| abstract | The invention provides an electrolyte, which comprises carboxylic ester and halogenated methane. The carboxylic ester can be combined with cations of the electrolyte, and the halogenated alkane has small volume and can play a role of a lubricant to reduce the ion migration resistance, so that the ion conductivity of the electrolyte is improved; the sylvite additive can change the solvation condition of electrolyte cations in the electrolyte and the film forming reaction form of an electrode interface, so that a thin and stable SEI film can be formed on the surface of the negative electrode, and the resistance of ions embedded into the negative electrode is reduced; AgPF 6 The additive can be reduced on the surface of the negative electrode to form nano Ag particles, so that the charge transfer resistance of the SEI film is reduced, and the ion embedding/de-embedding resistance is reduced; through the combined action of the carboxylic ester, the halogenated methane, the electrolyte and the additive, the discharge performance and the cycle performance of the battery below minus 40 ℃ are improved, and the battery can still discharge in a deep low-temperature environment at minus 70 ℃. The invention also provides a preparation method of the electrolyte and a battery containing the electrolyte. |
