No, battery tech has pretty much hit the peak of its abilities as a matter of simple physics. Any mooted solutions to the energy density issue are variations on the same theme of two electrodes, a separator, and an electrolyte, with some small percentage increase of specific energy over current technologies, accompanied by a similar increase of all the risks inherent in the current, extremely high density configurations these cells use. It's that high density configuration itself that causes all of the problems. Lithium can spontaneously deposit on one of the electrodes and form whiskers that breach the separator, causing a short circuit. Heat can cause spontaneous short circuits as well, by compromising the insulating properties of the separator, as can cold, in different ways. Cells lose capacity over time, losing it faster while charging and discharging, and will eventually become unchargable as a result. Requiring the cost of a full engine out and rebuild to replace what is effectively the fuel tank is a ridiculous proposition.Battery tech changes fast and we are still in early stages here. There will be aftermarket solutions in future as market matures
I have no issue with electric cars as such (I'm planning to convert a car to electric at some point, though ideally I'd go for hydrogen fuel cell rather than battery). My issue is that people are blindly accepting impossible promises about electric vehicles, not least regarding the unphysical "future" of battery tech, while governments are legislatively designating BEV as the "winner", and either using taxation or outright bans to force people out of reliable, efficient, inexpensive (were the government not intervening in the price) vehicles that will outlast almost any BEV you can point at, without suffering any equivalent lifetime range reduction in the process.
e: also learn how to multiquote. Triple-posting makes you gay.
