| description | The invention discloses an electrolyte and a preparation method and application thereof. The electrolyte comprises a solvent, the solvent comprises a fluoro-ether compound, fluoro-carboxylic ester and fluoro-carbonic ester, and based on the total mass of the electrolyte, the mass fraction X of the fluoro-ether compound is 0.1-30%, the mass fraction Y of the fluoro-carboxylic ester is 0.1-60%, and the mass fraction Z of the fluoro-carbonic ester is 0.1-40%. According to the electrolyte, the novel fluorinated solvent is introduced, so that the obtained battery electrolyte not only shows excellent oxidation resistance and high-temperature performance, but also effectively keeps excellent cycle performance, and the performance of a hot box can be improved.
本发明公开了一种电解液及其制备方法与应用。所述电解液包括溶剂，所述溶剂包括氟代醚类化合物、氟代羧酸酯和氟代碳酸酯，其中，基于所述电解液的总质量：所述氟代醚类化合物的质量分数X为0.1-30％，所述氟代羧酸酯的质量分数Y为0.1-60％，所述氟代碳酸酯的质量分数Z为0.1-40％。本发明中电解液通过引入新型氟代溶剂，得到的电池电解液不仅表现优异的耐氧化性能、高温性能，同时有效保持优异的循环性能，并能改善热箱性能。 |
