Examples
Embodiment 1
[0091]
[0092] Under nitrogen atmosphere, take 0.334g perfluoropinacol in a 50ml round bottom flask, add 1ml tetrahydrofuran solvent; add 1.0mmol dibutylmagnesium heptane solution dropwise to the above solution, and react overnight at room temperature to obtain a white precipitate . Add 0.133g of anhydrous AlCl to the above reaction solution 3 , the solution was stirred overnight and the solution became a homogeneous transparent solution. Above-mentioned reaction solution is spin-dried to obtain white solid and is the magnesium salt of following structure (referring to figure 1 ). The magnesium salt can be directly added with tetrahydrofuran solvent to form an electrolyte solution.
[0093] by structural formula and figure 1 The single crystal picture shows that a tetrahydrofuran molecule in the magnesium salt is coordinated to an aluminum-centered anion, and a stable structure can be obtained.
Embodiment 2
[0095]
[0096] Under a nitrogen atmosphere, take 0.334g of perfluoropinacol in a 50ml round bottom flask, add 1ml of ethylene glycol dimethyl ether solvent; dropwise add 1.0mmol of dibutylmagnesium heptane solution to the above solution, room temperature Reaction overnight resulted in a white precipitate. Add 0.133g of anhydrous AlCl to the above reaction solution 3 , the solution was stirred overnight and the solution became a homogeneous transparent solution. Above-mentioned reaction solution is spin-dried to obtain white solid and is the magnesium salt of following structure (referring to figure 2 ). The magnesium salt can be directly added to the solvent of ethylene glycol dimethyl ether to form an electrolyte.
[0097] by structural formula and figure 2 The single crystal picture shows that one ethylene glycol dimethyl ether molecule in the magnesium salt is coordinated to an anion in the aluminum center, and a stable structure can be obtained.
Embodiment 3
[0099]
[0100] Under a nitrogen atmosphere, take 0.334g perfluoropinacol in a 50ml round bottom flask, add 1ml tetrahydrofuran solvent; slowly add 0.022g Mg(AlH 4 ) 2 Powder, react overnight at room temperature to obtain a white precipitate. The above reaction solution was spin-dried to obtain a white solid which is the magnesium salt with the following structure. The magnesium salt can be directly added with tetrahydrofuran solvent to form an electrolyte solution.
