battery claims
Battery claims Battery claims May 31st 2025, An Indian Sodium Ion battery No mention of energy density but a 3000 cycle life. Cycle life seems a theme this week. We have a Lithium Metal high energy density battery with under 500 cycles and CATL with a decent energy density sodium battery boasting 10,000 cycles. In a car the difference is meaningless 3000 cycles is the better part of a million miles. In a grid battery it's the difference between an 8 year lifespan and a 25 year lifespan. On the face of it, the Indian Battery has a hard road to production. https://energy.economictimes.indiatimes.com/news/power/indias-superfast-sodium-ion-battery-charges-80-in-six-minutes-could-cut-lithium-imports/121352254 May 30th 2025, CATL makes Lithium Metal breakthrough The battery has 500wh/kg energy density but a life cycle given as 483 cycles which in a car with 300 miles of range would only give a sub 150,000 mile lifetime. Perhaps it will end up in aviation? https://insid...
