An in-situ strategy to synthesize ultrathin two-dimensional MXene-TiN heterostructures and the ultrathin structure extremely shortens the electrons diffusion distance from catalysts to active sulfur species.
The heterostructure exhibits superior electronic structures to strongly capture the polysulfides and enhance bidirectional electrocatalytic ability between LiPSs and Li₂S.
The advanced cathode achieves an excellent long-term cyclability with an extremely low-capacity fading rate of 0.022% over 1000 cycles and a remarkable areal capacity of 8.27 mAh cm⁻² at high sulfur loading of 10.16 mg cm⁻².

超薄层状 MXene-TiN 异质结构的构建使高面积容量锂硫电池具有良好的催化能力

原位合成超薄二维 MXene-TiN 异质结构和超薄结构的策略极大地缩短了从催化剂到活性硫物种的电子扩散距离。
异质结构表现出优异的电子结构，可以强烈捕获多硫化物并增强 LiPS 和 Li ₂ S之间的双向电催化能力。
先进的正极实现了出色的长期循环性能，在 1000 次循环中容量衰减率极低，仅为 0.022%，在 10.16 mg cm -2 的高硫负载下，面积容量为 8.27 ^mAh cm ^-2。
