Focus of the month: Fire Safety of Stationary Lithium-ion Energy Storage Systems (13)

Technical aspects of the lithium-ion battery security risks (13)

The process leading to the thermal runaway within lithium-ion batteries (13)

Influence of the cell chemistry, age and state of charge on the failure risks (17)

Recent lithium-ion battery fires and their takeaways (19)

As the stationary Li-ion energy storage industry witnesses a remarkable boom, new safety codes and standards try to keep up (22)

As they evolve, Li-ion ESS-related fire codes and standards come with their own set of rules and lead to some confusion within project stakeholders (23)

Recommendations and good practices regarding fire protection and stationary Li-ion ESS (25)

Better be safe than sorry: passive measures for risk prevention (26)

Monitoring measures for early detection (26)

Fire extinction measures (27)

Addendum: Non-exhaustive list of main Lithium-ion ESS fire safety codes & standards (30)
