COATINGS FOR ELCTROCHEMICAL ELECTRODES AND METHODS OF MAKING THE SAME |
摘要 |
The present invention provides a coating for electrodes for use in electrochemical cells having an electrochemically active species and an electrolyte. The coating includes a selectively permeable material which allows for the diffusion of the active species through the coating during operation of the cell while providing a substantially impervious barrier to the electrolyte. Electrodes utilizing the coatings described herein may be used in primary and secondary cells over a wide range of operating temperatures to delivery better electrochemical performance even at room temperature. Methods of making the coating and an apparatus for performing these methods on a continuous basis are included in the present invention. A novel composition of matter also is contemplated containing lithium, silicon, and fluorine prepared by exposing lithium metal to SiF4. |
