Global car sales are about 75 million; at 80 kWh per car with pure electric that’s 6 TWh/year of battery demand. Leaves about 2 TWh/year for stationary storage. 15 year lifespan of batteries, so that would asymptote to 30 TWh of installed stationary storage, or about 9 hours backup for the entire global grid.
Stationary storage will probably go somewhat higher than this long term term as global electricity demand grows, but yeah… 8 TWh/year of supply will be enough for quite a few years.

This is great, but is it already the year 2025?
