The new research was published in the Journal Science. “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]. Two-dimensional black phosphorus (2D BP) possesses huge potential in electrochemical energy storage field owing to its unique electronic structure, high charge carrier mobility, and large interlayer spacing. Credit: DONG Yihan, SHI Qianhui and LIANG Yan A new electrode material could make it possible to construct lithium-ion batteries with a high charging rate and storage capacity. Black phosphorus (BP) has received wide attention due to its high theoretical capacity (2596 mAh g −1) and good electron mobility, but its cyclic stability is poor.Meanwhile, it can be complementary to carbon material, which has low theoretical capacity but good cycle stability. Full details of the research are published in Science. A new electrode material could make it possible to construct lithium-ion batteries with a high charging rate and storage capacity. Black phosphorus (black P), which is a promising candidate as an anode material for lithium-ion batteries, was synthesized by a high-pressure and high-temperature (HPHT) method from white and red phosphorus. For context, an anode material that can charge at 13 A/g with a reversible capacity of 440 mA.hour/g implies that an advanced lithium-ion battery made with this technology could be charged in less than 10 minutes. 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 … This deformation, which begins at the edges of the black phosphorus layers, reduces the material’s quality to such an extent that lithium ions cannot easily transfer through it. The black phosphorus composite material connected by carbon-phosphorus covalent bonds has a more stable structure and a higher lithium ion storage capacity. Researchers led by Ji at USTC and Xiangfeng Duan at the University of California, Los Angeles, made their new anode material by combining graphite with black phosphorus. This 2D layered material had been considered before as a candidate for anodes, but tests showed that its electrochemical performance was far below its theoretical potential. A single elemental hybrid composed of black phosphorus (BP) and red phosphorus (RP) is synthesized via a feasible sonochemical method.

The anode in most lithium-ion batteries is made of graphite. Towards higher energy density and fast chargingThe researchers tested the charging-cycle performance of their new electrode material by preparing sample electrodes using a method that is compatible with industrial fabrication processes. Phosphorene is the name given to a monolayer of black phosphorus. Researchers from China, Taiwan and the US report developing a 2D black phosphorus composite anode that supports a high charging rate without sacrificing capacity and cycling stability. 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). “A typical trade-off lies in the storage capacity and rate capability of the electrode material,” co-team leader Hengxing Ji tells Physics World. For context, an anode material that can charge at 13 A/g with a reversible capacity of 440 mA.hour/g implies that an advanced lithium-ion battery made with this technology could be charged in less than 10 minutes. This 2D layered material had been considered before as a candidate for anodes, but tests showed that its electrochemical performance was far below its theoretical potential. Here we synthesized black P by a high pressure and high temperature … Maximizing the performance of all these materials at the same time is a longstanding goal of battery research, yet in practice, improvements in one usually comes at the expense of the others. New black phosphorus anode material. Recommended for you. On its own, black phosphorus isn't a great material for batteries, but a Chinese-US team has figured out how to manipulate it so it works much better. The anode in most lithium-ion batteries is made of graphite. New black phosphorus anode materialThe anode in most lithium-ion batteries is made of graphite. The formation of covalent bonds with graphitic carbon restrains edge reconstruction in layered BP particles to ensure open edges for fast Li+entry; the coating Layer-structured black phosphorus (BP) demonstrating high specific capacity has been viewed as a very promising anode material for future high-energy-density Li-ion batteries (LIBs). However, a series of current studies have found that there is a certain gap between the comprehensive performance indicators of black phosphorus … 570 Westwood Plaza This paper reviews the recent progress on electronic and optoelectronic devices based on 2D black phosphorus (BP). Researchers led by Ji at USTC and Xiangfeng Duan at the University of California, Los Angeles, made their new anode material by combining graphite with black phosphorus. Physics World represents a key part of IOP Publishing's mission to communicate world-class research and innovation to the widest possible audience. By combining black phosphorous with graphite, Ji, Duan and colleagues showed that the chemical bonds between the two materials stabilize the edge structure and prevent unwanted edge changes. This 2D layered material had been considered before as a candidate for anodes, but tests showed that its electrochemical … Layered black phosphorus (BP) exhibits several attractive features for high-rate, high-capacity Li storage. Comparison on the different preparation methods and processes, characteristics, and applications of few-layer BP is presented. However, its practical application is hindered by large volume change of BP and poor mechanical stability of BP anodes by traditional slurry casting technology. A battery’s performance thus depends largely on the materials used in the electrodes and electrolyte, which need to be able to store and transfer many lithium ions in a short period – all while remaining electrochemically stable – so they can be recharged hundreds of times. The term is also often used to describe several stacked monolayers, alternatively known as ‘few-layer phosphorene’ or ‘few-layer black phosphorus’. Publishing fundamental and applied research of the highest quality covering all aspects of graphene and related two-dimensional materials. Lithium ions are the workhorse in many common battery applications, including electric vehicles. If scaled up, the anode material developed by researchers at the University of Science and Technology of China (USTC) and colleagues in the US might be used to manufacture batteries with an energy density of more than 350 watt-hours per kilogram – enough for a typical electric vehicle (EV) to travel 600 miles on a single charge. They found that their test devices had reversible capacities of 910 mA.hour/g, 790 mA.hour/g  and 440 mA.hour/g after more than 2000 cycles at 2.6 A/g, 5.2 A/g and 13 A/g, respectively. Black phosphorus (BP), an allotrope of phosphorus with orthorhombic structure has recently emerged, after having been known for over 100 years, as one of the next generation 2D materials with layered structure. To overcome the continued formation and build-up of an ionically less conductive solid-electrolyte interphase, the team applied a thin polyaniline gel coating to the electrode materials – a strategy that also reinforced the transport path for lithium ions. As a result, the increase in battery capacity usually leads to a long charging time, which represents a critical roadblock for more widespread adoption of EVs.”. Engineered electrode material moves battery development closer to fast charging by University of Science and Technology of China The black phosphorous composite â ¦ Black phosphorus, which is a relatively rare allotrope of phosphorus, was first discovered by Bridgman in 1914. Juyun Kim, Byoungnam Park, Fabricating and Probing Additive-Free Electrophoretic-Deposited Black Phosphorus Nanoflake Anode for Lithium-Ion Battery Applications, Materials Letters, 10.1016/j.matlet.2019.07.089, (2019). First, the crystal structure, band structure, and optical properties of BP, as well as some currently-known passivation methods used for making BP stable in ambient conditions are briefly summarized.

One reason for the shortfall is that the material’s structure deforms during battery operation. Tel: (310) 267-4838 In‐depth understanding of the redox reactions between BP and the alkali metal ions is key to reveal the potential and limitations of BP, and thus to guide the design of BP‐based composites for high‐performance alkali metal ion batteries. A Black Phosphorus-Graphite Composite Anode for Li-/Na-/K-Ion Batteries Black phosphorus (BP) is a desirable anode material for alkali metal ion storage owing to its high electronic/ionic conductivity and theoretical capacity. By way of comparison, the Tesla Model S can travel 400 miles on one charge. A new electrode material could make it possible to construct lithium-ion batteries with a high charging rate and storage capacity. This article was originally published by Physics World. Compared with red and white allotropes of phosphorus‚ black phosphorus is a more thermodynamically stable semiconductor material. One reason for the shortfall is that the material’s structure deforms during battery operation. “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. The black phosphorus composite material connected by carbon-phosphorus covalent bonds has a more stable structure and a higher lithium ion storage capacity. We report use of black phosphorus (BP) as the active anode for high-rate, high-capacity Li storage. Ionic scissors cut out phosphorene nanoribbons.
