Abstract
A lithium battery includes a positive electrode designed as a hollow cylinder and defines a cavity, a negative electrode arranged in the cavity, a separator, a liquid electrolyte, a first current collector for the negative electrode, a second current collector for the positive electrode, an at least two-part housing that encloses an interior space in which the positive electrode together with the negative electrode arranged in the cavity and the separator are arranged, wherein a pin is provided as a first current collector inside the housing, a part of the housing serves as a second current collector, the pin has a first, terminal section embedded in the negative electrode and in direct contact with the negative electrode, and the pin has a second section not in direct contact with the negative electrode, and an insulator element that protects the second section at least partially against direct contact with the electrolyte.
