Eco-friendly aluminum battery lasts 10k cycles with minimal loss (techxplore.com)
Large batteries for long-term storage of solar and wind power are key to integrating abundant and renewable energy sources into the U.S. power grid. However, there is a lack of safe and reliable battery technologies to support the push toward sustainable, clean energy. Now, researchers reporting in ACS Central Science have designed a cost-effective and environment-friendly aluminum-ion (Al-ion) battery that could fit the bill.

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.
