Powered by lithium-sulfur batteryEveryday life is powered by batteries. This includes
smart watches, cell phones, and electric cars. These devices use lithium-ion batteries
technology. While lithium-ion batteries are a great
technology, there are still some drawbacks. They can overheat, have short
lifespans and have difficulty sourcing certain raw materials.The US Department of Energy's Argonne National Laborator
is researching ways to solve these problems by testing new materials for
battery construction. Sulfur is one such material. It is
abundant, cost-effective, and can store more energy than traditional ion
batteries.Researchers have created a layer in the battery to
increase energy storage capacity and nearly eliminate corrosion, a new study
shows.A promising battery design combines a positive electrode
with sulfur (cathode), and a negative electrode with lithium metal (anode). The electrolyte is the substance that allows for
ions...
