| 摘要 |
The field of the invention relates to a coated method for the preparation of a separator comprising multiple layers of glass or glass and ceramic particles for use in an electrochemical cell, an electrochemical cell comprising such a separator and the use of such an electrochemical cell. The method comprises the steps of providing a mixture of an organic polymeric material, glass or glass and ceramic particles and at least one solvent, and preparing a multilayer by phase inversion. Preferably, the respective ratios of glass and/or ceramic particles, and of organic polymeric material comprise 5 95 %. The ceramic particles may be selected from lithium aluminium titanium phosphate, nano-sized alumina, ZrO2, SiC, LiAlO2, SnO2 or BaTiO3. The separator may be used in an electrochemical cell. |
