As I look at electronics with weakening batteries, I wonder when they would be better with bulkier lithium iron phosphate batteries — 40% less energy density, but 10x the lifetime. Not much demand for ten year lifespan consumer electronics.

Similarly high cycle life with nickel cathode is possible if optimizing for that.
Adding silicon to (primarily carbon) anode, which improves energy density, reduces cycle life, due to large volumetric changes during charge/discharge.
