1. Field of the Invention
The present invention relates to an electrolytic composition, and more particularly to an electrolytic composition suitable for an antistatic agent, a material used in a battery or in other electrochemical devices, as well as to a non-aqueous electrolytic secondary battery with a high capacity and an excellent cycle stability.

FIG. 2 is a schematic view of a sheet-shaped battery that is employed in an example.
Preferred embodiments of the present invention will be described in detail below.
An electrolytic composition and a non-aqueous electrolytic secondary battery of the present invention achieve reduced interfacial resistance and improved ionic conductivity, presumably because addition of inorganic fine particles to a specific polymer prevents crystallization of the polymer, and a silicon polymer used as the specific polymer has a higher compatibility with inorganic fine particles, particularly with fine silicon particles, than the PEO system has.
In the present invention, if the following requirements are fulfilled, the ion transport number and the ionic conductivity can be enhanced.
