Lithium Bubble ??, page-135

ABCASH, yes I am assuming lithium will be in great use in 20 years time and not just for batteries either.
The people putting billions of dollars into the gigafactories around the world also think that lithium batteries will be a major component of society for many years, so it is very difficult to go against their logic.
Most of the possible replacement batteries that scientists are working on also have lithium as part of their chemistry. As it is the lightest metal, it will be difficult for something better to come along for transport, as most other materials are heavier, and I haven't seen any suggestion of a hydrogen or helium battery. Plus at I stated somewhere else fuel cells just are not going to be able to compete against lithium batteries. The life time of the fuel stacks are not good, worse than Li-on batteries plus there is the cost of hydrogen at the station, compared being able to charge your car at home for free off the solar panels on your roof.

The lithium batteries in 20 years time might be slightly different to today, but I'm very confident they will still be a major part of society in 2036.
