A polymeric separator for an organic electrolyte electrochemical system comprises an elastomeric polymer, optionally, a polymer which swells in the organic electrolyte and with which the elastomeric polymer forms an alloy and, optionally, an inorganic compound. The polymeric separator has a microporous structure characterized by a porosity in the range 30% to 95% and pores with an average diameter in the range 0.1 mum to 5 mum
