Polysulfide dissolution control: the common ion effect

摘要

A Li-sulfur cell with a high discharge capacity of over 1300 mAh g~(-1) at a C/10 rate, and a controlled overcharge amount less than 1 %, was manufactured by synthesizing a carbon-sulfur nano-composite via a wet milling process, and suppressing polysulfide dissolution using an electrolyte with a highly concentrated lithium salt.
