Safe Designs for Large, High Energy Lithium-ion Cells

TIAX LLC will develop technology to enhance safety and minimize risks from very large lithium-ion cells subject to internal short circuits. Enhanced safety for very large lithium-ion cells, e.g. >100 Ah, is vital for enabling implementation of extremely high energy content lithium-ion batteries, e.g. >1 MWh, both in the military and commercial applications. In Phase I, TIAX will perform a modeling and an engineering assessment for unique large capacity cell designs that are incapable of going into thermal runaway. Also in Phase I, we will demonstrate the feasibility for our approach in proof-of-concept experiments. In Phase II, TIAX will partner with a cell manufacturer to implement and verify the technology in high capacity cells and cell modules.
