Saft unveils the world’s only high power ATEX/IECEx certified lithium cells
In addition to offering world-leading performance for intrinsically safe cells, the two new FRIWO cells are currently the world’s only high-power lithium cells rated T4 at +70˚C.
The new FRIWO D-size M20Ex and C-size M52Ex primary lithium cells are designed to meet the growing demand for safe and reliable high-power performance cells for applications in potentially explosive atmospheres. Applications include smart gas meters (including those with built-in GPRS communications), gas or oil tank level monitoring, leak detection, portable gas detectors, pipeline inspection and other applications in the chemical industry such as wireless automation.
The FRIWO D-size M20Ex and C-size M52Ex primary lithium cells provide a high energy density and are certified according to ATEX/IECEx by an independent certification body, which guarantees their full and continued compliance with the IEC 60079-11 standard (Explosive atmospheres – Part 11: Equipment protection by intrinsic safety “I”).
The design of the new Li-MnO2 cells makes them an ideal choice for applications with a low average consumption, but with temporary demands for high current pulses even after long stand-by periods. The C- and D- cells provide capacities of 5.7 Ah and 12.4 Ah respectively, and pulse capabilities of 4 A and 8 A respectively. They also benefit from very low self-discharge rates of less than 1.5 percent in the first year and around 0.5 percent from the second year and can operate over a wide temperature range from – 40°C to + 72°C.
The cells feature a spiral electrode construction for high current and power capability and are housed in stainless steel containers with glass to metal seals, laser welding, safety vent and safety “shut-down” separators. This industrial design ensures a high level of resistance to corrosion and safety under abusive conditions.
