If the old cells were made easier to take apart and reassemble it would be helpful.
I think that someday the battery makers may do what Eagle Picher did for batteries on spacecraft. There is a container of electrolyte inside the battery. To activate the battery a small charge blows the electrolyte out of the container and into the cell, thus beginning the production of power. But instead of activation, the cell would be reactivated to nearly double its lifetime. It might be possible to add a third or fourth reactivation.
