An algorithm can monitor the health of retired vehicle batteries used to store surplus power fed into the electrical grid.
The natural vein structure found within leaves—which has inspired the structural design of porous materials that can maximize mass transfer—could unlock improvements in energy storage, catalysis, and sensing thanks to a new twist on a century-old biophysical law.
Hydrogen energy is considered a promising solution with high energy density and zero pollution emissions. Currently, hydrogen is mainly derived from fossil fuels, which increases energy consumption and greenhouse gas emissions, hindering efforts to achieve carbon neutrality goals.

Each year the average American consumes more than 23 barrels of petroleum products. What does a lifetime of fossil fuel consumption look like?
Researchers used X-ray diagnostics for deeper plasma temperature insights.
The fusion reaction plasma carried 15 percent more energy and had twice the density than before, the researchers said.
Researchers in China have developed a water-based battery, which is claimed to be much safer and energy-efficient than “highly flammable” non-aqueous lithium batteries.
Interestingly, the researchers say that these new batteries will be twice as energy-dense as traditional lithium-ion options. This holds the potential to revolutionize the electric vehicle industry.
Moreover, aqueous batteries use water as the solvent for electrolytes, enhancing their safety. Traditional non-aqueous lithium-ion batteries have a high energy density, but their safety is compromised due to the flammable organic electrolytes, a component that allows the battery to charge and discharge, they utilize.
Astronomers still don’t know what causes fast radio bursts, but they’re starting to use them to illuminate the space between galaxies.
Traditional lithium-ion batteries, while offering high energy density, have compromised safety because they use flammable organic electrolytes.
Aqueous batteries use water as the solvent for electrolytes, significantly enhancing the safety of the batteries. However, due to the limited solubility of the electrolyte and low battery voltage, aqueous batteries typically have a lower energy density. This means that the amount of electricity stored per unit volume of aqueous battery is relatively low.
In a new study published in Nature Energy, a research group led by Prof. Li Xianfeng from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS), in collaboration with Prof. Fu Qiang’s group also from DICP, developed a multi-electron transfer cathode based on bromine and iodine, realizing a specific capacity of more than 840 Ah/L, and achieving an energy density of up to 1,200 Wh/L based on catholyte in full battery testing.
