I have no idea what you're trying to say or if you're being sarcastic. There are multiple battery chemistries including lithium iron phosphate (7x cycle lifetime), lithium titanate (50x cycle life or more) and sodium ion (potentially cheaper) that are all on the market to buy right now, not to mention lithium polymer batteries and all the refinements and variations out there.
