Custom Lithium Battery Packs & Assemblies

Lithium is the lightest non-gaseous metal, and its negative potential for battery packs is higher than any other metal. Lithium-chemistry batteries and battery packs have the highest specific energy (energy per unit weight) and energy density (energy per unit volume) of all battery types.

While most lithium cells have open circuit voltages (OCVs) between 2.7 and 3.6 V, most lithium primary cells have a relatively high impedance which generally limits them to low-drain applications. Special high-rate discharge cells are available for certain applications.

Lithium primary batteries often have broad operating temperature ranges, and can continue to function properly at temperatures from -55° to 150°C (-67° to 302°F). Though incineration or other exposure to extremely high temperatures can cause lithium batteries to experience catastrophic failure, other battery types typically react similarly in the same conditions.

Primary lithium battery packs are available in several different chemistries, each with its own set of performance and safety characteristics. Poly (carbon monofluoride) lithium, or (CF)X-Li; manganese dioxide lithium, or MnO2Li; thionyl chloride lithium, or SOCl2Li; and sulfur dioxide lithium, or SO2Li, have all proven to be especially popular and effective.

Custom Lithium-Manganese Dioxide Battery Packs & Assemblies

Manganese dioxide lithium cells are similar to poly (carbon mono-fluoride) cells in energy density, construction, safety, and OCV, but generally provide only about half the service life. However, MnO2Li cells are well-suited to applications requiring relatively high continuous- or pulse-current requirements, as their internal impedance is lower than that of other chemistries.
