Quote from the article:

"Very few researchers study or even teach sulphur chemistry anymore," said Nazar. "It's ironic we had to look so far back in the literature to understand something that may so radically change our future."

I wonder if is there a structured database of scientific material to address such research?

I'm not aware of any structured databases of published research articles, but this project (a database of computed properties for materials) has generated some interesting insights into batteries and other technologies:

For example, check out the papers on phophates as Li-ion cathodes in About->Publications.
