Cheng‐Che Wu, Yun-Chung Ho, Sheng‐Heng Chung
Abstract
A low-self-discharge lithium–sulfur cell with a carbonized electrospun nanofiber substrate attains a long shelf life and stable electrochemistry with a capacity-fade rate of 0.26% per day and a long cycle life of 200 cycles after resting for 90 days.
