Abstract
The front cover artwork is provided by Prof. Chia-Chen Li's group from the Department of Materials and Mineral Resources Engineering, National Taipei University of Technology (Taiwan). The cover picture shows an effective dispersant, poly(4-styrene sulfonic acid) (PSSA), for graphene. The addition of the PSSA-dispersed graphene to a sulfur cathode improves the cell performance of Li–S batteries. Read the full text of the Communication at 10.1002/celc.201801251.
