A mild process for the synthesis of Na2Ti3O7 as an anode material for sodium-ion batteries in deep eutectic solvent

Autor: Yanxuan Wen, Zongni Chen, Cheng Wang, Jing Su, Yang Yang, Cui He

Publikováno v: Journal of Materials Science: Materials in Electronics. 30:8422-8427

Low capacity and poor cycle stability are two typical drawbacks of Na2Ti3O7 when applied to the sodium-ion batteries as electrode materials. Here, we successfully synthesized Na2Ti3O7 by a mild process in chloride/ethylene glycol-based deep eutectic

Proton solvent-controllable synthesis of manganese oxalate anode material for lithium-ion batteries

Autor: Ya-Nan Zhang, Jing Su, Hong-Xiang Kuai, Yanxuan Wen, Yun-Fei Long, Shu-Shu Li, Xiao-Yan Lv

Publikováno v: RSC advances. 11(38)

Manganese oxalates with different structures and morphologies were prepared by the precipitation method in a mixture of dimethyl sulfoxide (DMSO) and proton solvents. The proton solvents play a key role in determining the structures and morphologies
