{"product_id":"clsbcsspn","title":"Polymeric Sulfur\/Sulfurized Polyacrylonitrile Composite (SSPN) Powder for Li-S Battery Cathode, 20-100 g\/bottle, CLSBCSSPN","description":"\u003cp\u003eSulfurized Polyacrylonitrile (SPAN) has long been a premier solution to these issues because it chemically binds sulfur to a conductive, conjugated carbon framework. However, SPAN typically maxes out at a sulfur content of roughly 40–50 wt%. To push the energy density boundary further, researchers developed Polymeric Sulfur\/Sulfurized Polyacrylonitrile Composites (SSPN). This strategy incorporates structural polymeric sulfur stabilized inside or hybridized with a highly sulfurized PAN matrix, combining high sulfur loading with the exceptional cycling stability of chemically bound sulfur.\u003c\/p\u003e\n\u003cp\u003eIn an SSPN composite, the synthesis parameters (such as altered S:PAN precursor ratios, lower-temperature stabilization zones, or mechanical shearing) are tuned to induce the formation of polymeric sulfur. Polymeric sulfur consists of long, linear catenated sulfur chains rather than isolated, cyclical S8 rings. When hybridized with the dehydrogenated PAN network, these long polymeric chains are sterically confined and physically\/chemically stabilized by the surrounding highly sulfurized heterocyclic ladder polymers.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%;
