“…5 The main purpose of the binder is to contain the active material and to provide structural stability. The most commonly used binders for this purpose in ESDs are fluorine-containing polymers [poly(vinylidene difluoride) (PVDF) 6 and poly(tetrafluoroethylene) (PTFE)], 7 styrenebutadiene rubber (SBR), 8 polyimides, 9 polyrotaxanes, 10 poly-(acrylate) derivates, 11,12 and amphiphilic copolymers. 13 Conducting polymer binders represent another category of binders with polyaniline (PANI), 14 polypyrrole (PPy), 15 and poly(3,4-ethylenedioxythiophene) (PEDOT) 16,17 being the most studied.…”

“…Emulsion polymerization for synthesis of binders has been used as a method for electrode applications. For example, Qi et al used in situ two-step emulsion polymerization to synthesize poly(pyrrole/acrylonitrile- co -butyl acrylate) as an electrochemical double-layer capacitor electrode in which polypyrrole functioned as an electrically conducting filler for a water-based (acrylonitrile- co -butyl acrylate) binder. They reported a capacitance retention of ∼88.5% after 10,000 cycles (3 V window) despite the presence of only 1 wt % active material [polypyrrole relative to poly(acrylonitrile- co -butyl acrylate)].…”

Robust and electrochemically stable electrodes are critical for emerging energy storage devices. In this work, we describe the synthesis and characterization of an asymmetric pseudocapacitor with a P(nBA-stat-BzMA)/reduced graphene oxide (rGO, 5 wt %) nanocomposite cathode incorporating a low content of lignosulfonate (LS, 5 wt %) and a P(nBA-stat-BzMA)/rGO anode. Besides the advantageous green source and low cost of LS, its properties as a binder and its redox groups contribute to the electrochemical performance improvement of the pseudocapacitor. First, the electrochemical optimization and characterization of an asymmetric unit cell is performed. Subsequently, a series of 10 unit cells are arranged in a "stack of cells"; electrochemical tests show this assembly to have a capacitance of 4.90 F cm −3 (8.60 F g −1 ), maximum power of 610 W kg −1 , energy of 4.32 W h kg −1 , loss of electroactivity of 1.8%, capacitance retention of 98%, and Coulombic efficiency of 108% after 1000 charge−discharge cycles at a constant current of 0.12 A cm −3 . Morphological analysis revealed an increase in surface roughness after LS incorporation within the cathode. Electrode−electrolyte resistances were calculated via electrochemical impedance spectroscopy, which allowed us to propose a model of electrode−electrolyte interaction for this system.

The upsurging demand for electric vehicles and the rapid consumption of lithium‐ion batteries (LIBs) calls for LIBs to possess high energy density and resource sustainability. The former requires the usage of electroactive materials with high capacity and the maximum amount within the fixed electrode volume. The latter essentially creates a closed‐loop circulation scenario for electroactive materials. In all aspects, binders are of practical significance in bonding electroactive materials, maintaining electrode integrity and detaching electrode slurry from the current collector. Currently, the key role of binders in enhancing the electrochemical behavior of sustainable high‐capacity electroactive materials has been recognized. Meanwhile, binders that are designed for easy and cost‐effective recycling of electroactive materials are gradually reported. Herein, recently developed binders that hold promises in establishing sustainable high‐energy‐density LIBs are summarized. The role of binder in facilitating easy separation of electroactive materials are first highlighted. Subsequently, special attention is paid to conductive binders, contributing to less battery chemistries and higher energy density of electrode. Additionally, progress of emerging binders in high‐capacity electroactive materials are also reviewed. It is believed that the advances in binders will open up opportunities for establishing a sustainable high‐energy‐density battery economy.
