One of the major issues hobbling the commercialization of high energy-density lithium-sulfur batteries is the “polysulfide shuttle”—the shuttling of polysulfide ions between the cathode and anode.

One of the most significant impediments to an increased market share for plug-in vehicles is the high cost of rechargeable energy storage. This can represent a very significant cost element of a typical battery electric vehicle (BEV); manufacturers need to strike a balance between product affordability and available range between recharges.

Lithium-sulfur (Li-S) batteries are one of the most attractive candidates for the next generation of high-energy rechargeable Li batteries because of their high specific energy at a working voltage of ca. Capacity remains at 85% of the initial value over the 25 first charge/discharge cycles. 2017.04.088.

Sulfur, a light and abundant element capable of gaining multiple electrons, is a promising alternative cathode material for high-energy-density rechargeable batteries (i.e., Brudvig, and Hailiang Wang (2017) “Ultrathin dendrimer–graphene oxide composite film for stable cycling lithium–sulfur batteries” PNAS doi: 10.1073/pnas.1620809114.

Currently, most studies use a high electrolyte amount with an electrolyte to sulfur (E/S) ratio in the range of 10 -50 mL E /g S (flooded electrolyte condition). There have been very few reports on rechargeable Li-S batteries using a low electrolyte amount with an an E/S ratio less than 5 mL E /g S (lean electrolyte condition).

Polysulfide-Blocking Polymer Membrane Separators for Rechargeable Lithium-Sulfur Batteries The advanced energy economy will be a dominant market force in the 21st century, one driven by US demand but asymmetrically low domestic supply without immediate action. This has the potential to displace over 4.2 Sepion Technologies.
