A regular double A doesn’t contain lithium. Lithium is a very reactive metal. When exposed to air it reacts and creates a lot of heat, causing other stuff to heat up. In a typical Li Ion cell, there’s an electrolyte, which can boil off and cause an explosion. Also, in contact with water, which is also in the air, hydrogen can be formed, which in the right mixture with oxygen, can also be explosive.
