Abstract: A method for modifying an electrochemical cell includes: providing an electrochemical cell including a cathode, an anode, and a layer disposed therebetween, particularly a separator or a polymer electrolyte; effecting at least one charge and discharge sequence on the electro-chemical cell; detecting damage or defect to a first material of a cell component subjected to the at least one first charge and discharge cycle; removing at least portions of the damaged or defective first material from the cell component, whereby at least one cell component is obtained having a first area including the first material and a second area from which damaged or defective first material has been removed; and introducing a second material into the second area formed in the cell component.

Abstract: The invention relates to a facility (10, 20) operating according to galvanic principles such as particularly a battery, respectively an accumulator, in particular a lithium-ion battery, and assemblies thereof. The facility comprises a housing (12), at least one first current conductor (14), which protrudes from the housing (12), and at least one first heat conducting facility (24), which is connected to the first current conductor (14) in heat flow communication, and which is developed such to conduct thermal energy from the first current conductor (14).
