Lithium (Li) ions are central to the energy storing functionality of rechargeable batteries1. Present technology relies on sophisticated Li-inclusive electrode materials to provide Li ions and exactingly protect them to ensure a decent lifetime2. Li-deficient materials are thus excluded from battery design, and the battery fails when active Li ions are consumed3. Our study breaks Read more about External Li supply reshapes Li deficiency and lifetime limit of batteries[…]

[…] new research suggests these batteries, once thought to have short-lived, inherently  expendable shelf-lives, may actually last significantly longer than expected. In some cases, properly cared for EVs may even outlive their fossil fuel counterparts. That’s potentially good news: longer-lasting EVs might buy manufacturers much-need time to fabricate components needed to meet increasing global demands. Read more about Surprise: EV batteries might have a longer shelf live than once thought[…]

The UK Atomic Energy Authority (UKAEA) and the University of Bristol have built a diamond battery capable of delivering power, albeit a tiny amount, for thousands of years. The university had an idea for a battery powered by carbon-14, the longest-lived radioactive isotope of carbon with a half-life of around 5,700 years. For safety reasons, Read more about Boffins build diamond battery that lasts millennia[…]

Oxford University scientists may have solved one of the greatest hindrances of expanding access to solar energy. Scientists from the university’s physics department have created an ultra-thin layer of material that can be applied to the exterior of objects with sunlight access in place of bulky silicon-based solar panels. The ultra-thin and flexible film is Read more about Oxford scientists’ new light-absorbing material can turn everyday objects into solar panels[…]

“Nature recently published an open-access article (not paywalled) that studies the lifecycle of lithium-ion batteries once they are manufactured,” writes Slashdot reader NoWayNoShapeNoForm. “The study is a ‘cradle-to-grave’ look at these batteries and certain chemicals that they contain. The University researchers that authored the study found that the electrolytes and polymers inside lithium-ion batteries contain Read more about Lithium Ion Batteries a Growing Source of PFAS Pollution, Study Finds[…]

[…] “Although there have been previous sodium, solid-state, and anode-free batteries, no one has been able to successfully combine these three ideas until now,” said UC San Diego PhD candidate Grayson Deysher, first author of a new paper outlining the team’s work. The paper, published today in Nature Energy, demonstrates a new sodium battery architecture Read more about A breakthrough in solid state sodium batteries: inexpensive, clean, fast-charging[…]

A battery’s best friend is a capacitor. Powering everything from smartphones to electric vehicles, capacitors store energy from a battery in the form of an electrical charge and enable ultrafast charging and discharging. However, their Achilles’ heel has always been their limited energy storage efficiency. Now, Washington University in St. Louis researchers have unveiled a Read more about Capacitor Breakthrough: 19-Fold Increase in Energy Storage Potential – could kill batteries[…]

Windows welcome light into interior spaces, but they also bring in unwanted heat. A new window coating blocks heat-generating ultraviolet and infrared light and lets through visible light, regardless of the sun’s angle. The coating can be incorporated onto existing windows or automobiles and can reduce air-conditioning cooling costs by more than one-third in hot Read more about Window coating blocks sun heat from any angle but not view[…]

[…] an adaptive tile, which when deployed in arrays on roofs, can lower heating bills in winter and cooling bills in summer, without the need for electronics. “It switches between a heating state and a cooling state, depending on the temperature of the tile,” said Xiao, the lead author of the study. “The target temperature Read more about Adaptive wax-motor roof tile can cut both heating and cooling costs[…]

The plane-maker on Thursday revealed it has “commissioned shipowner Louis Dreyfus Armateurs to build, own and operate these new, highly efficient vessels that will enter into service from 2026.” The ships will have conventional engines that run on maritime diesel oil and e-methanol, the latter fuel made with a process that produces less CO2 than Read more about Airbus commissions three wind-powered ships[…]

Heat pumps are more than twice as efficient as fossil fuel heating systems in cold temperatures, research shows. Even at temperatures approaching -30C, heat pumps outperform oil and gas heating systems, according to the research from Oxford University and the Regulatory Assistance Project thinktank. […] The research, published in the specialist energy research journal Joule, Read more about Heat pumps twice as efficient as fossil fuel systems in cold weather, study finds – gas lobby misinforms, blocks uptake[…]

Obtaining useful work from random fluctuations in a system at thermal equilibrium has long been considered impossible. In fact, in the 1960s eminent American physicist Richard Feynman effectively shut down further inquiry after he argued in a series of lectures that Brownian motion, or the thermal motion of atoms, cannot perform useful work.   Now, Read more about Scientists design novel nonlinear circuit to harvest clean power using graphene[…]
