Abstract

TIAX LLC is proposing to demonstrate technology for early detection of incipient internal short circuits in lithium-ion cells for three battery systems of interest to the Navy. In the Phase II Program, we will demonstrate function of two distinct short circuit detection technologies in relevant subscale battery packs, characterize design trade-offs between these technologies as a function of different types of battery pack, and demonstrate readiness for implementation in Navy systems. In the Phase II Option, and in consultation with the Navy, one of the battery systems will be selected and modified with internal short circuit detection technology designed in Phase II. The standalone battery, equipped with embedded prototype internal short circuit detection technology, will be delivered to the Navy.
