Slow news days around here so I thought I would post this. The new process is cheaper also.

It turns out, a new element added to the experimental battery acted as an ionic conductor, causing the antimony sulfide in the experiment to separate.

It turned out the battery was performing electrolysis, and the metal it was producing was 99.9 percent pure. That got the researcher's attention -- traditional smelting produces large quantities of greenhouse gas, and is a significant contributor of air pollutants. Sadoway's accidental smelting process produced almost none.
