How, by couping a country with a lot of lithium like Bolivia?
For starters... by getting rid of lithium. Alternatives might have a lower energy density in theory but also not the thermal issues of lithium-ion batteries. Which means you can pack them more densely without issues, or -even better- produce bigger cells instead of stacking small ones. So in practice they will perform on a similiar level but cheaper, making lithium-based batteries a niche product for high-end luxury items where you pay much more for a little bit of extra performance.
Next Step: You have batteries that don't run hot or might explode when damaged anymore? Stop putting them insinde the car but make the battery an integral part of the frame.
And that's just the theoretical side. The economic reality is that a lot of the benefits of lithium batteries are not based on the tech itself but coming from a decade of experience (and optimizations) in manufacturing. A lot of that experience is partly applicable to alternatives so they will reach a similiar maturity in a fraction of the time (= just a few years).
