The whole picture background is based on the microscopic profile of cathode particles on the current collector. The five magnified cycles represent some common cathode material degradation mechanisms, such as the evolution of oxygen, the dissolution of transition metals (TM), the rupture of CEI films, the cation mixing and the generation of particle cracks.
