Abstract
The present invention concerns a power supply () comprising a primary cell () adapted to provide a primary cell current. The primary cell () comprises an anode, a cathode current collector and an electrolyte, whereby a passivation layer is formed on a surface of the anode as a result of a chemical reaction between the anode and the electrolyte. To ensure that the passivation layer remains essentially intact for the lifetime of the primary cell, the power supply () further comprises a current limiter () that is configured to prevent the magnitude of the primary cell current exceeding a value that would damage the passivation layer.
