Polysulfide dissolution control: the common ion effect

Polysulfide dissolution control: the common ion effect

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 highl...

Zusammenfassung: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.
