Special Issue Information

Dear Colleagues,

Rechargeable batteries, such as lithium-ion batteries, are considered as the candidate technologies for several industrial sectors including electric vehicles, consumer electronics, and stationary energy storage. Increasing the energy density and lifespan of rechargeable batteries, which are restricted by their key components, is crucial to their widespread applications. Except for anode and cathode materials, binders and additives are also critical components of rechargeable batteries that significantly affect whole battery performances, despite only accounting for a very small ratio of the entire electrode or electrolyte. Therefore, it is a big interest to explore new functional binders and additives and investigate their roles in rechargeable batteries.

This Special Issue focuses on the progress of functional binders and additives for rechargeable batteries, such as metal-ion batteries, metal batteries, and metal-air/sulfur batteries.

Potential topics include, but are not limited to:

New binders;
Mechanical property of binders;
Cross-linked polymeric networks;
Additives for low-temperature batteries;
Additives for high-voltage batteries;
Additives for electrocatalysis in batteries.

Abstract

Binders play a pivotal role in the production and the operation of lithium-ion batteries. They influence a number of key dispersion characteristics and battery parameters. In the light of growing interest in additive manufacturing technologies, binders were found to decisively govern the processability due to the induced complex non-Newtonian behavior. This paper examines the relevance of various binder derivatives for aqueous graphite dispersions that can be employed in inkjet printing. Two different carboxymethyl cellulose (CMC) derivatives with strongly deviating molecular weights were employed. The impact of the inherent polymer characteristics on the processability and the electrode characteristics were explored. Therefore, miscellaneous studies were carried out at the dispersion, the electrode, and the cell levels. The results revealed that the CMC with the lower molecular weight affected most of the studied characteristics more favorably than the counterpart with a higher molecular weight. In particular, the processability, encompassing drop formation and drop deposition, the cohesion behavior, and the electrochemical characteristics, were positively impacted by the low-molecular-weight CMC. The adhesion behavior was enhanced using the high-molecular-weight CMC. This demonstrates that the selection of a suitable binder derivative merits close attention. Full article

Could Commercially Available Aqueous Binders Allow for the Fabrication of Highly Loaded Sulfur Cathodes with a Stable Cycling Performance?

by Wenli Wei, Marzi Barghamadi, Anthony F. Hollenkamp and Peter J. Mahon

Abstract

In this review, the application of five commercially available aqueous-based binders including sodium carboxyl methyl cellulose (CMC), polyacrylic acid (PAA), polyvinyl alcohol (PVA), polyethylene oxide (PEO), and polyethyleneimine (PEI) as well as some representative custom (or purpose) synthesized functional binders used in lithium sulfur (Li-S) batteries is summarized based on the main evaluation criteria of cycling capacity, battery lifetime, and areal sulfur loading (and, consequently, energy density of the battery). CMC with SBR (styrene butadiene rubber) has been reported with promising results in highly loaded sulfur cathodes (>5 mg cm⁻² sulfur loading). PVA and PEI were confirmed to provide an enhanced adsorption of lithium polysulfides due to the interaction with hydroxyl and amine groups. No competitive advantage in electrochemical performance was demonstrated through the use of PAA and PEO. Water-based binders modified with polysulfide-trapping functional groups have complex fabrication processes, which hinders their commercial application. In general, achieving a high capacity and long cycling stability for highly loaded sulfur cathodes using commercial aqueous-based binders remains a significant challenge. Additionally, the scalability of these reported sulfur cathodes, in terms of complexity, cost, and stable electrochemical cycling, should be evaluated through further battery testing, particularly targeting pouch cell performance.
