A study of Li-metal batteries by the research team led by Dr. Byung Gon Kim at Next-Generation Battery Research Center of Korea Electrotechnology Research Institute (KERI) was published as a cover paper in the international journal ACS Nano.

While the current Li-ion batteries generate energy by taking Li-ions in and out of the graphite anode based on the intercalation mechanism, the Li-metal battery does not rely on this bulky and heavy graphite but uses metallic Li itself as the anode. As the Li-metal shows 10 times higher theoretical capacity (3,860 mAh/g) than graphite (372 mAh/g), it has steadily gained much attention from areas that need high-capacity batteries, such as electric vehicles and energy storage systems.

Despite this advantage, Li can grow in the shape of a tree branch, called a Li dendrite, if it is not uniformly and effectively stored when cycling process, leading to large volume expansion of the electrode, which in turn may shorten the battery’s cycle life and cause safety issue such as fire and explosion triggered by internal short-circuits.

Researchers at the University of Toronto and the Barcelona Institute of Science and Technology have recently created new solution-processed perovskite photodetectors that exhibit remarkable efficiencies and response times. These photodetectors, introduced in a paper published in Nature Electronics, have a unique design that prevents the formation of defects between its different layers.

“There is growing interest in 3D range imaging for autonomous driving and consumer electronics,” Edward H. Sargent told TechXplore. “We have worked as a team for years on finding new materials that enable light sensing technologies such as next-generation image sensors and striving to take these in a direction that could have a commercial and societal impact.”

Photodetectors, sensing devices that detect or respond to light, can have numerous highly valuable applications. For instance, they can be integrated in robotic systems, autonomous vehicles, consumer electronics, environmental sensing technology, fiber optic communication systems and security systems.

The media is going nuts over Elon Musk calling for more oil and gas at an energy conference in Norway, but the full quote is not being widely reported and brings some important context.

Earlier this year, Elon Musk called to drill for more oil, which raised a few eyebrows, but it was in the context of the Russian invasion of Ukraine and how it sent gas prices skyrocketing:

Gas turbines are widely used for power generation and aircraft propulsion. According to the laws of thermodynamics, the higher the temperature of an engine, the higher the efficiency. Because of these laws, there is an emerging interest in increasing turbines’ operating temperature.

A team of researchers from the Department of Materials Science and Engineering at Texas A&M University, in conjunction with researchers from Ames National Laboratory, have developed an artificial intelligence framework capable of predicting high entropy alloys (HEAs) that can withstand extremely high temperature, oxidizing environments. This method could significantly reduce the time and costs of finding alloys by decreasing the number of experimental analyses required.

This research was recently published in Material Horizons.

Tesla shared some new photos of the Tesla Semi on its website recently. Deliveries of Tesla’s all-electric Class 8 truck are expected to start sometime this year. It is also expected to be made with Tesla’s 4,680 cells. Earlier this month, Elon Musk said that Tesla’s 500-mile range Semi Truck will start shipping this year. He added that the Cybertruck would start shipping next year.

Today on Twitter, members of the Tesla community found new photos of the Semi that Tesla quietly uploaded to its website. @Tesla_Adri pointed out that Tesla added some new Tesla Semi press photos and that almost every image is new.

As the world increasingly embraces Web3, corporations are turning to metaverse applications to stay ahead of the curve. Based on Verified Market Research, the Metaverse market is anticipated to expand at a CAGR of 39.1 percent from 2022 to 2030, reaching USD 824.53 Billion in 2020 and USD 27.21 Billion in 2020. This is due to the increasing demand for AR/VR content and gaming and the need for more realistic and interactive training simulations.

These startups show Proof of Concept with a working product and clear value proposition for businesses and consumers.

● Launch a corporate accelerator: Another way to increase your exposure to the Metaverse is to launch a corporate accelerator. This will give you access to a broader range of startups and help you build a more diverse portfolio. In addition, it will allow you to offer mentorship and resources to the startups you invest in.

EU today — news, views, & analysis from across the EU & beyond.

Engineers at MIT have developed a new battery design using common materials – aluminum, sulfur and salt. Not only is the battery low-cost, but it’s resistant to fire and failures, and can be charged very fast, which could make it useful for powering a home or charging electric vehicles.

Lithium-ion batteries have dominated the field for the last few decades, thanks to their reliability and high energy density. However, lithium is becoming scarcer and more expensive, and the cells can be hazardous, exploding or bursting into flames if damaged or improperly used. Cheaper, safer alternatives are needed, especially as the world transitions towards renewable energy and electric vehicles.

So the MIT team set out to design a new type of battery out of readily available, inexpensive materials. After a search and some trial and error, they settled on aluminum for one electrode and sulfur for the other, topped off with an electrolyte of molten chloro-aluminate salt. Not only are all of these ingredients cheap and common, but they’re not flammable, so there’s no risk of fire or explosion.
