Batteries play a vital role in both nuclear and conventional submarines (with or without air-independent propulsion (AIP): their performance is a crucial factor in determining the length and nature of any mission.
Li-ion – the battery technology of the future
Li-ion is the future of battery power in submarines. It can enhance on-board efficiency while providing reliable energy storage for essential back-up services.
The main advantages of Li-ion batteries include:
- improved autonomy
- greater reliability
- longer sustained performance at speed
- small size
- high capacity
- long life and low lifecycle costs
- enhanced stealth characteristics
Li-ion batteries are also ideal to act as buffer batteries in AIP systems, and for delocalized power for actuators.
