Method for producing porous electrodes for electrochemical cells |
| abstract |
The invention relates to a method for producing an electrochemical cell comprising at least one porous electrode (2'), the method comprising at least the following method steps: (a) providing an electrode composition in the form of a homogeneous mixture comprising (i) at least one particulate active material (3); (ii) at least one particulate binder (5); (iii) at least one particulate pore-forming agent (4); and (iv) optionally at least one conducting additive (6); (b) forming a mouldable mass from the electrode composition; (c) applying the electrode composition to at least one surface of a substrate (1) to obtain a compact electrode (2); (d) producing an electrochemical cell comprising at least one compact electrode (2) which comprises the electrode composition according to method step (a); and (e) heating the at least one compact electrode (2) to liquefy the at least one particulate pore-forming agent (4); and/or (f) bringing the compact electrode (2) into contact with at least one liquid electrolyte composition or at least one liquid constituent of an electrolyte composition for an electrochemical cell which is capable of at least partially dissolving the at least one particulate pore-forming agent (4) to obtain a porous electrode (2'), wherein method steps (a), (b), (c), (d) and (e) are carried out substantially without solvents. |
