Published More economical and sustainable rechargeable batteries
(via sciencedaily.com) Original source Lithium salts make batteries powerful but expensive. An ultralow-concentration electrolyte based on the lithium salt LiDFOB may be a more economical and more sustainable alternative. Cells using these electrolytes and conventional electrodes have been demonstrated to have high performance. In addition, the electrolyte could facilitate both production and recycling of the batteries.
Published The biggest barrier to a vibrant second-hand EV market? Price
(via sciencedaily.com) Original source As early adopters of electric vehicles (EVs) trade up for the latest models, the used EV market is beginning to mature in the United States. Yet many potential buyers, particularly low-income drivers, are skeptical of EV's conveniences and are put off by the price.
Published Mess is best: Disordered structure of battery-like devices improves performance
(via sciencedaily.com) Original source The energy density of supercapacitors -- battery-like devices that can charge in seconds or a few minutes -- can be improved by increasing the 'messiness' of their internal structure. Researchers used experimental and computer modelling techniques to study the porous carbon electrodes used in supercapacitors. They found that electrodes with a more disordered chemical structure stored far more energy than electrodes with a highly ordered structure.
Published Neutrons rule the roost for cage-free lithium ions
(via sciencedaily.com) Original source Scientists using neutrons set the first benchmark (one nanosecond) for a polymer-electrolyte and lithium-salt mixture. Findings could boost power and safety for lithium batteries.
Published Pyrite, also known as fool's gold, may contain valuable lithium, a key element for green energy
(via sciencedaily.com) Original source The technology revolution and development of new renewable energy resources is driving demand for lithium to new heights, but it is not a common mineral. Scientists say they have found lithium in an unexpected place; fool's gold, or pyrite, deposits.
Published Discovery brings all-solid-state sodium batteries closer to practical use
(via sciencedaily.com) Original source Researchers have developed a mass synthesis process for sodium-containing sulfides. Mass synthesis of electrolytes with high conductivity and formability is key to the practical use of all-solid-state sodium batteries, thought to be safer than lithium-ion batteries and less expensive, as sodium is far more plentiful than lithium.
