Aluminum batteries outlive lithium-ion with a pinch of salt (ieee.org)
Electric vehicles( EVs) and green energy sources rely heavily on batteries to store electricity. Currently, more than 75 percent of the world’s energy storage depends on batteries that contain lithium, an expensive mineral that’s subject to volatile pricing. Lithium-ion (Li-ion) batteries themselves can be volatile, too, because they use a flammable electrolyte that can catch fire when overcharged.

California went a record 98 days with 10 hours of electricity from renewables (grist.org)
A new study in the journal Renewable Energy that looked at California’s deployment of renewable power highlights just how reliable the future of energy might be. It found that last year, from late winter to early summer, renewables fulfilled 100 percent of the state’s electricity demand for up to 10 hours on 98 of 116 days, a record for California.

Lithium-Ion Battery Pack Prices See Largest Drop Since 2017, Falling to $115kWHr (bnef.com)
New York, December 10, 2024 – Battery prices saw their biggest annual drop since 2017. Lithium-ion battery pack prices dropped 20% from 2023 to a record low of $115 per kilowatt-hour, according to analysis by research provider BloombergNEF (BNEF). Factors driving the decline include cell manufacturing overcapacity, economies of scale, low metal and component prices, adoption of lower-cost lithium-iron-phosphate (LFP) batteries, and a slowdown in electric vehicle sales growth.

Solid-state batteries enter pilot production, costs expected to drastically drop (pv-magazine.com)
The push to commercialize solid-state batteries (SSBs) is underway with industries from automotive to storage betting on the technology. But while the hype around full solid-state batteries has somewhat subsided, with the technology taking longer than expected to take off, semi-solid-state batteries, which use a hybrid design of solid and liquid electrolyte, have been making steady progress toward commercialization.
