The critical minerals that power lithium-ion batteries are in high demand and short supply, especially for the U.S., which must rely on importing resources such as nickel and cobalt to manufacture the technology.

Cornell researchers have now developed a more efficient and cost-effective way to recover almost the full life of these batteries after they are spent. By using an electrochemical solution to regenerate their electrodes, the recycled batteries can regain up to 95% of their original power and last longer when reused, the researchers demonstrated.

The process could also slash current recycling costs by 56% and would be more environmentally friendly than current methods.

The findings were published in Energy & Environmental Science...

Eating foods that contain common preservative food additives may increase the risks of high blood pressure and cardiovascular disease, according to research published in the European Heart Journal.

The research was led by Dr. Mathilde Touvier, a research director at INSERM (the French National Institute for Health and Medical Research), and Anaïs Hasenböhler, Ph.D. student, both from the Nutritional Epidemiology Research Team at the Université Sorbonne Paris Nord and Université Paris Cité, France.

Ms. Hasenböhler said, “Food preservatives are used in hundreds of thousands of industrially processed foods...

Many plastic products are designed to be used only once, yet the material itself lasts for years. But a new strategy is addressing this problem by creating products that self-destruct on command, known as living plastics. These materials incorporate activatable, plastic-degrading microbes alongside the polymers. One team reporting in ACS Applied Polymer Materials used two bacterial strains that worked together and completely broke down the material within just six days, without making microplastics.

Renewable energy technologies, such as solar cells and wind turbines, are becoming increasingly widespread in many countries worldwide. Reliably storing the electricity produced by these devices, so that it can be used later at times when sunlight or wind are scarce, would further improve their effectiveness as sustainable energy solutions.

A promising solution to store solar and wind energy entails the use of aqueous zinc (Zn) metal batteries. These are low-cost, safe and environmentally friendly batteries that store and release energy, leveraging water-based solutions and Zn anodes.

Despite their potential, Zn batteries have not yet achieved the de...
