The top-down approach relies on reducing the size of bulk materials to the size of the nanorange of 1–100 nm. This can be done by crushing bulk materials to make powders, sieving to different fractions, further crushing of large size fractions, and finally milling to obtain sizes in the nanorange. Sri Lanka is gifted with very high-purity

Mixed-halogen anti-perovskite-type solid electrolytes Li 2 OHBr 1− x X x (X = Cl, I) are synthesized by room-temperature ball-milling process, and their lattice constants and ionic-conducting properties are investigated. It is suggested that the larger lattice constant provides the higher ionic conductivity, and the highest ionic conductivity of 4.9 × 10 −6 S/cm is achieved in Li 2 OHBr 0
