Investigation of thermal runaway propagation in NMC lithium-ion battery stacks using composite materials

Key Points

• Thermal runaway propagates through lithium-ion battery stacks, posing safety risks with NMCs and composites.
• Using composite materials, it was found that the heat generation rate increases by approximately 30% during thermal runaway.
• Analysis of various thermal management strategies indicates mixed results on efficiency and safety measures in battery stacks.
• This study highlights the critical need for enhanced heat management solutions to improve safety in lithium-ion batteries.
