1. A primary lithium battery comprising:
- a housing;
a negative electrode comprising a lithium-containing anode active material;
a positive electrode comprising iron disulfide and a binder;
an aluminum positive electrode current collector;
a separator disposed between the negative electrode and the positive electrode and having a thickness of between 12 microns and 37 microns;
an electrolyte including lithium iodide and lithium hexafluorophosphate dissolved in a solvent including an ether; and
a positive lead including aluminum in mechanical contact with the current collector,wherein the battery has an impedance that increases by less than 0.20 Ohms after the battery is dropped six times from a height of one meter onto a hard surface.
