One of the biggest upcoming challenges for electric cars is having an adequate supply of lithium batteries.A new report by Benchmark Minerals, first cited by CleanTechnica, shows battery makers are working quickly to meet growing demand for new lithium-ion battery cells from automakers.solar street light lithium battery
According to the company's Battery Factory Data, battery suppliers ramped up their forecast supply from 922 gigawatt-hours in 2023 to 965 in February, an increase of 4 percent in February alone. Extrapolated to an annualized forecast, that would increase battery supplies available in that year by 50 percent this year alone.It's unclear, of course, whether growth in supply forecasts will continue soaring on that trajectory for the rest of the year, but constraints in battery supplies have already emerged as a likely obstacle to planned electric-car production by the middle of the next decade.
The Volkswagen Group alone has ramped up its investment in developing future electric cars to $50 billion by 2023. Other automakers including BMW, Daimler (Mercedes-Benz), General Motors, and Fiat Chrysler.So far, most electric car batteries have come from just a handful of suppliers, including Korean LG Chem, Nissan's SAIC, CATL, Panasonic (for Teslas), Samsung, and SK Innovation.
That has left some automakers planning big investments in electric cars at the mercy of battery suppliers and led to delays in some products and likely to lower production of some models than the automakers could sell.
The Benchmark Minerals report shows production capacity for lithium-ion battery growing to almost 1.6 terawatt-hours by 2028.
I’m not sure how we missed it, but in May, the inventor of the lithium-ion battery received the Royal Society’s prestigious Copley Medal.
Professor John Goodenough from the Cockrell School of Engineering at The University of Texas at Austin received the medal, the world’s oldest scientific prize. Already a fellow of the Royal Society, Goodenough was honored for his exceptional contributions to materials science, especially his discoveries that led to the invention of the rechargeable lithium battery. In case you’ve been living under a rock, lithium-ion batteries are a big part of the re-emergence of electric vehicles, improvement of grid storage, and the compact size of smartphones — all things that have made immeasurable impacts and will continue to.Lithium Battery Cell voltage
Venki Ramakrishnan, President of the Royal Society, said, “Professor Goodenough has a rich legacy of contributions to materials science in both a fundamental capacity, with his defining work on the properties of magnetism, to a widely applicable one, with his ever-advancing work on batteries, including those powering the smartphone in your very pocket. The Royal Society is delighted to recognise his achievements with the Copley Medal, our most prestigious prize.”
Over decades, the professor has worked on a variety of projects that have had big impacts, including work that led to the invention of Random Access Memory, or RAM, an critical component in modern computing. Professor Goodenough continues to work on new battery technology at UT Austin. Though his lithium-ion breakthrough provided a reliable, rechargeable battery, there are still shortcomings that Professor Goodenough aims to overcome with his latest work on solid-state batteries.The Copley Medal was first awarded by the Royal Society in 1731, 170 years before the first Nobel Prize. As the latest recipient of the Royal Society’s premier award, Professor Goodenough joins an elite group of men and women, such as Benjamin Franklin, Charles Darwin, Louis Pasteur, Albert Einstein, and Dorothy Hodgkin, who have been awarded the Copley Medal for their exceptional contributions to science and engineering in the past. In recent years, recipients include eminent scientists such as Peter Higgs, the physicist who hypothesized the existence of the Higgs Boson, as well as DNA fingerprinting pioneer Alec Jeffreys, and Andre Geim, who discovered graphene. Last year’s winner, Professor Jeffrey Gordon, was honored for his contributions to understanding the role of gut microbial communities to human health and disease.
Video It's never easy to crack into a market with an innovative new product but makers of the "world's first smart fingerprint padlock" have made one critical error: they forgot about the existence of screwdrivers.Electric Cabinet Lock manufacturers
Tapplock raised $320,000 in 2016 for their product that would allow you to use just your finger to open the "unbreakable" lock. Amazing. Things took a turn for the worse when the ship date of September came and went, and backers complained that the upstart has stopped posting any updates and wasn't responding to emails nor social media posts.
But after months of silence, the startup assured El Reg that everything was still moving forward and the delays were due to "issues with manufacturing in China."
Fast forward 18 months and finally – finally – the $100 Tapplock is out on the market and it is… well, how do we put this kindly? Somewhat flawed.
No less than three major problems with the lock have been discovered that make it less than useless because presumably people intend to use the lock to secure valuable things.
One of the first things to note is that the Tapplock used zinc aluminum alloy Zamak 3: something that it claims lends the lock "unbreakable durability." Unfortunately, as materials engineers are happy to point out, aluminum may be a lovely lightweight metal and this alloy does provide an enviable degree of detail when die cast, but it is not exactly the best choice for something that is supposed to be unbreakable.
It isn't very strong, it melts at high temperatures, and it is quite brittle. It looks cool. But it's more suited for its more common use: door handles. It will be easy to cut through this lock with bolt cutters.
