Abstract

We demonstrate here the feasibility of valence mapping of particulate samples, and discuss the factors that limit quantitative data extraction from the maps. Three manganese oxide powder samples were characterized: a commercially obtained Mn2O3 powder; and two chemically synthesized cryptomelane K{Δ, Δ}MnO2 battery materials, one with 50 nm to 100nm grains,and one with 5nm x 10nm to 30nm rods.
