Abstract

FIB-SEM probed the GDL/electrocatalyst/electrolyte interface in Fresh and Used Zn–air batteries. Tomography reveals decompaction, pore formation, catalyst permeation and La segregation, reducing conductivity and O 2 diffusion.

Fields of Study & Subjects

Advanced battery technologies research Electrocatalysts for Energy Conversion CO2 Reduction Techniques and Catalysts
