(JP10334877-A)      The fabrication of a porous composite separator for an electrochemical cell including an electrode comprises disposing a solution of separator precursor on the electrode and transforming the solution to form a porous composite separator that adheres to the electrode. The solution comprises a solid particulate material and a polymer binder having a ratio of binder to particulate material of 5/95 to 50/50. Also claimed are an electrochemical cell comprising a layer of porous composite separator material disposed on a first layer of electrode material, where the separator material, having micropores and comprising a composite structure comprised of the binder and solid particulate, adheres to the first layer of electrode material; (b) a second layer of electrode material superjacent to th porous composite layer; and (c) a liquid electrolyte contained within the pores of the porous composite separator so that the electrolyte provides a conducting medium between the first and second layers. A process for forming a microporous separator for an electrochemical cell including an electrode comprising printing a continuous layer of the separator on the electrode by disposing a solution comprising the above solid particulate material and curing the layer to form micropores within. An electrochemical cell having a liquid-electrolyte-permeable separator comprising an electrode, a matrix of solid particulate material, directly bonded on electrode, which is so thin that it would not be self-supporting and sufficient binder to hold the material in an open matrix which permits liquid electrolyte to permeate the layer of solid particulate material.    USE -   For microelectronics in manufacture of electrochemical power supplies of high energy and power density for portable electronic devices, e.g. portable computers, telephones, audio, video devices, pacemakers.    ADVANTAGE -   Small and improved quality.
