Deskripsi

Polymer binders in battery electrodes can affect their performance, however design rules are still lacking. Here, the authors reveal why polyelectrolyte binders outperform charge-neutral alternatives in lithium–sulfur batteries, showing how cationic polyelectrolytes can regulate ion transport selectively.
