Silicon-carbon batteries as an alternative to Li-Ion and Li-Pol in smartphones
The mobile gadget market is developing rapidly every year. Cameras are improving, more powerful processors are being offered, artificial intelligence functions are being introduced, and so on. However, reliable batteries with fast charging cycles and high capacity remain one of the main requirements from users. And while most smartphones still use…
Li-Ion batteries degrade even without charging — scientists have discovered this and found a solution
Scientists from Pohang University of Science and Technology in South Korea have discovered a previously unknown The mechanism of degradation of lithium-ion batteries in the process of using them.
Just a hype: Solid-state lithium-metal batteries disappoint researchers
Scientists dispelled expectations about the prospects use of solid-state lithium-metal batteries lithium-lanthanum-zirconium oxide (LLZO) batteries, which were expected to become a promising replacement for traditional lithium-ion batteries.
Fallout is coming: new nuclear batteries are safe and last for decades
Professor Suh-Il In from Daegu Kyungbuk Institute of Science and Technology presented a prototype of a radiocarbon nuclear battery as an alternative to lithium-ion batteries.
Lithium mining is rapidly depleting South America’s water reserves, — study
Scientists from the University of Massachusetts at Amherst have found in a new study, that freshwater reserves in the so-called «lithium triangle» in South American countries are 10 times smaller than previously thought.
Anker recalls its Bluetooth speakers due to fire hazard
Manufacturer Anker is recalling nearly 80,000 Soundcore and PowerConf Bluetooth speakers. Lithium batteries in some of them overheated and caught fire.
A breakthrough in lithium-ion batteries: 98% capacity retention after 500 cycles, lower cost and increased thermal stability
Scientists at Argonne National Laboratory have developed a new dual-gradient design for cathodes that promises to significantly improve lithium-ion battery performance and reduce costs. This could potentially accelerate the introduction of electric vehicles and grid energy storage.
Airplane evacuated in the US due to laptop fire — there are injured
A laptop caught fire on an American Airlines passenger plane, prompting an emergency evacuation of passengers. Flight 2045 was preparing to depart from San Francisco to Miami when smoke filled the cabin.
Lithium-ion batteries are a source of dangerous pollution «with everlasting chemicals», researchers say
Some lithium-ion battery manufacturing technologies use a class of chemicals called PFAS (per- and polyfluoroalkyl substances). They help make batteries less prone to fire and increase their conductivity. However, they also pose great environmental and health risks.
