Embodiment 1
[0019] Prepare non-aqueous electrolyte 1M LiPF in an argon-filled glove box (moisture 6 , EC: DMC: EMC=1: 1: 1 (mass ratio), four parts in total, each part of 1L, taking the original sample without additives as the standard, adding hexamethyldisilazane and ethylene oxide respectively in the remaining three samples Tributyl phosphate 0.02%, 0.4%, 1%, after sealing, conduct a comparative test at 50°C to detect the content and color of water and hydrofluoric acid, the results are shown in the table below.
[0020]
[0021]
[0022] It can be seen from the above table that after adding an appropriate amount of hexamethyldisilazane and tributyl phosphite to the non-aqueous electrolyte, the content of water and hydrofluoric acid remains stable and the color is stable compared with the original state without addition.
Embodiment 2
[0024] Prepare non-aqueous electrolyte 1M LiPF in an argon-filled glove box (moisture 6 , EC:DMC:EMC=1:1:1 (mass ratio), a total of three parts, each 1L, with no additives as the standard, the remaining two samples were added 0.5% of hexamethyldisilamine alkane and tributyl phosphite, 0.5% hexaethyldisilazane and triphenyl phosphite, after sealing, conduct a comparative test at 50°C to detect the content and color of moisture and hydrofluoric acid, and the results See the table below.
[0025]
[0026] It can be seen from the above table that after adding an appropriate amount of silicon amine compounds and phosphite compounds to the non-aqueous electrolyte, compared with the original without addition, the content of water and hydrofluoric acid remains stable, and the color is stable.
Embodiment 3
[0028] Prepare non-aqueous electrolyte 1M LiPF in an argon-filled glove box (moisture 6 , EC:DMC:EMC=1:1:1 (mass ratio), a total of six parts, each 1L, with no additives as the standard (three parts), the remaining three samples were added 0.3% Hexa Disilazane and tributyl phosphite, after sealing, conduct a comparative test at 50°C to 70°C to detect the content and color of water and hydrofluoric acid, the results are shown in the table below.
[0029]
[0030] It can be seen from the above table that after adding an appropriate amount of silicon amine compounds and phosphite compounds to the non-aqueous electrolyte, compared with the original solution without adding it, the moisture and The content of hydrofluoric acid remains stable and the color does not change.
