“…The deprotonation-induced n-doped of PANI needs cations, such as Na + and K + , to compensate for the negatively charged nitrogen atoms. 120 Li-doped PANI (lithium emeraldinate) was prepared vis a lithium-proton exchange on the emeraldine base (EB) in an anhydrous lithium-based electrolyte, since the EB form had distinct interaction with Li cations (Figure 7d). This lithium emeraldinate positive electrode can be discharged to 4.25 V vs. Li + /Li and displayed a coulombic efficiency of 99% after 400 cycles.…”

“…Research of PANI commonly centers on p-doped states (transitions from LB to ES, then ES to PNB) which involves simple acid–base reactions in water or protic media (Figure c). The deprotonation-induced n-doping of PANI needs cations, such as Na + and K + , to compensate for the negatively charged nitrogen atoms . Li-doped PANI (lithium emeraldinate) was prepared via a lithium-proton exchange on the emeraldine base (EB) in an anhydrous lithium-based electrolyte, since the EB form had distinct interaction with Li cations (Figure d).…”

Rapid growth of smart electronics and implantable medical devices markets has driven the development of next-generation sustainable, flexible, or implantable batteries. Conducting polymers with unique mechanical and electronic properties offer new possibilities and have attracted great attention. In this review, we discuss approaches used to tune conducting polymers at the molecular level for designated properties and applications such as improved electrochemical performance, and we discuss approaches used to tune conducting polymers at the molecular level to enhance selected properties for applications such as lithium/sodium ion batteries, biodegradable electrodes or enhanced solution processability for advanced manufacture of such structures. We provide here insights into the molecular structureelectrochemical performance relationships. Finally, we present perspectives on the further development of conducting polymer materials for these novel batteries.

“…Since the discovery of electrically conducting polymers (ECPs) in 1977, the polymerization methods, chemical modication of these polymers, and their application elds have progressed signicantly. [1][2][3][4][5][6] Among them, aromatic polymers such as polypyrrole (PPy), polythiophene (PTh), and polyaniline (PANI) are particularly of interest, in part due to their unique physicochemical properties. [7][8][9][10][11][12] In this respect, PANI has been intensively explored both theoretically, and experimentally, and is considered as one of the most promising materials due to its unique physicochemical properties such as excellent redox reversibility, good thermal and environmental stability, controllable electrical conductivity, high energy density, ease of synthesis, and low cost.…”

The discovery of conducting lithium‐doped polyaniline with reversible redox chemistry allows simultaneous unprecedented capacity and stability in a non‐aqueous Li battery. This compound (lithium emeraldinate) was synthesized by lithium–proton exchange on the emeraldine base in an anhydrous lithium‐based electrolyte. A combination of UV/Vis‐NIR spectroelectrochemistry, XPS, FTIR, and EQCM characterization allowed a unified description of the chemical and electrochemical behavior, showing facile charge delocalization of the doped states and the reversibility of the redox processes in this form of polyaniline. From a practical point of view, lithium emeraldinate behaves as a high‐capacity organic active material (230 mAh g−1) that enables preparation of relatively thick composite electrodes with a low amount of carbon additives and high energy density (460 Wh kg−1). Concomitantly, at 1C rate, 400 cycles were achieved without significant capacity loss, while the coulombic efficiency is greater than 99 %.
