on 02025-06-17#video from a month ago saying lithium iron phosphate #lithium-ion #batteries had fallen in #pricing in December to US$115/kWh (US$32/MJ), quoting BloombergNEF. Says raw materials are 70% of batteries’ cost [citation needed], and that LFPs have #energy-density of 90–160Wh/kg (320–580kJ/kg), much worse than NCA (230–260Wh/kg) or NMC (250–320Wh/kg), citing a page on batterydesign.net. #energy
