Capable of Operating at +125°C

01.12.2007 (wattgehtab.com) - Saft has launched the world's first Li-ion (lithium-ion) cell capable of operating at temperatures of up to +125°C - an innovation that opens up exciting new possibilities for the design of MWD (Measurement While Drilling) tools. At the same time, Saft has also launched a new D-size primary lithium cell.

The launch of the new VL 25500-125 Li-ion cell and the new LSH 20-150 primary cell is a major development in the design of reliable, cost-effective power sources for electronic equipment operating under the high levels of shock, vibration and pressure and extreme temperatures experienced by MWD tools in the oil and gas exploration industry.

Li-ion opens up new horizons for MWD design
Saft has achieved a world first by creating a robust Li-ion cell capable of charging and discharging at extreme temperatures up to +125°C, while being able to safely withstand temperatures up to +135°C. This major leap in operating temperature, from the current maximum of +65°C, opens up new horizons for MWD tool developers and manufacturers as, for the very first time, they will be able to incorporate a high performance rechargeable battery in their design. In some future applications this could eliminate completely the need to withdraw an MWD tool for replacement of a spent battery, with the benefit of improved continuity for the drilling operation.
