Toyota tempers expectations for solid-state battery adoption

Posted by in categories: chemistry, sustainability, transportation

It really is impressive how many unknowns there are about the next decade in transportation. Sure, there have always been innovations and surprises, but to be unsure what most vehicles will even be powered by in 10 years, nor who — or what — will be in the driver’s seat, is astounding. Battery-electric vehicles are the leading contender to usurp internal combustion, eventually, though the road to that outcome is full of hurdles. Solid-state batteries (SSB) are seen as one of the key innovations to get there, various makers saying they’ll have at least one product with a solid-state battery on the market by the end of the decade. The overall numbers of SSB-powered vehicles might remain surprisingly low well into the 2030s, though. In Toyota’s internal news outlet, Toyota Times, the automaker wrote, “In the [SSB] mass production phase anticipated for 2030 and beyond, the companies are looking to boost capacity to several thousand tonnes (several tens of thousands of vehicles) in line with Toyota’s product plans.”

The “companies” referred to are Toyota and Japan’s petrochemical conglomerate Idemitsu Kosan, which formalized collaboration on SSBs this year. Right now, Toyota and Idemitsu are working on the development times for solid electrolyte and resulting quality and cost. When those are locked in, the firms will work on a pilot facility for commercialization. Initial commercial effort will take two years of testing and validation before wider production commences in 2030.

The “several tens of thousands of vehicles” appears to have gone through at least one revision after publication. In Jalopnik’s writeup, the capacity was quoted as “over ten thousand vehicles.” Even at the larger sum, that’s considerably less than onlookers expected, but that might be because onlookers expected too much, not because Toyota overpromised. The automaker’s talked big numbers for BEV sales, but has talked just as bigly about what kinds of electrified powertrains those sales will entail: At least four kinds of battery technologies, plus hydrogen, and hybrids. In 2021, Toyota said it expected to have an SSB ready by 2025. In 2022, a Toyota engineer said the first product to get an SSB would be a hybrid on go on sale in the first half of the decade.

Chery and Huawei brand Luxeed shakes up EV market with 855 km range S7, starting at $35k

Posted by in categories: sustainability, transportation

Luxeed – a young, premium EV brand developed between Chery Automobile and Chinese tech giant Huawei, has shared new details of its flagship sedan, the S7. In a matter of months since first teasing the Tesla Model S competitor, followed by an influx of pre-orders, Chery and Huawei have now shared trim variants, pricing, and of course, range – which tops out at an impressive 855 km.

Luxeed is a new all-electric brand in China and when we say “new,” we mean we didn’t even know the official name of the joint effort between China’s Chery and Huawei until about four months ago.

In that time, we’ve seen Huawei tease its first model, learned its core specs from a regulatory filing in China, and saw the S7 sedan’s first unveiling three weeks ago, ahead of an official launch that took place today.

Tesla Cybertruck delivery event: everything Elon revealed about the EV pickup

Posted by in categories: Elon Musk, media & arts, sustainability, transportation

With dubstep as the soundtrack and neon lighting as the backdrop, Elon Musk handed the first Cybertrucks over to a select group of customers that included Reddit co-founder and VC fund Seven Seven Six founder Alexis Ohanian and Trousdale Ventures founder and CEO Phillip Sarofim.

The live streamed portion of the Tesla Cybertruck delivery event was a short affair — around 30 minutes. But the event still had all the traditional trappings one has come to expect from Tesla: the pomp and pumpy music, VIP guests and of course, Musk.

The Tesla Cybertruck deliveries come at least six years since Musk first tweeted about building a truck and four years since he debuted the futuristic-looking pickup.

Google DeepMind researchers use AI tool to find 2mn new materials

Posted by in categories: robotics/AI, solar power, sustainability

Google DeepMind researchers have discovered 2.2mn crystal structures that open potential progress in fields from renewable energy to advanced computation, and show the power of artificial intelligence to discover novel materials.

The trove of theoretically stable but experimentally unrealised combinations identified using an AI tool known as GNoME is more than 45 times larger than the number of such substances unearthed in the history of science, according to a paper published in Nature on Wednesday.

The researchers plan to make 381,000 of the most promising structures available to fellow scientists to make and test their viability in fields from solar cells to superconductors. The venture underscores how harnessing AI can shortcut years of experimental graft — and potentially deliver improved products and processes.

An #AI tool that has discovered 2.2 million new materials, and helps to predict material stability.


AI tool GNoME finds 2.2 million new crystals, including 380,000 stable materials that could power future technologies.

Modern technologies from computer chips and batteries to solar panels rely on inorganic crystals. To enable new technologies, crystals must be stable otherwise they can decompose, and behind each new, stable crystal can be months of painstaking experimentation.

Inverted Perovskite Solar Cell Breaks 25% Efficiency Record

Posted by in categories: particle physics, solar power, sustainability

Northwestern University researchers have raised the standards again for perovskite solar cells with a new development that helped the emerging technology hit new records for efficiency.

The findings, published today (Nov. 17) in the journal Science, describe a dual-molecule solution to overcoming losses in efficiency as sunlight is converted to energy. By incorporating first, a molecule to address something called surface recombination, in which electrons are lost when they are trapped by defects—missing atoms on the surface, and a second molecule to disrupt recombination at the interface between layers, the team achieved a National Renewable Energy Lab (NREL) certified efficiency of 25.1% where earlier approaches reached efficiencies of just 24.09%.

“Perovskite solar technology is moving fast, and the emphasis of research and development is shifting from the bulk absorber to the interfaces,” said Northwestern professor Ted Sargent. “This is the critical point to further improve efficiency and stability and bring us closer to this promising route to ever-more-efficient solar harvesting.”

Electrochemical C–N Bond Formation within Boron Imidazolate Cages Featuring Single Copper Sites

Posted by in categories: chemistry, energy, sustainability

Electrocatalysis expands the ability to generate industrially relevant chemicals locally and on-demand with intermittent renewable energy, thereby improving grid resiliency and reducing supply logistics. Herein, we report the feasibility of using molecular copper boron-imidazolate cages, BIF-29(Cu), to enable coupling between the electroreduction reaction of CO2 (CO2RR) with NO3– reduction (NO3RR) to produce urea with high selectivity of 68.5% and activity of 424 μA cm–2. Remarkably, BIF-29(Cu) is among the most selective systems for this multistep C–N coupling to-date, despite possessing isolated single-metal sites. The mechanism for C–N bond formation was probed with a combination of electrochemical analysis, in situ spectroscopy, and atomic-scale simulations. We found that NO3RR and CO2RR occur in tandem at separate copper sites with the most favorable C–N coupling pathway following the condensation between *CO and NH2OH to produce urea. This work highlights the utility of supramolecular metal–organic cages with atomically discrete active sites to enable highly efficient coupling reactions.

Toyota CEO: “Our Ammonia Engine Is the End of EV’s”

Posted by in categories: energy, sustainability, transportation

In a world that seems inexorably drawn towards an all-electric future, Toyota has consistently taken a different road. The Japanese automaker remains skeptical about an exclusive reliance on electric vehicles (EVs). While it’s true that Toyota has some exciting EVs in the pipeline for the upcoming year, they are also actively exploring alternative energy sources. However, a recent development could potentially turn the tables on the EV revolution — an ammonia-powered engine for passenger vehicles.
