| 英文摘要 | Lithium-ion batteries are receiving intensive interest due to their promising prospect for electric vehicles. However, the safety issues and low rate capability of lithium-ion batteries limited their further development due to the poor dimensional thermo-stability and low electrolyte wettability of commercial polyolefin separators. Herein, we report a sponge-like porous poly (ether-ether-ketone) (PEEK) membrane with super high thermal stability and good rate capability for lithium ion batteries. The porous PEEK membrane showed no fusion deformation even at temperature of 350 degrees C, showing excellent thermal stability. An electrolyte uptake of 251% was obtained for a porous PEEK membrane, which was more than twice than that of a commercial PE separator, showing very good electrolyte wettability. As a result, the lithium-ion battery with a porous PEEK membrane showed a discharge capacity of 124.1 mA h g(-1) at 5 C, showing good rate performance. The battery performance of a PEEK membrane after treating at 350 degrees C changed rarely. The PEEK membranes provide more options for cost-effective high power battery separators. |
