“…[22][23][24][25][26][27] To our knowledge, only in a recent paper a PIL copolymer in nanoparticulate form have been examined as binder for electrode of LIBs. 28 In spite of the exciting and encouraging progress reported when applied to the cathode, these nanoparticle binders were nevertheless claimed to decompose under operation. It should however be possible to avoid this degradation when the binders are correctly designed by polymer chemistry.…”

A series of poly(ionic liquid)s (PILs) were used as binders for lithium-ion battery (LIB) with a LiFePO 4 cathode to explore their role and benefits in a model electrochemical energy storage system. The PILs are imidazolium-based and bear different main chain structures and alkyl substituents. The results nicely show that PILs both improve the cycling stability and specific capacity. When carefully designed, they especially exhibited a usually high electrochemical stability against oxidative conditions (¼4.0 vs. Li/Li + ). It is found that the PIL binders together with carbon additive form very effective Li + and electron conducting pathways in the electrode. These finding illustrate that binder with carefully designed chemical structures can have a high potential to improve the electrochemical performance even of current rechargeable battery systems. A better Li + and electron conduction is however of general importance for a wide spectrum of electrochemical devices.

“…Currently, there is a growing interest in the design and preparation of polymeric ionic liquids (PILs) as safe electrolytes for the application in electrochemical devices, such as Li and Li-ion battery [1][2][3][4][5][6][7], solar-cells [8,9], fuel cells [10][11][12] and supercapacitors [13,14]. This is mainly motivated by the combination of both the advanced properties of conventional ionic liquids (ILs) and the flexibility and mechanical properties of polymers [15][16][17].…”

“…Furthermore, the influence of ILs on corrosion intensity has been widely confirmed. Various researchers show that addition of low doses of ILs can inhibit the corrosion of metals or alloys [27,28], widen the potential window of the electrolyte [29], or act as a binder for electrodeactive materials [30].…”

The influence of selected types of ammonium ionic liquid (AIL) additives on corrosion and functional parameters of lead-acid battery positive electrode was examined. AILs with a bisulfate anion used in the experiments were classified as protic, aprotic, monomeric, and polymeric, based on the structure of their cation. Working electrodes consisted of a lead-calcium-tin alloy utilized in the industry for manufacturing current collectors of positive electrodes in lead-acid batteries (LABs). This alloy was used in the first part of the study for the evaluation of corrosion intensity and stability of electrolyte with AIL additives. In the second part, the grid made of the examined alloy was covered with positive active mass, the composition of which was modified by selected AIL. The selection of an appropriate substance was made based on parameters such as corrosion potential, corrosion current, polarization resistance, and hydrogen and oxygen evolution potentials. Techniques such as linear sweep voltammetry, corrosimetry, and electrochemical impedance spectroscopy were used. The conducted measurements revealed that polymeric AIL additive had an exceptionally positive influence on the inhibition of the corrosion process in LAB and electrochemical window of the electrolyte. The influence of this compound on the specific capacity and resistance of the active mass was also discussed.
