New additions to next-gen Thionyl Chloride battery family

01 March 2022

Ultralife Corporation has extended its ER Generation X family of Lithium Thionyl Chloride (LiSOCl2) batteries for critical applications, with two new products added to the range of rugged, energy-dense batteries.

The new additions are the low-rate UHE-ER14250-X 1/2AA-size bobbin cell for asset tracking and more, plus the high-rate UHR-ER18505-X A-size spiral cell for higher-power applications (such as radio communications and cellular transmission).

The new ER Generation X batteries offer among the highest energy densities available on the market, 432 and 313 Watt-hours per kilogram (Whr/Kg) respectively, owing to their LiSOCl2 chemistry. Each product in the range also boasts a self-discharge rate of less than two per cent each year (in storage) and delivers a stable discharge voltage in temperatures spanning from -55 to +85 degrees Celsius.

Drawing on Ultralife Corporation’s experience in serving mission-critical applications in demanding sectors, the extended temperature range of the batteries is complemented by a robust hermetically sealed exterior. This is particularly crucial as non-rechargeable batteries, like these, are often left in remote or hard-to-access locations where charging would be impractical or impossible (such as on a mountaintop in a climate monitoring device or at sea in offshore instrumentation equipment and sonobuoys).

“Since its launch, the ER Generation X range has proven popular due to its reliable performance and versatility,” explained Eric Lind, Vice President of Commercial Operations and Business Development at Ultralife Corporation. “The latest additions provide even more options to support engineers working on the next generation of devices.

“For example, the A-size cell is an ideal option for larger instrumentation applications that must be able to support real-time, high-frequency communications. The 1/2AA0size is ideal for devices that must be discrete, like asset trackers, due to its compact height of 25mm max. and 14.5mm max. diameter.”

Ultralife’s full range of ER Generation X batteries and other products are available globally. In Europe, design engineers and OEMs can contact Accutronics, an Ultralife company, on +44 (0)1782 566 622 to discuss how the new products can support their projects.
