The lithium in your Volt batteries may have been ejected from a black hole. The spectra of the most ancient and pristine stars in our galaxy reveal abundances of the isotope lithium-7.7There has been a lingering question concerning the source of the lithium as well as the amount. Now researches have theorized that hundreds of thousands of black holes in our galaxy may produce substantial amounts of lithium-7. Matter surrounding some black holes may be hot enough to generate the lithium by nuclear fusion of pairs of helium nuclei, which could generate lithium.
While there are mysteries surrounding the amount of lithium in the universe, there is no mystery about the tremendous amount of fun there is driving a Chevy Volt.
Naturally occurring lithium is composed of two stable isotopes, lithium-6 (~92.5%) and lithium-7 (~7.5%).
