Ion storage performance of a polymer for mono-, di- and tri-valent metal ions in non-aqueous electrolytes

Abstract

A cost-effective quinone-pyrrole conjugated polymer is utilized as electrode for non-aqueous Al, Zn and Li-ion batteries. Reversible capacities of 120 mAh g-1 at 50 mA g-1 for Al-ion batteries and...

Morphology and size control of an amorphous conjugated polymer network containing quinone and pyrrole moieties via precipitation polymerization

“…The BQ-Py polymers were used for electrochemical applications, such as in a HER catalyst, battery, and photoanode, by our group and other groups. 13,[15][16][17][18] However, the size and morphology were not controlled in the previous studies because the polymerization was performed in an inhomogeneous system, such as a combination of a BQ solid and Py vapor (Fig. 1b).…”

Solvothermal Polymerization and Electrochemical Behavior of Conjugated Polyimide with High Electronic Conductivity and Low Solubility

“…However, such small molecules are easily dissolved in an organic electrolyte, leading to a low energy density and poor cycle stability, and the low electronic conductivity leads to poor utilization of the active material [5–7] . Polymerization of small molecules into conjugated polymer electrode materials may solve all these problems at the same time [8,9] …”

“…[5][6][7] Polymerization of small molecules into conjugated polymer electrode materials may solve all these problems at the same time. [8,9] The structurally diverse and controllable nature of polymers enables one to obtain the optimized structures that will further improve the electrochemical properties of electrode materials. Examples include the introduction of electron-donating or electron-absorbing substituent groups to regulate the discharge voltage, [10,11] the use of different precursors to prepare porous structures that promote ion transport, and the fabrication of self-supporting flexible electrodes.…”

A metal organic framework-derived octahedral Cu1.95S@CoS2 for secondary batteries displaying long cycle life and stable temperature tolerance

“…3 In addition, Al is the most abundant metal element in the earth's crust, and its abundant content and low cost provide prospects for its application in energy storage. 4 Recently, Al-ion batteries have been considered as a promising energy-storage system.…”
