| titleOfInvention | Lithium ion battery is with multi-functional two-sided heterogeneous Janus diaphragm |
| abstract | Disclosed herein is a multifunctional double-sided heterogeneous Janus separator for a lithium ion battery. The double-sided heterogeneous Janus diaphragm is formed by compounding a polyolefin single-sided inorganic coating diaphragm layer, a bonding layer and a high-temperature-resistant polymer nanofiber film layer which are sequentially arranged, wherein the bonding layer and the nanofiber film layer are positioned on one side of the polyolefin diaphragm, which is not an inorganic coating; the thickness of the polyolefin single-sided inorganic coating diaphragm is 4-25 mu m; the thickness of the high-temperature resistant polymer nanofiber membrane is 0.4-11 mu m; the thickness of the bonding layer is 0.4-4 μm; the total thickness of the Janus diaphragm is 5-40 mu m. In the composite diaphragm, the inorganic coating can improve the whole lithium dendrite puncture resistance of the diaphragm, the nanofiber layer provides high-temperature dimensional stability and high liquid retention property, and the polyolefin diaphragm can play a hole closing role at high temperature to block lithium ion transmission. The utility model discloses process is simple and easy, and bonding strength is high between nanofiber layer and the polyolefin diaphragm layer, and thermal dimension stability and electrolyte infiltration nature are excellent, and application prospect is good. |
