Disposable primary lithium batteries must be distinguished from secondary lithium-ion , lithium iron phosphate and lithium-polymer ,  which are rechargeable batteries. Lithium is especially useful, because its ions can be arranged to move between the anode and the cathode , using an intercalated lithium compound as the cathode material but without using lithium metal as the anode material. Pure lithium will instantly react with water, or even moisture in the air; the lithium in lithium ion batteries is in a less reactive compound.
Lithium-ion batteries (UN No. 3480) are classified as Dangerous Goods under the Australian Code for the Transport of Dangerous Goods by Road and Rail ( ADG Code ).

Internal or external short circuit, environment excessive heating, deep discharging and overcharging are the most common cause the temperature rising over the thermal runaway border and makes a safety problem. In modern technology, most lithium ion/lithium polymer cells can pass all of the Lithium ion safety codes except short circuits. Of course for small, low power cell, some companies introduce PTC, Pressure Release Disks, etc. in their lithium ion cells internally to manage external short circuits. However, this solution can only be used in low current rate cells, or the user may accept lots of energy losses in the cell.
