A camera battery with a USB-C port is a gadget whose time has come – Glad 3rd parties are helping bust proprietary vendor lock-ins

Bild/Foto
The Nitecore UFZ100 camera battery is here to release photographers from Sony’s proprietary grasp — a built-in USB-C charging port lets you power it up using the same hardware as many of your other devices. It hasn’t been officially released yet, but you can use the battery with the Sony A7 III, A7R III, A7R IV, A7S III, A9 (ILCE-9), A9 II, A6600, A7C, A1, FX3, and A7 IV, saving you from lugging around a separate charger if you want to bring along (and charge) an extra battery on a shoot.

Reliability and price have not been made known yet though. So yes there may be some trade-offs as certainly the capacity is slightly less, with a longer charging time.

Theion’s Sulphur Battery Technology Could Make Electric Cars Go Three Times Further By 2024 with no Rare Earth minerals

Bild/Foto
Sulphur is the tenth most abundant element on Earth, and local sources are usually available in any chosen location in the world. There is no nickel, no manganese, no cobalt, and they replace the current collective folds of copper and aluminium with graphene, so they have also no aluminium and no copper in their cells either. The only things they have in their cells are lithium metal foil, sulphur, and carbon. To make this technology work, the sulphur must be melted to form crystals, but this is only 112C (235F).

Ehmes claims Theion’s technology will radically increase both gravimetric and volumetric density, so that its batteries either take up less weight and space for the same capacity, or you can have much more capacity for the same weight. Theion’s Gen 4 battery, due in 2025, will have a slightly lower gravimetric density of 900Wh/kg, but a higher volumetric one of 1,500Wh/liter – so it would take just over a quarter of the space of a Tesla Model 3 Long Range battery. Theion is also promising 2,000 charge-discharge cycles for its Gen 3 and 4 technologies, which is above the 1,000-1,500 cycles of current Lithium-Ion cells.

Unfortunately, Theion isn’t initially going to be delivering its technologies to the EV industry. “We’re currently talking to the space industry,” says Ehmes. “We will hand over the R&D surplus to the air taxi next. Then mobile devices like handhelds, laptops, mobile phones, and wearables.” But EVs are definitely on the roadmap for Theion, and production has been designed to scale up to the quantities required by electric cars.

Replaceable Batteries Are Coming Back To Phones If The EU Gets Its Way… Apple Will Tell Us This Is Bad For Us

Bild/Foto
Back in the day, just about everything that used a battery had a hatch or a hutch that you could open to pull it out and replace it if need be. Whether it was a radio, a cordless phone, or a cellphone, it was a cinch to swap out a battery.

These days, many devices hide their batteries, deep beneath tamper-proof stickers and warnings that state there are “no user serviceable components inside.” The EU wants to change all that, though, and has voted to mandate that everything from cellphones to e-bikes must have easily replaceable batteries, with the legislation coming into effect as soon as 2024.

Many phone batteries are designed to be non-replacaeble from the factory. Thus, when they swell up or fail, they can damage the whole phone rather than merely popping off a removable panel.

I remember the early Samsung phones had a rubber gasket on the battery cover to also help keep water out. Point is most people’s phones don’t get taken swimming, but the first thing normally to fail on a very very expensive phone, is the battery. I anyway have always taken out all-risk insurance on every phone and tablet I’ve bought (which excludes failed batteries). Personally, I’d be happy to see replaceable batteries again, as I have still not forgotten my Nexus 6P battery failure which turned my phone into an expensive brick. And of course this is not just about phones, and also includes rechargeable toothbrushes and other devices, which is better for the environment.

Use This Free App to Make Your MacBook’s Battery Last Longer – AlDente can help slow the process

Bild/Foto
Modern MacBooks feature exceptional battery life, but like most batteries, they will degrade over time. Around a year after you buy a MacBook, its battery begins to show some performance issues, and their ability to hold a charge diminishes the longer you use them. There’s not much you can do to stop this process from happening, but there is an app that can help reduce the speed at which your MacBook’s battery degrades.

AlDente’s free tier lets you set both a lower and upper limit on how much your MacBook can charge. If you set these limits between 20 and 80%, you’ll be able to maintain your MacBook’s battery health for much longer. You can also force your MacBook to run on battery power, even when it’s connected to a charger. Whenever your MacBook hits the 80 percent charged mark, AlDente will make it switch to battery power until it reaches the lower end of the charging limit.

With Apple’s Optimised Battery Charging, MacOS will try to find out your charging and working schedule and prohibits charging above 80% for a couple of hours overnight. If you have an unregular schedule, this will not work, and it will still charge up to 100%, just a little bit later. With AlDente, you take full control over your MacBooks charging behaviour.

Solid State Batteries for EVs are still not here, but Tesla's new tabless 4680 battery offers 5x the energy, 6x more power, and 16% increase in range from 2022

Not exactly revolutionary, but a large incremental gain across many fronts with Cobalt being dropped, the Graphite anode is being replaced with Silicon, the tabs are being dropped which reduce costs and formation of hotspots, and the larger size overall benefits capacity and costs.

The new design is 56% cheaper to produce and needs about half the real estate to generate the same power as a 74 kWh Model Y battery pack.

The redesign also means it could well exceed a 1 million mile lifetime use, with 94% of its life being retained after 4,000 charge cycles. It will also allow for a far faster charging time of around 15 minutes.

Solid state batteries should be the Holy Grail of batteries (long range with less fire risk), and they are in limited use, but the cost factor right now is too exorbitant for EVs and a breakthrough in that aspect is still needed.

It's all a Scam! - Before Replacing Your Phone Battery, Watch This - Scams Explained

`The $3 replacement "higher capacity" battery I bought off AliExpress for a Fitbit Alta HR has had a terrible battery life of around two days. I checked the iFixit site, and the battery sells there for $20. Now, after watching this video, I really suspect I was sold a useless dud. Possibly the same thing happened with my Nexus 6P battery.

So useful to watch, and do a little more research before just buying that cheap "genuine" or "higher capacity" replacement battery. You get what you pay (or don't pay) for.

Scientists at the ReCell Center have taken another step towards making EV battery recycling more economical

Scientists in the Materials Engineering Research Facility at Argonne are scaling up MTU’s innovative separation process, paving the way for the large-scale recycling of EV batteries.

In a new paper published in the peer-reviewed scientific journal Energy Technology, MTU and ReCell researchers detail their discovery: a method of separating individual cathode materials using a new twist on an old process called froth flotation. Used for many years by the mining industry to separate and purify ores, froth flotation separates materials in a flotation tank based on whether they repel water and float, or absorb water and sink.

Once the cathode materials were separated, the researchers determined through testing that the process had a negligible impact on the electrochemical performance of the materials. Both also had high purity levels (95 percent or above).

Whoop’s new fitness tracker is better thanks to a battery breakthrough - Sila Nanotechnologies’ silicon anode has finally arrived

Fitness company Whoop has a new tracker that squishes five LEDs, four photodiodes, a pulse oximeter, skin temperature sensor, and more into a package that is 33 percent smaller than its predecessor — all while still offering five days of battery life. But a particular change to the tracker’s battery chemistry is one of the biggest reasons Whoop was able to do all this in the first place.

The change was pioneered by a Silicon Valley company called Sila Nanotechnologies, which was co-founded in 2011 by Gene Berdichevsky, one of Tesla’s earliest employees. And it’s one that, if it scales up, could help break some of the biggest limitations currently facing lithium-ion technology.

On paper, it’s a simple change: the battery’s anode is now made of silicon instead of graphite, which allows for greater energy density (up to 20 percent, Sila claims). Greater energy density means device makers can use a smaller battery to accomplish the same tasks — or free up more space to do things they couldn’t before. And it doesn’t require any hardware changes to the cell production process. In fact, that’s one of Sila’s biggest selling points to battery makers: its silicon anode is more or less plug-and-play.

Finding solutions to climate change is not as easy as you may think.

On the dark side:

On Contact: Mainstream Environmental Movement Lies.

https://www.rt.com/shows/on-contact/533294-mainstream-environmental-movement-lies/

The mainstream environmental movement receives a lot of criticism for their proposed ‘green’ technical solutions to climate change.

”This is a fantasy sold to us by an environmental movement that promises we can continue to indulge in orgies of consumption and maintain the levels of waste and perpetual growth that define the industrial age.”

On the bright side:

China maintains 'artificial sun' at 120 million Celsius for over 100 seconds, setting new world record.

https://www.globaltimes.cn/page/202105/1224755.shtml

Medium: The Earth has 57.27 million square miles of land, we only need to convert 0.2% of it to solar.

https://medium.com/predict/why-dont-we-cover-the-sharah-in-solar-panels-3692a5bf89bd

”We can power the whole world with a relatively small amount of solar panels. The Earth has 57.27 million square miles of land, we only need to convert 0.2% of it to solar, and we can power ourselves entirely. To give some perspective, it is estimated that 1% of land is built up and human-occupied (cities and towns not farmland). In other words, if we can convert 20% of urban areas around the globe to have solar on them, then we can fully power ourselves!”

However, large-scale photovoltaic solar farms envisioned over the Sahara desert would do more harm than good:

https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2020GL090789

”Large-scale photovoltaic solar farms envisioned over the Sahara desert can meet the world's energy demand while increasing regional rainfall and vegetation cover. However, adverse remote effects resulting from atmospheric teleconnections could offset such regional benefits. We use state-of-the-art Earth-system model simulations to evaluate the global impacts of Sahara solar farms. Our results indicate a redistribution of precipitation causing Amazon droughts and forest degradation, and global surface temperature rise and sea-ice loss, particularly over the Arctic due to increased polarward heat transport, and northward expansion of deciduous forests in the Northern Hemisphere.
