A mesoporous conjugated polymer based on a high free radical density polytriphenylamine derivative: its preparation and electrochemical performance as a cathode material for Li-ion batteries

Abstract

A novel polytriphenylamine derivative has been prepared, which, as a cathode, exhibits a well-defined multistage discharge voltage plateau, an improved capacity and an enhanced rate performance.

Polymer Electrode Materials for High‐Performance Lithium/Sodium‐Ion Batteries: A Review

“…Su et al synthesized poly(4,4′,4″‐ tris ( N , N ‐diphenyl‐amino)triphenylamine (PTDATA) with a specific mesoporous morphology . PTDATA exhibited a specific surface of 560.58 m 2 g −1 , which was greater than that of PTPA (5.62 m 2 g −1 ).…”

Highly Thermal Stable Phenolic Resin Based on Double-Decker-Shaped POSS Nanocomposites for Supercapacitors

“…A similar phenomenon appeared in the CV curve of the carbon material derived from PDDSQ-50 ( Figure 8 e), suggesting a combination of pseudocapacitance and EDLC. Because of the many electroactive centers (e.g., N and O atoms and electron-rich phenyl rings) in the carbon material derived from the pure PDDSQ, reversible radical redox procedures occurred during the charging and discharging processes [ 47 ]. Furthermore, the current density of the carbon material derived from pure PDDSQ increased dramatically upon increasing the sweep rate, while the shape of its CV curve was retained ( Figure 8 c), indicating good rate capability and facile kinetics [ 48 , 49 ].…”

Multifunctional Hypercrosslinked Porous Organic Polymers Based on Tetraphenylethene and Triphenylamine Derivatives for High-Performance Dye Adsorption and Supercapacitor

“…In addition, the DPT-HPP sample possessed the redox-active triphenylamine units that can undergo a reversible redox process [ 30 ]. As previously reported, in two successive one-electron steps, the tetraphenylethene (TPE) can undergo a redox process, forming its reduced form [ 70 ], while the triphenylamine (TPA) possesses a nitrogen atom as its electroactive center connected, to three electron-rich phenyl rings, in which a reversible radical redox process occurs during charge and discharge processes [ 39 , 71 , 72 ].…”
