Nanomaterial Extends Lithium-Sulfur Battery Life (image) DOE/Pacific Northwest National Laboratory Share Print E-Mail Caption Pacific Northwest National Laboratory developed a nickel-based metal organic framework, shown here in an illustration, to hold onto polysulfide molecules in the cathodes of lithium-sulfur batteries and extend the batteries' lifespans. The colored spheres in this image represent the 3D material's tiny pores into with the polysulfides become trapped.
