Across the lithium-ion battery life cycle—from cell manufacturing and pack integration to transport, use, repurposing, recycling and disposal—multiple safety risks can arise, including fire, thermal runaway, toxic emissions and mechanical or electrical hazards. As battery deployment accelerates in mobility and stationary storage, incidents across logistics and end-of-life stages highlight the need for holistic, life-cycle-oriented safety approaches. Current safety knowledge and guidance are often siloed by sector or life-cycle stage, limiting the ability to anticipate risk transfer between stages (e.g., from use to recycling) and to define coherent prevention strategies. In addition, variability in battery designs, ageing states and handling practices increases uncertainty for risk management. This project addresses these gaps by mapping and analysing life-cycle hazards and by developing evidence to support risk assessment, modelling and guidance for safer management of lithium-ion batteries throughout their life cycle.
