BATTERY AND SAFETY ARRANGEMENT

The present invention concerns a fire safety arrangement for a battery. More particularly, but not exclusively, this invention concerns a fire safety arrangement for a metal ion battery, for example a lithium ion battery. 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. A fabric band surrounds the housing, such that the fabric band covers the safety valve or vent. This may allow gas to pass through the fabric band, but contain sparks generated by the battery cell within the fabric band.
