Lithium-ion batteries with recycled metals nearing production in the US

Posted by in categories: energy, nanotechnology, sustainability

We could soon see more lithium-ion batteries made with recycled materials thanks to a new partnership. BASF, a battery materials producer, has announced that it’s teaming up with Nanotech Energy, a maker of graphene-based energy products, to produce lithium-ion batteries with recycled materials for customers in North America.

While BASF will create the cathode active materials using recycled metals from a Battle Creek, Michigan facility, Nanotech will use those materials to create the lithium-ion battery cells. Making the batteries with recycled metals could decrease their CO2 footprint by around 25 percent, according to BASF.

Additionally, BASF and Nanotech Energy will also work with the American Battery Technology Company (ABTC) and the Canada-based TODA Advanced Materials Inc. ABTC will recycle the materials gathered by Nanotech, such as nickel, cobalt, manganese, and lithium. TODA will then use the materials to create battery precursors, which BASF will then convert into cathode active materials.

4 Reasons Why Becoming a Type 2 Civilization Is a Bad Idea

Posted by in categories: asteroid/comet impacts, energy, existential risks, military

The year one hundred two thousand twenty-three. A giant meteorite the size of Pluto is approaching the Solar System. It flies straight to Earth. But as the meteorite crosses Saturn’s orbit, a swarm of miner probes approaches it. The scan revealed no minerals on the object, so the searches returned with nothing.

Meanwhile, the Space Security Center in Alaska military personnel are setting up a laser. The Solar System witnesses a sudden flare and nothing remains of the dwarf-sized meteorite. Now, unless hydrogen miners on Jupiter post videos of another annihilation on social media… This is what the world will look like when humanity finally becomes a Type Two civilization on the Kardashev scale. We’ll have almost infinite energy reserves, the ability to prepare for interstellar flights, or to instantly destroy any threat. But will humanity really be safe? And what can ruin a Type Two civilization?

NASA Rover Makes Enough Breathable Oxygen on Mars to Sustain a Dog for 10 Hours

Posted by in categories: energy, space

NASA’s Perseverance rover has successfully completed an experiment designed to create oxygen on Mars, using a technique that could one day provide astronauts with breathable air, and be used as a key ingredient in rocket fuel for a return journey home.

Humanity is looking to expand deeper into the solar system, first by establishing a permanent base on the Moon, before finally placing human boots on Mars for the first time in our species’ short history. For this to be a reality, both NASA and its partners need to develop new technologies that will make use of the natural resources of those distant worlds to ensure that future missions are as self reliant as possible.

One major problem faced by astronauts visiting Mars is ensuring they have a ready supply of breathable air. Oxygen on Earth is relatively abundant, making up roughly 21 percent of our planet’s atmosphere. However, the gasseous shell enveloping Mars is composed of less than one percent oxygen, and 96 percent carbon dioxide, with nitrogen, argon, and other myriad trace gases making up the remainder.

Mysterious ultra-high energy source investigated by astronomers

Posted by in categories: energy, space

Astronomers from the University of Maryland and the Michigan Technological University, have inspected a mysterious ultra-high energy gamma-ray source known as LHAASO J2108+5157. Results of the study, published August 31 on the pre-print server arXiv, could help us unveil the true nature of this source.

Sources emitting with photon energies between 100 GeV and 100 TeV are called very-high energy (VHE) gamma-ray sources, while those with above 0.1 PeV are known as ultra-high energy (UHE) . The nature of these sources is still not well understood; therefore, astronomers are constantly searching for new objects of this type to characterize them, which could shed more light on their properties in general.

A team of astronomers led by University of Maryland’s Sajan Kumar decided to take a closer look at one such UHE gamma-ray source designated LHAASO J2108+5157. It is a point-like source with an extension less than 0.39 degrees, known to be associated with the [MML2017]4607—located some 10,700 away.

Scientists develop an energy-efficient wireless power and information transfer system

Posted by in categories: energy, internet

Industrial Internet of Things (IIoTs) refers to a technology that combines wireless sensors, controllers, and mobile communication technologies to make every aspect of industrial production processes intelligent and efficient. Since IIoTs can involve several small battery-driven devices and sensors, there is a growing need to develop a robust network for data transmission and power transfer to monitor the IIoT environment.

In this regard, is a promising technology. It utilizes to power small devices that consume minimal power. Recently, simultaneous wireless information and power transfer (SWIPT), which utilizes a single radio frequency signal to simultaneously perform and information decoding, has attracted significant interest for IIoTs.

Additionally, with smart devices rapidly growing in number, SWIPT has been combined with nonorthogonal multiple access (NOMA) system, which is a promising candidate for IIoTs due to their ability to extend the battery life of sensors and other devices. However, the energy efficiency of this system falls significantly with transmission distance from the central controller.

Research team develops 2-liter class hydrogen engine capable of running entirely on hydrogen

Posted by in categories: energy, transportation

Amid the fierce competition throughout the globe to develop hydrogen mobility technologies to achieve carbon neutrality, a new technology for a 2-liter class hydrogen-fueled engine (a passenger car hydrogen engine) capable of running entirely on hydrogen has been developed for the first time in Korea.

The joint research team led by Principal Researcher Young Choi of the Department of Mobility Power Research of the Korea Institute of Machinery and Materials (KIMM), and Researcher Hong-gil Baek of the Zero-Carbon Engine Research Lab of Hyundai-Kia Motor Company (HMC) developed the “direct injection hydrogen engine” that runs entirely on hydrogen fuels, and demonstrated its world-class excellence through performance evaluation.

The joint research team of KIMM and HMC injected hydrogen directly into the combustion chamber of the engine of HMC’s existing hybrid vehicle, with a pressure of more than 30 bar. By using a turbo charger that improves the performance of the engine, the research team was able to maintain high thermal efficiency in all domains from the ignition of the engine to the upper limit of the engine load, allowing the engine to be stably operated throughout the entire engine operating conditions.
