New FRIWO D-cell M20EX for potentially explosive applications |
|
|
Büdingen, November 8th, 2010
The new FRIWO M20EX lithium manganese dioxide (LiMnO2) cell has been developed to offer a unique, world leading level of high performance for an intrinsically safe D-size cell intended for industrial applications requiring high power under potentially explosive applications, especially smart gas meters with built-in GPRS communications as well as a wide variety of other uses such as gas tank level monitors, leak detectors, petrochemical facilities and mining applications.
The FRIWO M20EX cell has been designed in compliance with the IEC 60079-11 standard (Explosive atmospheres - Part 11: Equipment protection by intrinsic safety "I"). With a T4 rating at +70°C, a nominal capacity of 12.4 Ah (at +20°C, under a 150mA discharge) and a pulse capability up to 8A, the FRIWO M20EX has established a unique position as an intrinsically safe primary lithium cell with high power capability. It also offers the benefits of a low self-discharge rate - less than 1% per year of storage at +20°C - and the capability to operate over a wide temperature range (-40°C to +70°C).
The FRIWO M20EX cell is based on a spiral electrode construction for high pulse applications and has an industrial design housed in a stainless steel container, with glass to metal seal, laser welding, safety vent for long shelf life and offers a high level of resistance to corrosion and safety under abusive conditions.

Büdingen, May 17th, 2010
Friemann & Wolf Batterietechnik GmbH (FRIWO) powered the successfull MIPAS balloon campaign of the IMK-ASF (Institute for Meteorology and Climate Research in Karlsruhe, Germany) on its launch on 24. January 2010 in Kiruna, Sweden.
Particular focus of the activities of IMK-ASF is to investigate the complex links and feedbacks between climatic change, dynamics and transport, and atmospheric chemistry.
The IMK-ASF uses for the MIPAS balloon campaigns a parallel configuration of 10 powerfull MIRA batteries, each equipped with 10 FRIWO M24HR - DD cells in series, which enables an absolutely safe power supply at extremely low temperatures in the stratosphere.
The next MIPAS balloon campaign of IMK-ASF is planned for early 2011.
Please find more details about the MIPAS balloon campaign under the following links:

All FRIWO LiMnO2 batteries are now also available in antimagnetic versions |

Büdingen, January 14th, 2010
Friemann & Wolf Batterietechnik GmbH, manufacturer of high-performance LiMnO2 primary batteries, is now offering all cells from its product range in antimagnetic versions.
This opens up opportunities for new civilian and military applications. For example, for the first time it is now possible to use these batteries in areas of healthcare where high magnetic fields currently prevent the deployment of standard batteries, such as near NMR/CAT - scanners.
The measured magnetic value of these new batteries is typically over 50 per cent lower than 5 nT (nano Tesla), which is defined as the maximum value for the magnetic signature (according to STANAG 2987).
The new antimagnetic cells are available in the sizes 2/3 sub-C to DD.
