RWE is using used lithium batteries from electric vehicles in the new storage unit. The 60 battery systems in the innovative storage unit on the site of the RWE pumped storage power plant in Herdecke, North Rhine-Westphalia, can buffer around 4.5 megawatt hours of electricity.
At the touch of a button, the car changes colors.
The surface coating of the BMW iX Flow featuring E Ink contains many millions of microcapsules, with a diameter equivalent to the thickness of a human hair. Each of these microcapsules contains negatively charged white pigments and positively charged black pigments. Depending on the chosen setting, stimulation by means of an electrical field causes either the white or the black pigments to collect at the surface of the microcapsule, giving the car body the desired shade.
Just don’t expect to see this at your local BMW dealership anytime soon: the automaker says this is just an “advanced research and design project.”
The innovative paint scheme can be triggered at the touch of a button. Right now, the colors are limited to white, black, and grey. But despite the constrained palette, BMW says it could have implications for the efficiency of its electric vehicles.
Even though solid state batteries are seen as technology that could drastically improve today’s fully-electric vehicles, it seems the first vehicles to feature one won’t actually be EVs. This is at least true in Toyota’s case since the manufacturer has now confirmed that its first solid state-equipped vehicles will be hybrids expected to debut in two or three years’ time.
The news comes from Gill Pratt, Toyota’s chief scientist and head of the Toyota Research Institute, who made the announcement during an interview for Autoline. He also mentioned that the manufacturer has made progress with its solid state project and that development is on schedule.
He did not say which hybrid Toyota will get a solid state battery, but he did go on to explain why it won’t immediately offer solid state EVs. The main reason has to do with the size of the battery pack, which for a hybrid vehicle that still has an internal combustion engine, is considerably smaller than what you see in pure EVs.
On January 6, 2022, a Tesla Model S P85 (the oldest performance version) reached an impressive mileage milestone of 1,500,000 km (932,256 miles).
The car is used in Germany by Hansjörg von Gemmingen — Hornberg, who is known in the EV world for setting the highest mileage records in Tesla cars.
A wind turbine sitting idle on a calm day or spinning swiftly when power demand is already met poses a problem for renewables, and is one researchers think can be tackled under the sea.
In one vision, offshore wind farms could use seawater to essentially store energy until it’s needed, helping wean humanity off fossil fuels.
“We came up with a solution that we call the ocean battery,” Frits Bliek, CEO of Dutch startup Ocean Grazer told AFP while showing off the system at the CES tech fair in Las Vegas.
All-solid-state batteries are now one step closer to becoming the powerhouse of next-generation electronics, as researchers from Tokyo Tech, National Institute of Advanced Industrial Science and Technology (AIST), and Yamagata University introduce a strategy to restore their low electrical resistance. They also explore the underlying reduction mechanism, paving the way for a more fundamental understanding of the workings of all-solid-state lithium batteries.
All-solid-state lithium batteries have become the new craze in materials science and engineering as conventional lithium-ion batteries can no longer meet the standards for advanced technologies, such as electric vehicles, which demand high energy densities, fast charging, and long cycle lives. All-solid-state batteries, which use a solid electrolyte instead of a liquid electrolyte found in traditional batteries, not only meet these standards but are comparatively safer and more convenient as they have the possibility to charge in a short time.
However, the solid electrolyte comes with its own challenge. It turns out that the interface between the positive electrode and solid electrolyte shows a large electrical resistance whose origin is not well understood. Furthermore, the resistance increases when the electrode surface is exposed to air, degrading the battery capacity and performance. While several attempts have been made to lower the resistance, none have managed to bring it down to 10 Ω cm2 (ohm centimeter-squared), the reported interface resistance value when not exposed to air.
Lithium metal batteries could store much more charge in a given space than today’s lithium-ion batteries, and the race is on to develop them for next-gen electric vehicles, electronics and other uses.
But one of the hurdles that stand in the way is a silent battle between two of the battery’s parts. The liquid between the battery electrodes, known as the electrolyte, corrodes the surface of the lithium metal anode, coating it in a thin layer of gunk called the solid-electrolyte interphase, or SEI.
Although formation of SEI is believed to be inevitable, researchers hope to stabilize and control the growth of this layer in a way that maximizes the battery’s performance. But until now they have never had a clear picture of what the SEI looks like when it’s saturated with electrolyte, as it would be in a working battery.
Aluminium Air batteries have been a thing for a while — but now a UK inventor says he’s solved one of the biggest problems with them — the toxicity of the electrolyte they’ve traditionally used.
Does this make Aluminium Air batteries viable?

Net-zero architecture is what will reduce emissions from the construction industry on a large scale. But make it inclusive as well as scalable and you also get a solution that can lift homeowners out of poverty while building a community! Created for that very purpose, these solar homes are aiming to help solve both the global housing and climate crises with one design. The houses produce their energy, harvest 100% of the rainwater, clean their sewage, and also have the potential to grow their own food!
It is called the PowerHYDE housing model and was created by Prasoon Kumar and Robert Verrijt of Billion Bricks from India and Singapore. The model explores sustainable solutions to empower and facilitate growth opportunities for people without homes around Southeast Asia which has a lot of rural and low-income populations. These homes not only provide shelter but are also a power module to scale sustainable communities that lift homeowners out of poverty!
