I. Can a single label be used to identify that both lithium metal and lithium ion batteries are contained inside the package?
I--在IATA DGR 规定中，当包装件内同时装有锂金属和锂离子电池时，是否可以用一个标签来标明？
Yes. A single label identifying both lithium ion and lithium metal batteries may be used.
可以。可以用一个标签来同时标明包装件内即含锂离子电池，又含锂金属电池。
