> That said, grid batteries should ideally be using different chemistry to handle the increased charge/discharge cycling. I completely agree with this. It would actually be quite unusual if the same solution fit such different problem domains. Energy density by weight is an (almost) non issue in fixed installations, by volume only slightly more important. Lifetime cost and maintenance requirements as by far the largest issue. At the moment it feels like the stage in the 60s where people thought turbines were interesting so tried to cram them into cars, trucks and trains. Except here we are trying to wire together millions of tiny lithium cells to get enough energy to power a country.

Energy density by weight is an (almost) non issue in fixed installations, by volume only slightly more important. Lifetime cost and maintenance requirements as by far the largest issue. Likewise. It currently seems to me that the same chemistries are being used for both simply because the cost reduction due to mass production for cars has made it the current cheapest option, but I don’t expect that to be true forever.
