Abstract

In silicon-based lithium-ion batteries, polymeric binders play the crucial role of “gluing” the electrode matrix together, providing strong adhesion between the active silicon (Si) and conductive carbon particles and keeping them in electrical contact, despite considerable volumetric changes during cycling. While remarkable progress has been seen in the development of binders, improved cycling performance is still needed to fully enable Si anodes. Achieving that end requires in turn a better understanding of the relationship between binder properties and cell cycling performance. Here, we describe a novel polymer binder, poly(4-vinylbenzoic acid) (P4VBA), developed by re-engineering the widely used poly(acrylic acid) (PAA) binder to explore that relationship. The modified structure produces a binder that is more compatible with 1-methyl-2-pyrrolidinone (NMP) slurries and affords much improved cycling performance of the fabricated cells. Compared with PAA binders, P4VBA provides higher initial and average capacities and better capacity retention. While P4VBA offers an interesting alternative to wet processing of the Si-based electrodes, this re-engineered binder is an initial effort to develop a better binder material by exploring the relationship between binder and cell cycling performance.

Re-Engineering Poly(Acrylic Acid) Binder toward Optimized Electrochemical Performance for Silicon Lithium-Ion Batteries: Branching Architecture Leads to Balanced Properties of Polymeric Binders

Journal Article Jiang, Sisi ; Hu, Bin ; Shi, Zhangxing ; ... - Advanced Functional Materials

Silicon is a promising anode material for lithium-ion batteries with its superior capacity. However, the drastic volume changes during lithiation/delithiation cycles hinder the cycling performance, resulting in particle pulverization, conductivity loss, and an unstable electrode-electrolyte interface. In this work, a series of synthetic polymeric binders, poly(acrylic acid-co-tetra(ethylene glycol) diacrylate)-featuring a poly(acrylic acid) (PAA) backbone branched via tetra(ethylene glycol) diacrylate (TEGDA)-are developed that edge toward evidencing well-balanced properties to confront capacity fading in Si-based electrodes. The incorporation of ether chain not only leads to the branching architecture of the PAA backbone, thus affecting its mechanical properties, but also promotes the conductivitymore »« less

Understanding of pre-lithiation of poly(acrylic acid) binder: Striking the balances between the cycling performance and slurry stability for silicon-graphite composite electrodes in Li-ion batteries

Journal Article Hu, Bin ; Jiang, Sisi ; Shkrob, Ilya A. ; ... - Journal of Power Sources

Poly(acrylic acid) (PAA) is widely used as a polymer binder for high capacity silicon (Si) anodes in Li-ion batteries. When used, the carboxyl (-CO2H) groups of PAA can be partially lithiated (known as pre-lithiation treatment), which is believed to facilitates lamination process, especially for production on a large scale. However, such treatment impacts numerous physico-chemical properties of the PAA binder that affect the cycling performance of the electrode. Here we seek to quantify the pre-lithiation treatment effect on Li-ion cells containing Si-graphite composite electrodes. The electrochemical cycling results indicated that such pre-lithiation treatment of PAA can undermine the cycling performance,more »« less

A chemical switch enabled autonomous two-stage crosslinking polymeric binder for high performance silicon anodes

Journal Article Shi, Zhangxing ; Liu, Qian ; Yang, Zhenzhen ; ... - Journal of Materials Chemistry. A

Silicon (Si) is a promising high-capacity anode material for high-energy-density lithium-ion batteries. However, the drastic volumetric changes of Si upon lithiation/delithiation hinder the practical use of Si anodes. Although adhesive polymeric binders, such as poly(acrylic acid) (PAA), mitigate this issue, the cycling performance of the fabricated Si anodes is still far from meeting the criteria of practical applications. In this study, we present a novel polymeric binder system for Si anodes consisting of PAA, a chemical switch (ammonia, NH₃), and a crosslinker (branched polyethylenimine, PEI). The crosslinking between PAA and PEI is switched off in the slurry, which can thenmore »« less

Restorable Neutralization of Poly(acrylic acid) Binders toward Balanced Processing Properties and Cycling Performance for Silicon Anodes in Lithium-Ion Batteries

Journal Article Shi, Zhangxing ; Jiang, Sisi ; Robertson, Lily A. ; ... - ACS Applied Materials and Interfaces

Neutralization of poly(acrylic acid) (PAA)-based binders using lithium hydroxide is a common strategy for fabricating silicon anode laminates, which improves rheological properties of slurries toward high-quality electrode laminates. However, the significantly increased basicity causes degradation of Si particles while the irreversible conversion of carboxylic acid groups to lithium carboxylates undermines the binding strength, collectively leading to adverse cycling performance of the fabricated Si anodes. Herein, a novel neutralization process for PAA binders is developed. A weak base, ammonia (NH₃), was discovered as a neutralizing agent that still promotes rheological response of binder solutions but results in a reduced pH increase.more »« less

Adhesive Polymers as Efficient Binders for High-Capacity Silicon Electrodes

Journal Article Pan, Yiyang ; Ge, Sirui ; Rashid, Zahid ; ... - ACS Applied Energy Materials

The major cause for capacity fading of silicon nanoparticle (SiNP)-based electrodes is the immense pressure applied toward the conductive networks during the charge/discharge process. While numerous efforts have been devoted to investigating different types of polymer binders, the rational design of an adhesive binder with pressure sensitivity has rarely been reported. Herein, a series of pressure-sensitive adhesives (PSAs) synthesized via copolymerization of 2-ethylhexyl acrylate (2-EHA) and acrylic acid (AA) are evaluated as polymer binders for SiNP-based electrodes. The balance between the density of interaction groups and viscoelastic properties is systematically investigated for efficient binding performance. The SiNP-based electrode using PSAmore »« less
