USGS uses machine learning to show large lithium potential in Arkansas

Me thinks we might switch batteries to sodium in just a few years.

I think there will be markets for many different chemistries and there's unlikely to be some total winner in the near future. Each chemistry has its own tradeoffs and use cases. Some will fade and die over time like Ni-Cad, but even that takes longer than you would expect.

It would be amazing for some low weight, low volume, high energy density, high discharge rate, high charge rate, cheaply manufactured from abundant materials, low thermal sensitivity, high thermal tolerance, low passive loss, non-explosive, high cycle count, low memory, shelf stable battery chemistry to appear, but thus far every one fails in several of the categories.

Where does LFP fail? Today's LFP batteries are getting pretty damn good.

Energy density, weight, cost, and discharge rate.
