中文摘要:

Murdochite 类型 Ni 6 MnO 8 在碳布(NMO-SA/CC ) 上种的三维的 mesoporous nanosheet 数组被综合使用一在原处生长策略。作为 self-supported 为解放的没有文件夹的阳极, NMO-SA/CC 层次 nanostructures 展览超离频能力,优秀骑车稳定性,和好率能力。优秀的锂存储表演能被归功于到在 NMO-SA 和 CC 之间的完美的电的接触。在薄 nanosheet 的 mesopores 能由减少与电解质最大化电极接触李 + 散开路径。而且,这些效果减轻在李 + intercalation/deintercalation 周期期间从大体积变化发源的弄成粉和凝块。在原处,在起始的 lithiation/delithiation 过程期间记录的 X 光检查吸收罚款结构(XAFS ) 光谱揭示变换反应过程。

英文摘要:

Murdochite-type Ni6MnO8 three-dimensional mesoporous nanosheet arrays grown on carbon cloth (NMO-SA/CC) are synthesized using an in-situ growth strategy. As self-supported binder-free anodes for LIBs, the NMO-SA/CC hierarchical nanostructures exhibit ultrahigh capacity, excellent cycling stability, and good rate capability. The excellent lithium storage performance can be ascribed to the perfect electrical contact between NMO-SA and CC. The mesopores in the thin nanosheet can maximize the electrode contact with the electrolyte by decreasing the Li+ diffusion path. Moreover, these effects relieve the pulverization and agglomeration that originate from the large volume variations during the Li+ intercalation/deintercalation cycles. The in-situ X-ray absorption fine structure (XAFS) spectrum recorded during the initial lithiation/delithiation processes reveals the conversion reaction process.
