A new battery leveraging lithium iron phosphate (LFP) chemistry and delivering 80 kWh of energy storage for marine electric drives was unveiled at the Electric & Hybrid Marine World Expo in Amsterdam, Netherlands, by Torqeedo GmbH.

The Deep Blue Battery 80 offers twice the capacity of the previous generation of Deep Blue batteries and aSource: Torqeedo GmbHSource: Torqeedo GmbH high volumetric energy density of 278 Wh/l to support larger, heavier displacement vessels such as cruising yachts and commercial vessels. The cell-to-pack architecture represents an advanced approach to battery assembly in which individual battery cells are directly integrated into the module without the need for intermediate modules or components.

The design offsets the lower energy density typical of LFP batteries and enables a more compact footprint that is easier to install in many boats. In addition to longevity and safety benefits, these batteries are assembled with abundant raw materials, which avoids environmental costs and sourcing instability of critical metals in current power module markets.
