There's still a lot of lithium around. Sodium batteries are available now and scaling up, they will take over for stationary storage.
Molten salt has the drawback that converting heat to work has 30-40% efficiency, max.
Gravity is simply out of the question. Storing 10 kWh requires lifting 100 tons 36 meter. We need that per person, just for daily solar storage. By comparison 10 kWh battery is less than $1000 and falling.
