This article was originally published by Physics World. Black phosphorus, which is a relatively rare allotrope of phosphorus, was first discovered by Bridgman in 1914. “For example, anode materials with high lithium storage capacity, such as silicon, are usually reported as having low lithium-ion conductivity, which hinders fast battery [charging]. However, a series of current studies have found that there is a certain gap between the comprehensive performance indicators of black phosphorus … Since the advent of two-dimensional (2D) black phosphorus (which is known as phosphorene due to its resembling graphene sheets) in early 2014, research interest in the arena of black phosphorus was reignited in the scientific and technological communities. Black phosphorus is an allotrope of white phosphorus, and it is an electrode material with great potential to meet the requirements of fast charging. An electrode made of the new black phosphorus composite can recover about 80 percent of its power after a nine-minute charge, and 90 percent charge capacity can be maintained after charging 2,000 times, said Xin Sen, one of the paper's authors and researcher at … Black phosphorus is the thermodynamically stable form of phosphorus at room temperature and pressure, with a heat of formation of -39.3 kJ/mol (relative to white phosphorus which is defined as the standard state). Ball milling method is simple and productive, and can control the ratio of … However, its practical application is hindered by large volume change of BP and poor mechanical stability of BP anodes by traditional slurry casting technology. “If scalable production can be achieved, this material may provide an alternative, updated graphite anode, and move us toward a lithium-ion battery with an energy density of higher than 350 watts-hour per kilogram,” says Sen Xin, a researcher at the Institute of Chemistry, Chinese Academy of Sciences, and one of the study’s co-first authors.This figure, he adds, means that an electric vehicle equipped with such a battery could travel 600 miles on a single charge – making it competitive with conventional combustion-engine vehicles.
