General description

We are committed to bringing you Greener Alternative Products, which belongs to one of the four categories of greener alternatives. Lithium perchlorate (LiClO4) belongs to an Enabling category, and is a sustainable electrolyte salt for lithium-sulfur batteries, inhibiting the polysulfide shuttle and enhancing coulombic efficiency. Its low charge-transfer resistance and protective passivation layer on the lithium anode improve stability and performance, contributing to greener battery technologies.
