What if the future of energy storage wasn’t just an incremental improvement but a complete reimagining? Solid-state batteries, long considered the holy grail of energy technology, could be the key to unlocking safer, faster, and more sustainable power solutions. In this guide, Ziroth explores how Donut Lab’s bold claim of creating the world’s first solid-state battery could transform industries like electric vehicles (EVs) and renewable energy. But with skepticism swirling around untested prototypes and ambitious performance metrics, the question remains: is this breakthrough the real deal or just another overhyped promise? This investigation dives into the fascinating claims surrounding Donut...

DGIST researchers developed a nitrogen-doped carbon material to boost the performance of lithium–sulfur batteries, achieving faster charging, improved capacity, and long-term stability, paving the way for their commercialization. Professor Jong-sung Yu’s team developed a nitrogen-doped porous carbon material that boosts lithium–sulfur battery performance, achieving rapid charging (12 minutes) and long-term stability (82% capacity retention after 1,000 cycles). This breakthrough could accelerate battery commercialization. A research team led by Professor Jong-sung Yu from the DGIST Department of Energy Science and Engineering, under President Kunwoo Lee, has developed a groundbreaking technology to dramatically improve the charging speed of lithium-sulfur batteries. The team...

Korean researchers have developed advanced Ni-rich cathodes that improve all-solid-state battery performance, offering longer lifespans and greater energy efficiency. n an era where electronic devices and electric vehicles demand better battery performance, scientists are racing to develop batteries that last longer, charge faster, and store more energy. A promising solution lies in all-solid-state batteries (ASSBs), which could outperform traditional lithium-ion batteries in both efficiency and safety. At the heart of this innovation is the cathode active material (CAM), particularly those rich in nickel (Ni), which plays a crucial role in boosting battery performance. Role of Ni-rich cathodes ASSBs differ from...

Chery Automobile, a Chinese automaker, recently released a prototype solid-state battery that offers double the energy density of current EV batteries. Here’s what you’ll learn when you read this story. * Solid-state batteries are the next quantum leap for EVs, unlocking more range, performance, and longevity. * Chery Automobile’s prototype battery module boasts a 600 Wh/Kg energy density—double the energy density of most current EV batteries. * Chery’s new battery is also puncture-resistant, significantly reducing the risk of fire should any of the cells be damaged. ============================================== Energy density is the latest hot pursuit for unlocking more range and performance...

Ask someone who drives a gasoline-powered car why they wouldn't want to get an electric one, and you're almost certain to hear this answer: they take way too long to charge. They're not even entirely wrong. Even though DC fast charging times are getting shorter and shorter for modern electric vehicles, they can seem totally unacceptable for anyone who's used to fueling a gas-powered car in a matter of minutes—and that still describes most people in this country. To counter this, the Chinese carmaking giant BYD, which recently surpassed Tesla in EV sales, came up with an idea so ambitious...

A lithium-air battery that rivals gasoline in energy density may be the game-changer EVs have been waiting for. ================================================================= In a major leap toward next-generation energy storage, researchers have created a lithium-air battery that could one day rival gasoline in energy density, offering up to four times the capacity of today’s lithium-ion batteries. If realized at scale, such a breakthrough could transform everything from electric vehicles to grid storage. This cutting-edge development, led by scientists at the Illinois Institute of Technology and Argonne National Laboratory, hinges on achieving a four-electron chemical reaction—a feat never before accomplished in a lithium-air battery...

(Kitco News) – Gold has had a breakout year as the yellow metal surged to new heights above $2,500 while its grey counterpart, silver, has struggled to keep pace, but that could soon change, according to one analyst, as silver demand is expected to increase thanks to one new technological development from Samsung. According to retired investment professional Kevin Bambrough, Samsung has developed a new solid-state (SS) battery. The inclusion of silver as a key component, combined with the increasing demand for electric vehicles, means that demand for the grey metal will soon increase. “The key drivers that will ramp...

A new nickel-rich, single-crystal battery technology is on track for rapid deployment A seemingly simple shift in lithium-ion battery manufacturing could pay big dividends, improving electric vehicles’ (EV) ability to store more energy per charge and to withstand more charging cycles, according to new research led by the Department of Energy’s Pacific Northwest National Laboratory. An EV’s mileage depends on the deliverable energy from each of the constituent cells of its battery pack. For lithium-ion cells—which dominate the EV battery market—both the cell-level energy capacity and the cell cost are bottlenecked by the positive electrode, or cathode. Now that bottleneck...

Donut Lab commissioned VTT to validate its bold solid-state claims, and the results show near-full capacity retention even after ultra-fast charging... Rapid charging under test VTT Technical Research Centre ran the tests in what engineers described as a worst-case scenario. The lab did not use active temperature controls. It also let the cell’s heat rise freely at high charging rates. Experts measured performance using C-rates, where 1C equals a one-hour charge from empty to full. Under that scale, 5C roughly equals a 12-minute charge, and 11C is about a five- to six-minute charge. The process began with a standard discharge...
