Imagine the power you have now.

With great power comes great responsibility.

Lithium is also a group-1 alkali metal and reacts violently with oxygen just like sodium, in both air and water. Once it is burning, it is difficult to extinguish because water also contains oxygen (H2O) which means it will burn in water and firemen have to use enormous amounts of water to try and cool the metal to the point that it stops combustion. Usually, the firemen have to just let it burn itself up while protecting the surroundings from catching fire. Lithium batteries are everywhere and there are hundreds of stories of them spontaneously catching fire from overheating. I predict that in the next 10-20 years, the number of old phones and other items with Li batteries, sitting in drawers and junk piles in peoples' homes as items they no longer want, will start numerous fires as the items' batteries degrade, short across the layers, and then start combusting. A damaged or overheated lithium battery is essentially a thermite grenade waiting to go off. Old lithium-battery-containing items that are thrown in the trash are already responsible for numerous landfill and garbage fires. I predict that sometime in the future they will be banned as a consumer item and only used in special applications, e.g. large electrical storage farms or military devices, where they can be monitored continuously. In my home, I counted over 30 items containing small or large lithium batteries. Even now, it is recommenced that you "don't leave lithium batteries on chargers unattended", as stated on numerous devices I own. There's a good reason for that.

Addendum to my original post. See this article: Daily Mail Link. Be afraid. Be very afraid. Note that the article implies there's no place to dispose of these. Anywhere. You just have to dig a deep hole in the ground and bury them, I suppose.

The stem is also covered with the same spikes and the seeds are spread by the wind or birds or roos as we have had a number sprout in our yard over the last three years. I think probably by birds as they always sprouted under tree branches.

And the pain from picking up a leaf is not that bad at all.
