Electrolyte, method for fabricating electrolyte solution, and lithium ion battery

A method for fabricating an electrolyte solution, comprising:

• providing an organic solution;
• providing a modifier to the organic solution, forming a first mixture solution, wherein the modifier comprises an organic quaternary phosphonium salt and the organic quaternary phosphonium salt is tetrabutylphosphonium hexafluorophosphate;
• providing a clay-containing organic solution and mixing the solution with the first mixture solution, forming a second mixture solution, wherein the clay-containing organic solution comprises inorganic clay and the organic quaternary phosphonium salt is intercalated into the inorganic clay;
• and
• dissolving a lithium salt in the second mixture solution, thereby obtaining the electrolyte solution, wherein the modifier is about 0.05-5 wt % of the electrolyte solution.
