RFI for Lithium-Ion Batteries for Submarines

Indian Navy issued request for information (RFI) on October 28 for development of a 'high-capacity' lithium-ion battery system for refitting to in-service submarines that use lead-acid batteries with in specified a 20-month deadline after the contract is awarded.  A submarine with lithium-ion batteries has greater underwater endurance and can run faster than a comparable ship that has lead-acid batteries.The air-independent propulsion include technologies such as closed-cycle diesel engines that use liquid oxygen and fuel cells, which would function alongside the diesel engines and batteries.
