Naval Group Launches LIBRT

Naval Group said it has developed a high performance and highly secure Li-ion batteries system to provide its conventional submarines with improved operational capabilities, as well as an immersion period and reloading time largely optimized.

"The navies that will operate this new technology will boast a major technological superiority on theaters of operations," the company said.

This project involved close cooperation between Naval Group, Saft, CEA Tech and EDF R&D.

The Li-ion batteries system LIBRT, improved security and performances on board submarines developed by Naval Group LIBRT increases significantly the submarines’ submerged endurance and improves its stealth, while guaranteeing better security conditions.

This cutting-edge technology offers twice more available energy while reducing the reloading time.

In hostile environments, the submarine will therefore take advantage from an increased submerged operating range as well as from the capability to evade all kinds of naval threats. Fast loading battery limits the time spent in periscopic immersion, thus enhancing the indetectability of the submarine. These are valuable operational advantages that provide the submarines with a real technological superiority compared to current generations. As for security, nothing has been left to chance. To fit a batteries system on-board a submarine requires upstream precautions to ensure complete security. These requirements have been integrated from the earliest stage of the design of this new batteries system, being for the choice of electrochemistry or for the conception of the embedded system.

To do so, Naval Group has implemented the same methodologies and security requirements as for the conception of nuclear submarines for the French Navy.

This is a tight-knit and fully dedicated French Team that is mobilized over the development and the implementation of this new batteries system.

Naval Group brings its experience as a system provider and integrator, Saft its expertise in the conception and production of state-of-the-art Li-ion batteries, CEA Tech provides Naval Group with its research capacities in the fields of chemistry, structure and electronics and, finally, EDF R&D volunteers its experience and its first rank testing facilities for energy production systems requiring high levels of safety, reliability and security.
