The data resources of the electrolyte material research dataset originate from the project titled "Construction and Lithium/Sodium Storage Characteristics of Sn/Sb-based Composite Micro-nano Electrode Materials" (2017YFE0198100). The project leader is Wang Limin. The project undertaker is Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, and the participating units are Changchun University of Science and Technology and Jilin Normal University. The project implementation period ran from August 2019 to July 2022.

This project addresses the key scientific and technical challenges in the application of Sn/Sb-based materials as anodes for Li/Na-ion secondary batteries. Through multi-party Sino-Japanese cooperation, numerous new advancements have been made in the design and fabrication of micro-nano structured and integrated electrodes for Sn/Sb-based materials used in Li/Na-ion secondary batteries, as well as research on novel Sn/Sb-based materials matched with electrolytes and cathode materials.

Regarding electrolyte material research, by regulating the solvation structure of electrolytes to separate anions from Li/Na ions, the occurrence of side reactions is reduced, thereby obtaining high-performance Sn/Sb-based electrode materials with long-cycle stability. Additionally, the dynamic decomposition processes of ester-based and ether-based electrolytes for Li/Na-ion batteries at the electrode interface were investigated. Techniques including sum frequency generation (SFG) spectroscopy were employed to elucidate the formation mechanism and functional role of the solid electrolyte interphase (SEI) film.

The core content of the electrolyte material research dataset consists of data generated from studies on the physicochemical and electrochemical properties of electrolyte materials, including information such as the morphology, phase composition, elemental composition, solvent structure, air stability, and electrochemical performance of the electrolyte materials. The total size of the dataset is approximately 694 MB.
