A multi-functional interlayer for Li–S batteries has been developed to efficiently regulate the shuttle effect and enhance the sulfur utilization using hierarchical Fe₃O₄/C₃N₄ nanostructures.

C₃N₄ nanotube exhibits high surface area and high affinity toward LPS, and the decorating Fe₃O₄ nanospheres on the surface of C₃N₄ nanotube accelerate the adsorption of LPS and improve the electronic pathways.

The combination of Fe₃O₄ nanospheres and C₃N₄ nanotube leads to remarkable battery performance with 400% improvements in specific capacity compared with Li–S battery without using interlayer and a low capacity decay per cycle of 0.02% at 2 C over 1000 cycles.

已经开发出用于Li–S电池的多功能中间层，以使用分层的Fe ₃ O ₄ / C ₃ N ₄纳米结构来有效调节穿梭效应并提高硫的利用率。

Ç ₃ Ñ ₄碳纳米管表现出高的表面面积和朝向LPS高亲和力，并且装饰的Fe ₃ ö _4层C的表面上的纳米球₃ Ñ ₄纳米管加速LPS的吸附和提高电子通路。

与不使用中间层的Li–S电池相比，Fe ₃ O ₄纳米球和C ₃ N ₄纳米管的组合可提供卓越的电池性能，比容量提高400％，并且在1000℃2 C下每循环的容量衰减低至0.02％周期。
