Batteries can pose significant hazards, such as gas releases, fires and explosions, which can harm users and possibly damage property. This blog explores potential hazards associated with batteries, how an incident may arise, and how to mitigate risks to protect users and the environment.
Legal regime The UK already has legislation in place dealing with fire and safety risks such as those posed by batteries. For example, the Health and Safety at Work etc Act 1974 (‘the 1974 Act’) requires employers to ensure the safety of their workers and others in so far as is reasonably practicable.
To reduce the safety risk associated with large battery systems, it is imperative to consider and test the safety at all levels, from the cell level through module and battery level and all the way to the system level, to ensure that all the safety controls of the system work as expected.
The review also highlights the two most promising future research directions in the field of battery safety: (1) aqueous batteries with expanded electrochemical window of stability, (2) all solid state batteries with low interfacial impedances.
