I agree lithium future is bright. It is the best option for batteries right now.

Hydrogen is a source of energy that can be stored in low cost/ low tech gas bottles albeit low energy density if you want to combust it.
If you could bond it to atmospheric carbon atoms in certain combinations you can make high energy density liquids at room temp and use it in existing ICE engines and service station infrastructure... If the energy used to do that is renewable solar for example it could be an interesting carbon neutral option/competitor. There is also hydrogen fuel cells https://www.bmwblog.com/2019/07/01/hydrogen-powered-bmw-x5-reportedly-coming-soon/ to make electricity without carbon emissions in a form of hybrid.

You do actually use energy to mine, refine and make Lithium into batteries, and there is the issue of battery capacity decline over time and battery replacement / recycling energy requirements. The natural gas supply line was an important part of the salta brine processing for AGY process plant. Mining spodumene uses energy too particularly in the hydroxide processing plants powered mainly by coal power stations in China to make battery grade. The toxic tailings dust is an enviromental issue for the next few thousand years that we will have to find good options for long term storage - heavy metals and radioactive elements left over after lithium processing is complete are a threat to ground water and process workers (in the form of respirable dust) and the community near tailings storage facilities.

No silver bullets when it comes to energy.
