DICP Binder Paper Published in Advanced Functional Materials

DICP Sustainability flowchart

Congratulations to Zhimeng Liu and coauthors on the recent publication of their article "Reversible Crosslinked Polymer Binder for Recyclable Lithium Sulfur Batteries with High Performance" in Advanced Functional Materials! This paper details a novel Li-S binder system consisting of commercially-available poly(acrylic acid) and poly(ethyleneimine), which react to form a dissolvable ionic crosslinked polymer (DICP) network. Not only does this binder lend improved cycling performance to sulfur/carbon composite cathodes, but it readily dissolves under basic aqeuous conditions, paving the way for easy recycling of used Li-S cells.
