> Industrial grid storage is rated to daily discharge for more than 10 years, with warranties typically around 12-14 years and expected life far afterward. 5000-10,000 cycles is more realistic. I'd be very, very interested in these lithium ion batteries that have a life span of 10,000 cycles. The only way this would be achieved is with a very small depth of discharge, which severely reduces usable storage. I at least provided a link to back up my claims, yet you accuse me of spreading misinformation despite not doing anything at all to back up yours. Alternative chemistries like lithium iron phosphate achieve 3,000 - 5,000 cycles [1] at 80% depth of discharge. They last 5-10 years, not 14 [2]. But that's a new batter chemistry with smaller share of the battery market than typical lithium ion, and they also have smaller capacities than lithium ion and lower max power output. Batteries are already being bottlenecked by input materials. Manufacturing accounts for only a quarter of a battery's cost [3]. Scaling out batteries is already becoming a problem of resource extraction. Even if the manufacturing cost is optimized to zero, the cost of inputs are still there. The cost of a new car went from a quarter of a million dollars in 1900 to $25,000 in 1920. Would it be reasonable to observe that the cost of a car was falling by a quarter every two decades and predict that a new car would cost $6,250 in 1940, $1,500 in 1960, and $100 by 2000? Why would this scaling stop? What's the limit? Why didn't cars keep dropping in price? 1. https://ecotreelithium.co.uk/news/how-long-does-lifepo4-battery-last/#:~:text=Lifepo4%20batteries%20have%20around%203000,fully%20discharged%20and%20charged%20again https://ecotreelithium.co.uk/news/how-long-does-lifepo4-batt.... 2. https://ecotreelithium.co.uk/news/how-long-does-lifepo4-battery-last/#:~:text=Lifepo4%20batteries%20can%20last%205,pack%20up%20sooner%20than%20expected https://ecotreelithium.co.uk/news/how-long-does-lifepo4-batt.... 3. https://www.visualcapitalist.com/breaking-down-the-cost-of-an-ev-battery-cell/ https://www.visualcapitalist.com/breaking-down-the-cost-of-a...
