In Situ Polymer Gel Electrolyte in Boosting Scalable Fibre Lithium Battery Applications

Abstract The poor interfacial stability not only deteriorates fibre lithium-ion batteries (FLBs) performance but also impacts their scalable applications. To efficiently address these challenges, Prof. Huisheng Peng team proposed a generalized channel structures strategy with optimized in situ polymerization technology in their recent study. The resultant FLBs can be woven into different-sized powering textiles, providing a high energy density output of 128 Wh kg -1 and simultaneously demonstrating good durability even under harsh conditions. Such a promising strategy expands the horizon in developing FLB with particular polymer gel electrolytes, and significantly ever-deepening understanding of the scaled wearable energy textile system toward a sustainable future.
