Researchers have described a new technique to improve chemical stability of electrode materials which can extend the lifespan by employing a very little amount of metals. Using computational chemistry and experimental data, the team observed that local compressive states around the Sr atoms in a perovskite electrode lattice weakened the Sr-O bond strength, which in turn promote strontium segregation.
