The significance of aqueous binders in lithium-ion batteries

Achieving the Interface Stability of LiMn2O4 Cathode Using Aqueous Polyacrylic Acid/acrylate Copolymer and Nanoscale CaCO3 to Improve the High‐Temperature Cycling and Storage Performance of Lithium‐Ion Batteries

“…The weight and volume of PVDF expand after being soaked in the electrolyte, which can reduce the adhesion between active coating and aluminum foil. [ 32 ] After the plates using binder B and binder C soaked in the electrolyte, the thickness of plates does not change obviously with the extension of soaking time. The low expansion rate of the cathode plate is beneficial to maintain the stability of the electrochemical performance of the battery.…”

Crosslinked Chitosan Binder for Sustainable Aqueous Batteries

“…In the present study, we have chosen a natural polymer to evaluate the possibility of using it as a water-soluble binder, to reduce the impact of electrode manufacturing processes, and to study the effect of chemical crosslinking to avoid binder dissolution in aqueous batteries [8,9]. It is known that acetic and formic acid are effective for the dissolution of chitosan in water.…”

“…This cost also includes the process to produce electrodes that consist of a deposition of a slurry of active materials on current collectors, evaporation of the organic solvent contained in the slurry, condensation of the solvent for its recovering and reuse, and final electrode drying. As already pointed out [8], the use of a toxic and high-boiling organic solvent for electrode preparation is the most common procedure. However, for moving toward more sustainable batteries, it is necessary to change from the beginning, starting from materials and processes.…”

“…However, for moving toward more sustainable batteries, it is necessary to change from the beginning, starting from materials and processes. Several studies have been carried out on aqueous processes using water-processable binders [8][9][10][11]. Many of these binders come from natural sources or wastes, thus eliminating the need of using fluorinated binders that usually require toxic organic solvents, unless water-soluble fluorinated binders are used [12,13].…”

High Performance Study of Lithium Carboxymethylcellulose as Water‐Soluble Binder for Lithium Supplementation in Lithium Batteries

“…The radius of the lithium ion is small, and the conductivity is high. [22] At the same time, it can avoid the phenomenon that CMC-Na is used as a binder for some electrode materials, and the charge-discharge efficiency of the battery decreases under the condition of long-term discharge, resulting in a decrease in the charge-discharge specific capacity and a rapid decrease in the cycle characteristics. [11,15] Because CMC-Na is an ionic polymer, it is easy to ionize sodium ions, which may exchange reactions with lithium ions on the surface of the carbon negative electrode, thereby reducing the overall content of freely mobile lithium ions, resulting in overall lithium-ion desorption and intercalation.…”
