Method for reducing self discharge in an electrochemical cell |
摘要 |
A method for reducing the self discharge rate and the variability in the self discharge rate of an electrochemical cell wherein a porous separator is inserted between a cathode and an anode of the cell and the porous separator contains a nanoweb that comprises a plurality of nanofibers that may contain a fully aromatic polyimide and the fully aromatic polyimide has a degree of imidization of greater than 0.51 where degree of imidization is the ratio of the height of the imide C—N absorbance at 1375 cm−1 to the C—H absorbance at 1500 cm−1. |
