The present invention relates to a battery separator, comprising cellulosic fibres of the lyocell genus, wherein the R10-value, the R18-value and the hemicellulose content of the lyocell fibres is as follows: R10 > 83%, preferably > 84% R18 > 93%, preferably > 94% Hemicellulose content < 3%. The present invention furthermore relates to novel lyocell fibres useful for battery separators, as well as batteries comprising the inventive battery separator. |
