Abstract

Provided is a separator for use in a rechargeable battery comprising a microporous membrane, wherein the separator maintains porosity after thickness compression during electrochemical cell cycling. Also provided are electrochemical cells with electrodes and a separator, and methods of making a separator and an electrochemical cell. The electrochemical cells comprise a negative electrode having a volume change after lithiation and a separator having a volume change opposite that of the negative elctrode.The separator accommodates the anode volume change by being compressible.
