By synthesizing novel material for electrode that facilitates reversing of the chemistry of ions, a group of researchers combat the wasteful aspects of energy sources by laying an important foundation for the production of next-generation rechargeable magnesium secondary batteries.
After years of working on an organic aqueous flow battery, researchers found that their ground-breaking, organic anthraquinone molecules were decomposing over time, reducing the long-term usefulness of the battery. Now, the researchers have not only learned how the molecules are decomposing but also how to reverse it. The team’s rejuvenation method cuts the capacity fade rate of the battery a factor of 40 while keeping the cost of the battery low.
Advancements in zero-emission fuel cells could make the technology cheap enough to replace traditional gasoline engines in vehicles.
Engineers continually pioneer new ways to improve battery technology. Scientists recently developed a material which could significantly extend the life of batteries and afford them higher capacities as well.
Scientists have discovered that caffeine can help make a promising alternative to traditional solar cells more efficient at converting light to electricity. Their research may enable this cost-effective renewable energy technology to compete on the market with silicon solar cells.
Solar power researchers have traditionally used the power measurements from single residential solar photovoltaic systems to estimate the power generated within a city. But one installation isn’t a good representation of all rooftops. Data from systems across a city is desperately needed to fully understand how this energy source can be integrated into the power grid. Engineers have provided a freely available quality-controlled and tuned dataset from 1,287 residential installations across Australia.
Improvements to a class of battery electrolyte first introduced in 2017 — liquefied gas electrolytes – could pave the way to a high-impact and long-sought advance for rechargeable batteries: replacing the graphite anode with a lithium-metal anode.
To better analyze the causes of malfunctions and premature failure of lithium batteries, researchers have developed a technique that visualizes the distribution of active lithium on the anode and differentiates between dendrites and ‘dead’ lithium.
An international team of researchers has discovered a new material made from manganese hydride that would be used to make molecular sieves within fuel tanks – which store the hydrogen and work alongside fuel cells in a hydrogen powered ‘system’. The material would enable the design of tanks that are far smaller, cheaper, more convenient and energy dense than existing hydrogen fuel technologies, and significantly out-perform battery-powered vehicles.
Researchers have built a more efficient, more reliable potassium-oxygen battery, a step toward a potential solution for energy storage on the nation’s power grid and longer-lasting batteries in cell phones and laptops.
