Hybrid Battery Component and Method for Producing a Hybrid Battery Component

A hybrid battery component, comprising:

• a plastic housing which is open on both sides and filled with an electrolyte solution;
• an electrode stack arranged in the plastic housing having at least one cathode and at least one anode;
• and
• two covers made of a metallic material, wherein
• a first cover completely covers a first opening, and a second cover completely covers a second opening of the plastic housing in a fluid-tight manner, and
• the at least one anode is electrically conductively connected to the first cover by a first contact element, and the at least one cathode is electrically conductively connected to the second cover by a second contact element.

A method for producing a hybrid battery component, the method comprising the steps of:

• a) providing a plastic housing, which is open on both sides, and two covers of a metallic material, wherein a surface of the covers is at least zonally structured, such that a structured region of the covers incorporates structural elements in a micrometer range and/or in a sub-micrometer range;
• b) arranging a first cover on a first opening of the plastic housing, and permanently fastening the first cover to the plastic housing by introduction of heat;
• c) arranging an electrode stack having at least one cathode and at least one anode in the plastic housing;
• and
• d) subsequently to step c), arranging the second cover on a second opening of the plastic housing, and permanently fastening the second cover to the plastic housing by introduction of heat.
