Energy Storage Systems for Unmanned Underwater Vehicles

open access: yesUnderwater Technology, 2003
The power source of an underwater vehicle is the main component that determines its range of travel and the tasks that it can perform. Until recently, the choice of practical power sources for most applications has been limited to lead―acid and silver―zinc batteries are a well-established technology and are available at low cost. However, they have a
