Silicon Solves Problems for Next-Gen Battery Tech: University of Eastern Finland

Published

on

Silicon – the second most abundant element in the earth’s crust – shows great promise in Li-ion batteries, according to new research from the University of Eastern Finland. By replacing graphite anodes with silicon, it is possible to quadruple anode capacity.

In a climate-neutral society, renewable and emission-free sources of energy, such as wind and solar power, will become increasingly widespread. The supply of energy from these sources, however, is intermittent, and technological solutions are needed to safeguard the availability of energy also when it’s not sunny or windy. Furthermore, the transition to emission-free energy forms in transportation requires specific solutions for energy storage, and lithium-ion batteries are considered to have the best potential.

Researchers from the University of Eastern Finland introduced new technology to Li-ion batteries by replacing graphite used in anodes by silicon. The study analysed the suitability of electrochemically produced nanoporous silicon for Li-ion batteries. It is generally understood that in order for silicon to work in batteries, nanoparticles are required, and this brings its own challenges to the production, price and safety of the material.

However, one of the main findings of the study was that particles sized between 10 and 20 micrometres and with the right porosity were in fact the most suitable ones to be used in batteries. The discovery is significant, as micrometre-sized particles are easier and safer to process than nanoparticles. This is also important from the viewpoint of battery material recyclability, among other things. The findings were published in Scientific Reports.

“In our research, we were able to combine the best of nano- and micro-technologies: nano-level functionality combined with micro-level processability, and all this without compromising performance,” Researcher Timo Ikonen from the University of Eastern Finland says. “Small amounts of silicon are already used in Tesla’s batteries to increase their energy density, but it’s very challenging to further increase the amount,” he continues.

Next, researchers will combine silicon with small amounts of carbon nanotubes in order to further enhance the electrical conductivity and mechanical durability of the material. “We now have a good understanding of the material properties required in large-scale use of silicon in Li-ion batteries. However, the silicon we’ve been using is too expensive for commercial use, and that’s why we are now looking into the possibility of manufacturing a similar material from agricultural waste, for example from barley husk ash,” Professor Vesa-Pekka Lehto explains.

Lamborghini Announces the New Urus S

Published

on

Automobili Lamborghini has announced the Urus S: the successor to the original Urus that established a new Super SUV niche in the luxury segment. The Urus S delivers increased power combined with luxurious versatility and presence to confirm its status as the ultimate lifestyle Lamborghini Super SUV, alongside the new Urus Performante for those seeking maximum sports performance.

“The Urus has proven its appeal for those seeking the decisive combination of the sportiest SUV and a Lamborghini to drive every day: the Urus S sits perfectly alongside the new Urus Performante, for those choosing the purest sublimation of performance, luxury, and versatility,” said Stephan Winkelmann, Chairman, and CEO of Automobili Lamborghini. “The Urus’ commercial success, with more than 20,000 vehicles produced, is testament to its credentials as the first and enduring Super SUV: the Urus S elevates that reputation.”

The twin-turbo V8 engine with increased power to 666 CV matches that of the Urus S’ Performante stablemate, delivering an improved weight-to-power ratio of 3.3 kg/CV. Acceleration is improved, with the Urus S propelling from 0-100 km/h in 3.5 seconds and 0-200 km/h in 12.5 seconds. With a top speed of 305 km/h, the Urus S brakes from 100 km/h back to zero in just 33.7m.  Its twin-turbo engine delivers 850 Nm of maximum torque already at 2,300 rpm up to a maximum 6,000 rpm. A retuned exhaust system reminds us that the Super SUV is a true Lamborghini, with a more distinct sound at start-up and a sharper note in each drive mode.

The Urus’ chassis with adaptive air suspension ensures super sports driving enjoyment but smooth handling on road surfaces, with immediately-available torque response and body balancing according to the particular requirements of its off-road drive selectors.  With the same powertrain calibration as the Urus Performante, the Urus S delivers optimum responsiveness and performance when required, alongside luxurious everyday driving pleasure from the Urus’ finely-tuned chassis settings.

The Urus S introduces specific and sophisticated design enhancements advocating its sporty but luxurious lifestyle persona, distinguishing the Super SUV’s presence in every environment. The interior of the Urus S is presented with a fully-revised color and trim offer. Both the new Bi-color Sportivo and a new Bi-color Sophisticated option feature the new Urus Performante stitching pattern.

The Bi-color Sportivo delivers a more discreet and stylish use of the complementary color; the Sophisticated black leather trim comes with new contrast color options in conjunction with refined new Blu Leandro and Verde Aura alongside tan, cream, and brown. Providing optimum opportunities for owners to specify their Urus S according to their lifestyle, the new color and trim options underline the high-performance credentials of the Urus S while delivering understated and timeless luxury.
