Published Chloride ions from seawater eyed as possible lithium replacement in batteries of the future
(via sciencedaily.com) Sodium, Potassium and zinc have all been promising contenders for lithium's place in rechargeable batteries of the future, but researchers have added an unusual and more abundant competitor to the mix: chloride, the richest negatively charged ions in seawater. Xiaowei Teng, the James H. Manning professor of Chemical Engineering at WPI, has discovered a new redox chemistry empowered by chloride ions for the development of seawater green batteries.
Published Faster thin film devices for energy storage and electronics
(via sciencedaily.com) An international research team reported the first realization of single-crystalline T-Nb2O5 thin films having two-dimensional (2D) vertical ionic transport channels, which results in a fast and colossal insulator-metal transition via Li ion intercalation through the 2D channels.
Published Cracking in lithium-ion batteries speeds up electric vehicle charging
(via sciencedaily.com) Rather than being solely detrimental, cracks in the positive electrode of lithium-ion batteries reduce battery charge time, research shows. This runs counter to the view of many electric vehicle manufacturers, who try to minimize cracking because it decreases battery longevity.
Published Energy-storing supercapacitor from cement, water, black carbon
(via sciencedaily.com) Engineers have created a 'supercapacitor' made of ancient, abundant materials, that can store large amounts of energy. Made of just cement, water, and carbon black (which resembles powdered charcoal), the device could form the basis for inexpensive systems that store intermittently renewable energy, such as solar or wind energy.
Published Solar batteries: New material makes it possible to simultaneously absorb light and store energy
(via sciencedaily.com) Researchers are making progress on the design of a solar battery made from an abundant, non-toxic and easily synthesized material composed of 2D carbon nitride.
Published Going the distance for better wireless charging
(via sciencedaily.com) Accounting for radiation loss is the key to efficient wireless power transfer over long distances.
Published Aluminum materials show promising performance for safer, cheaper, more powerful batteries
(via sciencedaily.com) Researchers are using aluminum foil to create batteries with higher energy density and greater stability. The team's new battery system could enable electric vehicles to run longer on a single charge and would be cheaper to manufacture -- all while having a positive impact on the environment.
Published Current thinking on batteries overturned by cathode oxidation research
(via sciencedaily.com) Scientists have made a significant breakthrough in understanding and overcoming the challenges associated with Ni-rich cathode materials used in lithium-ion batteries.
Published Dry manufacturing process offers path to cleaner, more affordable high-energy EV batteries
(via sciencedaily.com) Early experiments have revealed significant benefits to a dry battery manufacturing process. This eliminates the use of toxic solvents while showing promise for delivering a battery that is durable, less weighed down by inactive elements and able to maintain high energy storage capacity after use. Such improvements could boost wider EV adoption, helping to reduce carbon emissions and achieve U.S. climate goals.
Published Next-generation flow battery design sets records
(via sciencedaily.com) A new flow battery design achieves long life and capacity for grid energy storage from renewable fuels.
Published New design rule for high-entropy superionic solid-state conductors
(via sciencedaily.com) Solid electrolytes with high lithium-ion conductivity can be designed for millimeter-thick battery electrodes by increasing the complexity of their composite superionic crystals, report researchers from Tokyo Tech. This new design rule enables the synthesis of high-entropy active materials while preserving their superionic conduction.
Published Public support hydrogen and biofuels to decarbonize global shipping
(via sciencedaily.com) Original source New research into public attitudes towards alternative shipping fuels shows public backing for biofuel and hydrogen. The study also found that nuclear was preferred to the heavy fuel oil (HFO) currently used in the global shipping industry, although both were perceived negatively. Ammonia had the least public support.
Published Nanosheet technology developed to boost energy storage dielectric capacitors
(via sciencedaily.com) A research group has used nanosheet technology to develop a dielectric capacitor for advanced electronic and electrical power systems.
