Degradation of li-ion batteries into finite recharge life-cycles, and with slow charging times, might just be due to how we are re-charging them now by plugging a "dumb" adapter into a wall socket. There are companies using AI to evolve the battery conditioning side of the recharge equation. Maybe old batteries will soon be resuscitated and reconditioned to extend useful lifespan? 45 patent applications by
this de-stealthed BEV grant recipient seems to suggest that capability may be just over the horizon.
