Meaning
Energy storage chemistry providing a stable 3.0 volt output for long-duration industrial sensors. Modern lithium manganese dioxide cells offer high energy density and a low self-discharge rate, making them suitable for devices that must operate for a decade without service.
Discharge Profile
Nominal cell voltage stays relatively stable throughout the entire life of the battery. Devices like smart meters and security sensors rely on lithium manganese dioxide for consistent performance in remote locations. These cells provide reliable power for ten years or more in low-drain applications where frequent battery changes are not feasible.
Thermal Limitation
Operating ranges for these batteries typically span from minus 40 to 85 degrees Celsius. Internal resistance increases as the temperature drops, which can restrict the pulse current available from lithium manganese dioxide in extreme cold. Large capacitors are often placed in parallel with the battery to handle the peak currents required by radio transmissions without triggering a low-voltage shutdown.
Safety Configuration
Hermetically sealed housings and internal pressure vents protect against leakage or rupture during accidental misuse. The solid-state nature of the manganese dioxide cathode improves the safety of lithium manganese dioxide compared to other high-energy chemistries. These cells are frequently selected for consumer products because they do not require complex protection circuits to prevent thermal runaway.
