From Fabrication to Failure-Aqueous Processing, Electrolyte Tuning, and Degradation Mechanism Elucidation in Poly(3-Vinyl-N-Methylphenoxazine) Positive Electrodes.

ABSTRACT: Organic electrode materials are considered the next generation of battery electrode materials due to their environmental friendliness, low toxicity, and competitive specific capacities. Herein, a systematic study of the processing of the redox polymer poly(3-vinyl-N-methylphenoxazine) (PVMPO) using water-processable binders, achieving comparable performance comparable to that of PVdF-based electrode, is reported. To address the dissolution of the oxidized polymer into the electrolyte, two different electrolytes are investigated to maximize specific capacity. The use of 1.0 m LiPF₆ in 3:7 EC:EMC electrolyte inhibits the dissolution of the oxidized polymer, as confirmed by UV-Visible spectroscopy, ex situ scanning electron microscopy (SEM) analysis after the 1st charge and 1st dis
