High-performance pressure-tolerant batteries for deep-dive underwater vehicles move a step closer


Completion of first phase of Steatite-led R&D project sees Li-S cells meeting challenging endurance demands at high pressure and low temperatures 


Steatite has announced the successful completion of the first phase of a 24-month project to develop a pressure-tolerant lithium sulphur (Li-S) battery pack that can improve the endurance and speed of ‘deep-dive’ autonomous underwater vehicles (AUVs). Having demonstrated that Li-S cells can meet the demanding challenge of operating at depths up to 6000m, the project can now move on to the battery development phase involving continued development of Steatite’s pressure-tolerant multi-chemistry Battery Management System (BMS).

The MAS (Marine Autonomous Systems) Consortium is a group of UK companies and academic partners led by Steatite and funded by Innovate UK and the Defence Science and Technology Laboratory (Dstl). The project, which is due for completion in October 2017, aims to exploit the potential of Li-S cell technology to surpass conventional lithium-ion (Li-ion) solutions, and will enhance the capabilities of the scientific and defence vehicles used in applications across the marine and maritime community, including subsea structures, ROVs, profilers, buoys and submersible systems.
