I do appreciate batteries will be recycled but I am not sure if all of the contents will be of any use in ten years time when the make up may have changed
. As things stand the car makers have different ideas on the type and sized and everything else on these cars. It does seem that by the time the current cars have reached the point the batteries need replacing, there will be a multitude of batteries with specific ones needed for different cars, and while the battery costs may have dropped this incompatibility point will have pushed other costs up. If you want to replace the batteries in a current car you ae stuck with whatever the maker wants to charge as other makes batteries will not generally fit. Whatever though you are going to have a major job and I do not see the costs coming down to the point where someone with a ten year old car will will always wish to spend that sum on a car now worth not a lot more than the batteries and fitting cost.
What we need is standardisation, so as with any ICE you can recharge anywhere with out specific adaptors and the supply and fitting need for new batteries will need sorting.
I have different perspective. Virtually every constituent of present day batteries when recycled correctly will produce materials, which will have use for many years to come. Just becasue a material has come from a battery does not mean it has to be used in a battery.
As I pointed out previously present day car batteries use multiple individual cells just wired (Vastly over simplified) together. And cells that are usable can be removed and fitted into another battery pack. It doesn't have to be the same make of car battery it just needs to use the type of cell.
For that reason there are already some companies that are repairing battery packs using components from crash damaged packs.
It's too early to find enough examples of what motorists will want to do when they reach the point of needing to replace a battery outside of the warranty period, but I suspect it will follow what presently happens when ICE cars reach the point that a new engine might be required. I'm certain that some will be keen to replace EV batteries but some will not think its worth it. What is significantly different is how ICE cars often show signs of damaged associated with engine vibrations, which EV simply don't suffer, so the condition of a similarly aged and used EV may be better than the ICE so it may a more attractive proposition to consider a replacement battery.
I agree with your points about paying for public charging. It definitely needs to be improved. There should be more charging locations and Its presently far to fragmented with too many separate apps. It should be like a fuel station where you arrive plug in and pay with a debit or credit card or even cash.
There already is a fair degree of standardisation regarding the connectors required. For good technical reasons, there has to a couple of types of charging connectors to segregate AC and DC systems.
