Abstract
In a method for reducing the dendritic metal deposition on an electrode, a non-dendritic state of the metal deposition is ascertained, and a magnetic or electric field is generated at the electrode and is modulated in such a way that it stabilizes the non-dendritic state of the metal deposition. The method is applied, e.g., to a lithium-ion rechargeable battery including an anode having an anode arrester, a cathode having a cathode arrester, and a separator, which are situated in a housing, in which a dendritic metal deposition at the anode is reduced with the aid of the method.

A method for reducing the dendritic metal deposition on an electrode, comprising:
- ascertaining a non-dendritic state of the metal deposition at the electrode;
- generating one of a magnetic or electric field at the electrode;
- and
- modulating the one of the magnetic or electric field to stabilize the non-dendritic state of the metal deposition.
A lithium-ion rechargeable battery, comprising:
- an anode having an anode arrester;
- a cathode having a cathode arrester;
- a separator;
- and
- a housing containing the anode, the cathode and the separator;
- wherein a dendritic metal deposition at the anode is reduced by:
- ascertaining a non-dendritic state of the metal deposition at the electrode;
- generating one of a magnetic or electric field at the electrode;
- and
- modulating the one of the magnetic or electric field to stabilize the non-dendritic state of the metal deposition.
A method for manufacturing a lithium-ion rechargeable battery, comprising:
- ascertaining a non-dendritic state of a metal deposition at an anode;
- and
- generating one of a magnetic field or electric field by a field generating element situated one of on or in the lithium-ion rechargeable battery;
- and
- modulating the one of the magnetic field or the electric field to stabilize the non-dendritic state of the metal deposition at the anode.
