Printed microelectrodes for scalable, high-areal-capacity lithium–sulfur batteries†
Abstract
Printed microelectrodes for lithium–sulfur cathodes are produced with aqueous inks and a one-step printing process. The cathodes exhibit high areal capacities of ≥5 mA h cm−2 for 50 cycles and withstand ≥500 cycles. This performance meets energy-storage benchmarks for powering microdevices, and presents a strategic option for future microbatteries.
