Samsung is reportedly testing silicon-carbon anode batteries for the Galaxy S27 lineup, but higher costs could limit the tech to the S27 Pro and S27 Ultra, meaning the standard S27 and S27+ may not get bigger batteries.
Researchers at Dundee and Warwick universities have shown that oxygen actively participates in energy storage within lithium‑ion battery cathodes, overturning the view that oxygen is passive. By comparing layered oxide cathodes with phosphates and using advanced modeling and experiments, they demonstrate significant oxygen redox in the charging/discharging process. Published in Nature Nanotechnology, the findings could enable batteries that charge faster, last longer, and are safer for electric vehicles and portable electronics.
GM signals a potential shift from lithium-iron-phosphate (LFP) to lithium manganese-rich (LMR) batteries for high-volume EVs, arguing LMR could match LFP’s cost while delivering higher energy density; however, LMR still must prove itself outside the lab before mass production. The Chevy Bolt will keep LFP through 2027, Ford is also pursuing LMR, and GM plans U.S. production of LMR cells by 2028, alongside separate sodium-ion efforts for grid storage.
Mercedes‑AMG’s GT 4‑Door abandons the V8 for a fully electric powertrain, delivering up to 1,153 hp (GT63) and 1,475 lb‑ft, 0–60 mph in 2.0 s, and an estimated 435 miles WLTP range with 600 kW charging. It introduces a new design language inspired by the GT XX concept, adds a frunk, and features a refreshed interior with a dual-screen infotainment setup; GT55/GT63 trims arrive by late 2026, with pricing still undisclosed.
Rumors suggest the Galaxy S27 Ultra will employ silicon-carbon batteries, boosting energy density with potential capacities in the 12,000–18,000 mAh range, enabling longer use between charges. Samsung reportedly targets up to 1,500 charging cycles and improved thermal stability, aided by separator and stacking design tweaks, plus smarter battery management, which could extend device life and push broader adoption of this tech.
Researchers at Tokyo University of Science found that using hard carbon as the anode enables high sodium storage and faster sodiation, potentially matching fast charging of lithium ion batteries and boosting energy density. Sodium ion batteries offer environmental and supply chain advantages, including cheaper production and safer shipping, with growing use in vehicles. However they still lag lithium ion in energy density and face challenges to sustain fast charging due to ion traffic jams, so lithium ion remains dominant for now while sodium ion technology continues to advance.
A six-story science roundup highlights Edison’s revived nickel‑iron battery for rapid recharge (but lower energy density), a star in Andromeda that collapsed directly into a black hole without a supernova, a snap-on ‘smart underwear’ sensor that tracks daily fart frequency, simulations explaining how Kuiper Belt contact binaries form, AI-assisted work proposing a possible ancient Roman board game called Ludos Coriovalli, and DishBrain’s neurons learning to play Doom with a Python-friendly interface.
Donut Lab has introduced the world's first all-solid-state battery for a production vehicle, currently powering Verge Motorcycles' TS Pro electric motorcycle, offering lighter weight, longer lifespan, faster charging, and lower costs, with potential applications in larger vehicles and future electric platforms.
Samsung is preparing to mass-produce solid-state batteries with a 600-mile range that can charge in 9 minutes, aiming for market release next year, in partnership with BMW and Solid Power, promising safer, more efficient energy storage for electric vehicles and devices.
A tech enthusiast compares the Oppo Find X9 Pro with the iPhone 17 Pro Max, highlighting features like superior camera capabilities, larger battery capacity, and additional functionalities that Apple could consider for the upcoming iPhone 18 to stay competitive.
The OnePlus 15 is generating excitement due to its modern flat design, advanced cooling system, upgraded camera, massive 7300mAh silicon-carbon battery, and potential for a competitive price, positioning it as a strong contender to shake up the US smartphone market amidst a landscape of incremental upgrades from Apple, Samsung, and Google.
MIT researchers have developed a new model based on coupled ion-electron transfer (CIET) to better understand how lithium-ion batteries work, which could lead to the design of more powerful and faster-charging batteries by optimizing intercalation processes and electrolyte compositions.
Xiaomi is set to launch its 17, 17 Pro, and 17 Pro Max smartphones in China on September 25, featuring advanced OLED displays with high luminous efficiency, new RGB pixel technology, and upgraded battery systems supporting fast charging, all powered by Snapdragon 8 Elite Gen 5 chipset and running Xiaomi Hyper OS 3.
The iPhone Air features a groundbreaking battery design using patented metal can technology, allowing for a two-dimensional shape that maximizes space and durability. This innovation not only enhances the device's form factor but also paves the way for higher energy density batteries, including the potential adoption of silicon anodes, which could significantly improve battery performance in future electronics.
While global smartphone manufacturers are adopting silicon-carbon batteries to create smaller or more powerful phones, major US companies like Apple, Samsung, and Google have yet to incorporate this technology, leading to a gap in innovation in the US market.
