More particularly, but not exclusively, this invention concerns a fire safety arrangement for a metal ion battery, for example a lithium ion battery cell.A metal ion battery cell comprises a plurality of electrodes and an electrolyte encased within a housing. The housing comprises a safety valve or vent configured to allow gas build up within the housing to vent outside the housing, and a felt filter covering the safety valve or vent, such that gas may pass through the felt filter, but sparks are contained within the felt filter.",
