BYD confirms new 1000V Super E-Platform capable of fast charging 400 km in 5 min (electrek.co)
We EV enthusiasts have heard it all from the haters before. “What are you gonna do with all those batteries?” “There’s just not enough range,” and, of course, “Charging takes so much longer than a gas station visit.” As previously teased, Chinese auto conglomerate BYD has introduced a new 1,000-volt EV platform that can enable charging rates as fast (or perhaps faster) than a trip to the gas station. We’re talking five minutes.

Rechargeable paper battery is cheaper, safer and as powerful as lithium (newatlas.com)
A battery that's safer and cheaper than lithium-ion while offering comparable energy density? That sounds like a pipe dream. But such a battery is in fact in the works, using a chemistry of renewables to store over 220 Wh/kg. Singaporean startup Flint believes it has the formula for the most sustainable battery the world has ever seen, capable of replacing lithium for applications like EV power and grid storage. Maybe that is a dream.

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.
