The latent security issue has become the foremost anxiety for lithium-ion batteries (LIBs) wide-ranging of commercialized applications. Hence, the performance of a separator such as chemical durability, electrical insulator, and thermal stability must be superior. Herein, we exhibit a sandwich-structured composite membrane with enhanced thermal resistance and electrolyte affinity, which was prepared by layer-by-layer electrospinning deposition. After 50 cycles, the battery with a 3 wt.% halloysite nanotube electrospinning separator retained 91.80% of its initial discharge capacity, that was a drastic improvement over the commercial polypropylene separator with the numeric of 79.98%. This predominant composite membrane was prepared via an eco-friendly technics and can be thought of an assuring, expectant separator towards high performance lithium-ion batteries.
