Thanks for advice. As you will know there have been some fatal incidents on freighters due to fire. As yet we had no formal report on what caused the fires or suspected fires.
Now it would be fair to guess that the cells themsleves could be made in say A then shipped in bulk to B for a consumer product. It is these large consignments that focus my mind.
How could you pack these cells so they are less prone to self ignition? Thats whay I ask about the vacuum. Am I correct in thinking the cells need air to combust...or are the oxides already in the cell content?
