LITHIUM primary batteries
The primary (non-rechargeable) battery was the first method of domesticating electricity. The simple placing in contact of different materials in the presence of an electrolyte creates a potential difference and hence an electric current.
Various electrochemical pairs currently cohabit. Those based on lithium can claim a high energy density as well as a very low auto-discharge rate.
Li-SOCl2 (Lithium-Thionyl Chloride)High energy, high voltage, long life and high temperature range. |

Li-SO2 (Lithium-Sulphur Dioxide)High power, excellent behaviour in cold environments. |
||
Li-MnO2 (Lithium-Manganese Dioxide)High power and high energy without passivation. |
