For consumers, the comparisons that work for EV are: (a) the distance you can cover between recharges, and (b) time-to-recharge. To create a market for EV, these need to compare favourably to internal combustion. It’s a tough sell, because in terms of energy density, battery technologies are not yet as good as liquid fuels, and that ultimately limits the range, efficiency, and convenience of EV.
Until the next breakthrough, LiFePO4 batteries have the fastest recharge time, and good power.
But what charges them? it all boils down to cost per watt.
At $1 per watt production cost, silicon solar cells are pretty good. But fusion will be better.
