We had several incidents with cargo 'planes over the last two years.
Solutions.
The consignments which contain the batteries should not be carried as general freight added onto pax flights.
You have specially equiped freighters that can carry these goods.
No longer are they to be shipped in general cargo freighters.
In all cargo freighters you can seal the flight deck from fumes in a much better way than already done.
You make all freight decks ambient temp of no more than say 20C.
These are the techincal challenges. The rest is people management.
