Existing Lithium Carbonate batteries are lasting longer than expected. You can pretty much expect 1 million miles off existing battery tech. Solid state may/may not charge much faster (heat issue), but they look pretty decent for life extension due to dendrite growth being unable to penetrate the "glass" membrane.

Graphene is still laboratory, and doesn't have the energy density needed. Until we update the Periodic Table, Lithium looks like a strong contender for the next decade. Bear in mind, EV have huge benefits in reduction of moving parts, your EV may have less than 20 moving parts (including transmission) whereas your Internal Combustion Engine will have over 1,000 - any one of which failure will render your car inactive. The EV with all wheel drive, has redundant in the event of a failure. Further, no oil changes, brake life extended exponentially, figure 200-500k miles between maintenance cycles.

And companies like American Battery Metals (ABML) can recycle the entire used EV battery, at 95+% recovery, reclaiming everything.

Lastly, there is only 1 source of fuel for internal engines - fossil fuel. Your EV can be charged by any means that generates electricty.
