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

A cost-effective quinone-pyrrole conjugated polymer is utilized as an electrode for non-aqueous Al, Zn and Li-ion batteries. Reversible capacities of 120 mA h g at 50 mA g for Al-ion batteries and 108 and 175 mA h g for Zn and Li-ion batteries, respectively, at 100 mA g are observed. Thousands of stable cycles were obtained at 1000 mA g current density, providing sufficient evidence for a range of applications of the polymer in electrochemical energy storage.

Off-Planar, Two-Dimensional Polymer Cathode for High-Rate, Durable Rechargeable Magnesium Batteries.

Rechargeable magnesium batteries are of considerable interest due to their high theoretical capacity, and they are projected as good alternates for stationary energy storage and electric vehicles. Sluggish Mg kinetics and scarce availability of suitable cathode materials are major issues hindering the progress of rechargeable magnesium batteries. Herein, a conjugated, off-planar, two-dimensional (2D) polymer is explored for reversible magnesium storage.
