Newly created diamond 'batteries' use carbon-14 to produce microwatt-levels of power for decades. Potential applications include implanted medical devices and instruments in spacecraft.

'A closer inspection of ash from burned rice hulls, the hard outer layer of rice grains, revealed a form of carbon that could nearly double the energy density of typical lithium-ion or sodium-ion batteries.

This sustainable source of ‘hard’ carbon, which outperforms ordinary graphite in battery electrodes, was discovered at the University of Michigan.'

South Korean companies are reconsidering their $54 billion investment blitz to build electric-vehicle battery plants in the U.S. over concerns President-elect Donald Trump could undo tax credits for EVs. https://www.japantimes.co.jp/business/2024/12/09/tech/trump-ev-korean-investments/?utm_medium=Social&utm_source=mastodon #business #tech #electricvehicles #southkorea #lg #samsung #batteries #donaldtrump

"The recent price cuts come from a deliberate decision to use abundant earth materials such as iron and phosphorus wherever possible.

These #batteries are cheaper, as they have no #cobalt. They have other benefits too: a longer usable life and less risk of fire than traditional #lithium battery chemistries. The downside is they have lower capacity and voltage."

Not all #batteries work on chemistry.

"When wind or solar power is abundant, the energy can be used to compress carbon dioxide gas into a liquid. When extra energy is needed, the liquid will be allowed to decompress, turning back into gas and powering a turbine to generate enough electricity to power up to 20,000 homes. "

“Right now we have nothing that can buffer a 4 megawatt solar field.”

"Ambitious young EV automaker #ZEEKR is claiming a “new charging speed record” using its latest model and new lithium-iron-phosphate (LFP) #batteries, unveiled during a Tech Day event in China today. ZEEKR states that its new batteries can recharge its EVs from 10-80% state-of-charge as quickly as 10.5 minutes. "

So apparently lithium batteries in kerbside bin are being blamed for a spate of fires in waste collection trucks;

Yet another reason obliging anyone who sells electronic devices to accept end-of-life ones for recycling, at their own expense. The disposal of this waste needs to be made a cost of doing business that produces it. Not externalised onto citizens as consumers or via public waste management budgets.

If you live in a place with flexible electricity pricing based on demand than it can make sense to install batteries even if you don't have solar because so many of our grids are starting to have a duck curve from photovoltaics.

You can recharge your batteries while the energy is cheap or even free and then use that stored electricity in the evening instead of buying it from the grid when their prices have gone up because they fired up their methane burning plants.

One major climate message that we've really got to elevate above all others is that addressing global warming is way, way, way, way less expensive than ignoring it!

The cost of solar power has dropped around 90% over the past decade, and battery storage costs dropped 85% during the same period.

Remember: fossil fuel companies want people to focus on what **uses** #energy so we don't talk about the supply side.

They benefit from #environmentalists spending time and energy bickering with one another about whether AI uses too much #electricity, whether to support more #nuclear plants, whether we should mine more #lithium to have grid scale #batteries, and so forth.

That doesn't mean we can't talk about these things, but be #mindful where you spend your energy.

Lithium industry braces for long-term oversupply after price instability

> A stuttering recovery in lithium prices is providing a fresh reminder of why the dramatic rally of recent years was followed by an even more breathtaking collapse: a fast-expanding industry that is more prepared than ever to keep pumping out supplies.

According to a report by BloombergNEF, it is estimated that by 2030, there will be around 1.2 million tons of retired EV batteries worldwide.

Researchers at Oak Ridge National Laboratory have developed a new technology enabling EV battery reuse: a type of power electronics equipment that can manage a variety of EV batteries as an energy storage system for an electric utility.
