Massachusetts Institute of Technology engineers have designed a battery made from inexpensive, abundant materials, that could provide low-cost backup storage for renewable energy sources. Less expensive than lithium-ion battery technology, the new architecture uses aluminum and sulfur as its two electrode materials with a molten salt electrolyte in between. The new battery architecture is described […]

A Rensselaer Polytechnic Institute team proposed a greener, more efficient, and less expensive energy storage alternative to lithium ion. The driving force is concerns regarding scarcity, high prices, and safety regarding the long-term use of lithium-ion batteries. In research published recently in Proceedings of the National Academy of Sciences (PNAS), corresponding author Nikhil Koratkar, the […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… The Rice University lab of chemist James Tour introduced a technique to tune the surface of anodes for batteries by simply brushing powders into them. The powder adheres to the anode and becomes a thin, lithiated coating that effectively prevents the formation of damaging dendrites. A powder of phosphorus and sulfur ground into the […]

Magnesium is a promising material for such solid-state batteries owing to its abundance, but its practical application is limited by the poor conductivity of magnesium ions (Mg2+) in solids at room temperature. The […]

Open Image…Save ImageOpen Image (using #TmpD/ia)… Pacific Northwest National Laboratory researchers have designed a sodium ion battery that is much more durable and reliable in lab tests. After 300 charging cycles, it retained 90 percent of its charging capacity. Cheap and abundant, sodium is a prime promising candidate for a new battery chemistry technology. But limited performance of sodium-ion batteries […]
