| titleOfInvention | A kind of battery separator and its preparation method and lithium ion battery |
| abstract | The invention discloses a battery separator, a preparation method thereof, and a lithium ion battery. The raw materials for preparing the battery separator include 30-50% binder, 5-10% nanocellulose, 30-50% inorganic solid state in terms of mass percentage. Electrolyte and 15-30% closed cell material. Among them, the use of nanocellulose as the skeleton of the separator can achieve self-support, and the addition of inorganic solid electrolytes can effectively improve the ion transport force and heat resistance of the separator, which in turn can improve the cycle performance of the battery cell using the separator; the addition of closed-cell materials can The diaphragm has a thermal shutdown function, which can improve the safety performance of the diaphragm cell; other preparation raw materials are wrapped and bonded by a binder, so that the diaphragm has integrity, and the subsequent application of the diaphragm can be used to bond the pole piece, Thus, the battery separator prepared by using the above-prepared raw materials has excellent mechanical properties, heat resistance and ionic conductivity. |
