In Batteria Electrochemical Polymerization to Form a Protective Conducting Layer on Se/C Cathodes for High‐Performance Li–Se Batteries

The lithium–selenium (Li–Se) battery is a promising energy storage system for portable devices owing to its high energy density (2528 Wh L −1 ) and electrical conductivity (10 −3 S m −1 ). The main issue with Li–Se batteries is their poor stability originating from the dissolution of Se‐containing compounds. Hence, many studies have focused on the immobilization of Se using protective layers prepared via ex situ or in situ approaches. However,...
