Yin and yang: Opposites in nature, fluoride and lithium, compete for higher-energy batteries

The chemical element that makes up most of today’s batteries, lithium, may soon be challenged by its polar opposite on the periodic table: fluoride. Yes, the same stuff in toothpaste. The two elements would be in competition for helping electronics last longer on a charge, such as electric cars that need to travel more miles than is possible with lithium-ion batteries on the market. Researchers are one step closer to equipping fluoride-based batteries for battle with improvements that allow the technology to operate at room temperature. Up until this point, fluoride had been limited to building high-temperature batteries that are impractical for our electronic devices.

Purdue study: Sustainable palm oil doesn’t make the grade

From food and biofuels to cosmetics and detergents, palm oil is found in countless products these days. Demand for the oil has surged in the last decade. But what sounds good for us isn’t good for the forests where oil palms (Elaeis guineensis) are harvested. According to a Purdue University study, deforestation is rising in major oil palm-producing countries. And it’s happening even faster in areas certified as “sustainable.”
