A joint development project that included ABB and the Norwegian Defense Research Establishment concluded that a FiFi4Marine (F4M) extinguisher has the best mitigating performance for lithium ion battery fires. The project launched in 2017 to evaluate the performance of fire-extinguishing solutions. F4M’s extinguishing system, a direct injection foam system, had the best heat-mitigating performance. Leadership at the company said their system achieved the maximum scores on all primary objectives.
