Battery claims Battery claims December 26th 2024, grid scale batteries going cheap Normally I focus on technical advances, but these numbers are compelling. $66 per kw/h for storage combined with the cost of renewable energy makes for cheap reliable electricity. https://cleantechnica.com/2024/12/24/what-are-the-implications-of-66-kwh-battery-packs-in-china/ December 19th 2024, Sionic energy uses Group 14’s silicon anodes for high energy density batteries. 330wh/kg is achieved, compatible with existing manufacturing methods. They also claim 10 minute fast charging and a 1,200 life cycle. So in even a 200 mile range car that equates to 240,000 miles. 1,200 cycles isn't impressive by today's standards but given the realistic lifetime of a car it doesn't really matter. Who really expects an ICE car to last 240,000 miles let alone the 360,000 miles it would be in a 300 mile range car. Once again it's the type of energy density increase that would eliminate the weight diffe...
