Combined In Situ EQCM-Raman Study of Zn Storage Mechanism in Polyaniline for Zinc-Ion Battery.

ABSTRACT: Zinc-ion batteries (ZIBs) have attracted increasing attention as safe, cost-effective, and environmentally friendly alternatives to lithium-ion batteries for large-scale energy storage. Among various cathode materials for Zn batteries, polyaniline (PANI) is a potential material that presents benefits such as high conductivity and pseudocapacitive behavior. However, it often suffers from limited cycling stability and structural degradation during repeated charge-discharge processes. Here, in situ electrochemical quartz crystal microbalance (EQCM)-Raman technique is combined to understand the Zn storage behavior in PANI wherein limited Zn insertion is observed along with detachment of the polymer from the substrate. Through anion doping of PANI, the structural stability is enhanced, and the
