Abstract
A method is provide for manufacturing a lithium anode and to a lithium anode for a lithium cell and/or a lithium battery. In order to improve the service life, performance capability and safety of a lithium cell and/or a lithium battery equipped with the lithium anode, the lithium anode includes a surface-structured current conductor and/or a surface-structured protective layer having at least one surface section circumscribed by a raised surface section, the surface structuring/structurings forming at least one cavity, and the at least one cavity being, in particular electrochemically, filled with anode active material. Also provided are a lithium cell and a lithium battery equipped with a lithium anode.
Claims19
A method for manufacturing a lithium anode for at least one of a lithium cell and a lithium battery, comprising:
- providing a current conductor and a protective layer, at least one of the current conductor and the protective layer having a surface structuring, in which at least one raised surface section circumscribes at least one lower-lying surface section;
- placing the current conductor and the protective layer against each other, the surface structuring forming at least one cavity;
- and
- electrochemically filling the at least one cavity with anode active material.
A lithium anode for at least one of a lithium cell and a lithium battery, manufactured using a method for manufacturing, comprising:
- providing a current conductor and a protective layer, at least one of the current conductor and the protective layer having a surface structuring, in which at least one raised surface section circumscribes at least one lower-lying surface section;
- placing the current conductor and the protective layer against each other, the surface structuring forming at least one cavity;
- and
- electrochemically filling the at least one cavity with anode active material.
A lithium anode for at least one of a lithium cell and a lithium battery, comprising:
- a current conductor;
- and
- a surface-structured protective layer having at least one surface section circumscribed by a raised surface section, wherein:
- the current conductor and the protective layer abut against each other,
- the surface structuring of the protective layer forming at least one cavity, and
- the at least one cavity is filled with anode active material.
A device including at least one of a lithium cell and a lithium battery, the device including at least one lithium anode, comprising:
- a current conductor;
- and
- a surface-structured protective layer having at least one surface section circumscribed by a raised surface section, wherein:
- the current conductor and the protective layer abut against each other,
- the surface structuring of the protective layer forming at least one cavity, and the at least one cavity is filled with anode active material.
