Layered perovskite battery structure

Ruddlesden-Popper phase

Ruddlesden-Popper (RP) phases are a type of perovskite structure that consists of two-dimensional perovskite-like slabs interleaved with cations.The general formula of an RP phase is A n+1 B n X 3n+1, where A and B are cations, X is an anion (e.g., oxygen), and n is the number of octahedral layers in the perovskite-like stack. [1] Generally, it has a …
