Stanford researchers have developed a portable sensor device for rapid detection of heavy metal ions using a sulfidation process and concentrator for increased visual detection.
Researchers in Stanford's Yi Cui Lab have developed an ultra-light, fire-retardant battery current collector. Commercial Cu-Al current collectors account for 15-50 wt.% of the total battery weight – dead weight that dramatically limits battery density.
Researchers in the Cui lab have designed a polymer-polymer solid-state electrolyte for lithium batteries that is fireproof, lightweight, and mechanically robust.
