Up in anticipation of their product announcement Thursday where they announce they'll try for more government money via energy storage. Might as well give it a try, its not like they'll need all that many batteries for EVs. Problem might be that the storage arena is already crowded, GE, LG, BYD, etc.
Looking at Tesla competitors in energy storage, and some are using Li-ion like Tesla, but others are using other chemistries. I see that cycle durability is not Li-ions strong point. What chemistries are likely to be better suited and predominate in energy storage in 10 years?
