For sure. They would likely use a lower capacity battery due to these being much less energy dense, though. Hybrids have been using bigger batteries and only using around a 30% zone of charge state in order to greatly prolong battery degradation. I’d imagine auto makers would try to keep the batteries around the same size, but start using more like a 60 or 70% zone, though. So they’ll take advantage of that higher cycle life.

You won’t get an automaker to care about making a battery that lasts much beyond 10 years.
