Abstract:
The invention relates to a method for manufacturing an electrode for an electrochemical energy store, including the following steps: a) providing a base body; b) applying an active material matrix to the base body, the active material matrix including at least one binding agent, if necessary, an active material (1), and a pore forming agent (3), the pore forming agent (3) being soluble in a solvent, in which additional components of the active material matrix are insoluble or are soluble only under certain conditions; c) if necessary, drying the active material matrix; d) rinsing out the pore forming agent (3) by treating the active material matrix with the solvent and e) if necessary, introducing an active material into the produced pores of the active material matrix. Using such a method, a high cycle stability of the electrode may be implemented in a particularly simple and cost-effective way. The invention also relates to a method for manufacturing an electrochemical energy store. The invention further relates to an electrode for an electrochemical energy store and to an electrochemical energy store, such as, in particular, a lithium-ion battery.
