Primer for electrochemical cell, especially lithium, lithium ion or lithium ion-polymer cell or supercapacitor, has binder of metal borosilicate, preferably lithium borosilicate

摘要

Primer for electrochemical cell has a binder of metal borosilicate (I). Primer for electrochemical cell has a binder of borosilicate of formula (I): MwBxSiyOz (I); M : a metal; w, x, y, z : more than 0 . Independent claims are also included for the following: (1) electrochemical cells with a cathode and an anode, in which the collectors for the cathode and/or cathode are completely or partly covered with a layer of this primer; (2) preparation of the primer.
