一种锂离子电池铝合金防爆片
摘要：
本发明提供了一种锂离子电池铝合金防爆片，其中，以锂离子电池铝合金防爆片的总质量为基准，包括：Mg为1.01~1.05wt%，Mn为0.43~0.45wt%，稀土元素为0.1~0.5wt%，剩余部分由铝和杂质构成，并且，作为杂质的Si为0.015~0.02wt%。同时，本发明还提供了一种上述铝合金防爆片的制备方法。本发明提供的锂离子电池铝合金防爆片，起爆压力稳定，能保证锂离子电池的安全性能。
摘要（英）：

The invention provides an aluminum alloy anti-explosion sheet for a lithium ion battery. By reference to the total mass, the aluminum alloy anti-explosion sheet for the lithium ion battery comprises the following components in percentage by mass: 1.01-1.05% of Mg, 0.43-0.45% of Mn, 0.1-0.5% of rare earth elements, and the balance of aluminum and impurities, wherein the impurities are 0.015-0.02wt% of Si. In addition, the invention further provides a preparation method of the aluminum alloy anti-explosion sheet for the lithium ion battery. The aluminum alloy anti-explosion sheet for the lithium ion battery is stable in explosion pressure, and capable of ensuring the safety property of the lithium ion battery.
