simultaneously deposited into a hybrid thin film onto the working electrode directly forming the anode. A well-defined three dimensional network structure consisting of Sn nanoparticles coated by conducting polymers is achieved. Such a conductive polymer-hydrogel network has multiple advantageous features: meshporous polymeric structure can offer the pathway for lithium ion transfer between the anode and electrolyte; the continuous electrically conductive polypyrrole network, with the electrostatic interaction with elastic, porous hydrogel, poly (2-acrylamido-2-methyl-1-propanesulfonic acid-co-acrylonitrile) (PAMPS) as both the crosslinker and doping anion for polypyrrole (PPy) can decrease the volume expansion by creating porous scaffold and softening the system itself. Furthermore, by increasing the amount of PAMPS and creating an interval can improve the cycling performance, resulting in improved capacity retention about 80% after 20 cycles, compared with only 54% of that of the control sample without PAMPS. The cycle is performed under current of 0.1 C.
Book Synopsis Conducting Polymers as Functional Binders for Lithium Ion Battery Positive Electrodes by : Pratik Ranjan Das
Download or read book Conducting Polymers as Functional Binders for Lithium Ion Battery Positive Electrodes written by Pratik Ranjan Das and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Lithium ion batteries have been successfully used in portable electronics applications. Their application areas are growing continuously. For their commercial application in electromobility and stationary storage, high energy density, high rate capability and long cycle life is required. This work demonstrates the improvement in energy density and rate capability of LiFePO4 composite positive electrodes by replacing conventional binders with conducting polymers such as polyaniline (PANI), poly-o-methoxy aniline (POMA), poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS). Conducting polymers act in a dual role as binder and conducting additive in the positive composite electrode. The capacity and charging rate capability of the electrodes are improved by using PANI and POMA. However, due to their inherent lower conductivity in the emeraldine state, complete replacement of carbon additive is not possible. On the other hand in this work it is shown that PEDOT:PSS is stable and highly conducting in the working potential window of LiFePO4 electrodes (2.8-4 V). Hence composite electrodes free of any carbon additive are prepared with PEDOT:PSS and LiFePO4. In order to understand the flow behaviour of composite slurries with different solid content; rheological measurements is performed with rheometer. All slurries show solid-like behavior due to formation of a network structure of LiFePO4 bridged by PEDOT:PSS chains. However, the solid loading of the slurries influences the distribution of the agglomerates and the binder affecting also the thickness, the adhesion and the electrical conductivity of the coatings casted from the different slurries under the same conditions. The optimum electrochemical performance is achieved with slurries containing 40 % solid loading. The electrochemical performance and the cycling stability of the composite electrodes are compared to the behaviour of conventional positive electrodes with carbon additives and PVDF binder. With increasing PEDOT:PSS content a decrease in the overvoltage and correspondingly an improvement in the rate capability is observed. Composite electrodes containing 8% PEDOT:PSS show comparable electrode capacity and better cycling stability as compared to conventional PVDF based system. engl.

Book excerpt: A family of carboxylic acid group containing fluorene/fluorenon copolymers is disclosed as binders of silicon particles in the fabrication of negative electrodes for use with lithium ion batteries.

Download or read book The Effects of Various Conductive Additive and Polymeric Binder Contents on the Performance of a Lithium-ion Composite written by and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamental electrochemical methods, cell performance tests, and physical characterization tests such as electron microscopy were used to study the effects of levels of the inert materials (acetylene black (AB), a nano-conductive additive, and polyvinylidene difluoride (PVDF), a polymer binder) on the power performance of lithium-ion composite cathodes. The electronic conductivity of the AB/PVDF composites at different compositions was measured with a four-point probe direct current method. The electronic conductivity was found to increase rapidly and plateau at a AB:PVDF ratio 0.2:1 (by weight), with 0.8:1 being the highest conductivity composition. AB:PVDF compositions along the plateau of 0.2:1, 0.4:1, 0.6:1 and 0.8:1 were investigated. Electrodes of each of those compositions were fabricated with different fractions of AB/PVDF to active material. It was found that at the 0.8:1 AB:PVDF, the rate performance improved with increases in the AB/PVDF loading, whereas at the 0.2:1 AB:PVDF, the rate performance improved with decreases in the AB/PVDF loading. The impedance of electrodes made with 0.6:1 AB:PVDF was low and relatively invariant.
