Black phosphorus (BP) is a desirable anode material for alkali metal ion storage owing to its high electronic/ionic conductivity and theoretical capacity. This paper reviews the recent progress on electronic and optoelectronic devices based on 2D black phosphorus (BP). The website forms part of the Physics World portfolio, a collection of online, digital and print information services for the global scientific community. 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). “A typical trade-off lies in the storage capacity and rate capability of the electrode material,” co-team leader Hengxing Ji tells Physics World. However, a series of current studies have found that there is a certain gap between the comprehensive performance indicators of black phosphorus … Constructing stable covalent bonding in black phosphorus/reduced graphene oxide for lithium ion battery anodes† Yang Shi , ‡ a Zhibin Yi , ‡ a Yanping Kuang , a Hanyu Guo , a Yingzhi Li , a Chen Liu * b and Zhouguang Lu * a The term is also often used to describe several stacked monolayers, alternatively known as ‘few-layer phosphorene’ or ‘few-layer black phosphorus’. 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 new research was published in the Journal Science. 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 … Recommended for you. Layered black phosphorus (BP) exhibits several attractive features for high-rate, high-capacity Li storage. New black phosphorus anode material The anode in most lithium-ion batteries is made of graphite. It was first synthesized by heating white phosphorus under high pressures (12,000 atmospheres) in 1914. 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. 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.

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. One reason for the shortfall is that the material’s structure deforms during battery operation. Lithium ions are the workhorse in many common battery applications, including electric vehicles. Los Angeles, CA 90095 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. BP and RP can construct a new single elemental heterostructure. Compared with red and white allotropes of phosphorus‚ black phosphorus is a more thermodynamically stable semiconductor material. This 2D layered material had been considered before as a candidate for anodes, but tests showed that its electrochemical … 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.”. The 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. The black phosphorous composite material connected by carbon-phosphorus covalent bonds has a more stable structure and a higher lithium ion … 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. 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. 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. New black phosphorus anode materialThe anode in most lithium-ion batteries is made of graphite. Black phosphorus is an allotrope of white phosphorus, and it is an electrode material with great potential to meet the requirements of fast charging. 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. 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. By way of comparison, the Tesla Model S can travel 400 miles on one charge. 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. 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 study revealed the electrochemical activity of pure black P under different pressures and temperatures systematically. 24a). 570 Westwood Plaza 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. 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. Formation of Stable Phosphorus−Carbon Bond for Enhanced Performance in Black Phosphorus Nanoparticle−Graphite Composite Battery Anodes Jie Sun,†,# Guangyuan Zheng,‡ Hyun-Wook Lee,† Nian Liu,§ Haotian Wang,∥ Hongbin Yao,† Wensheng Yang,*,# and Yi Cui*,†,⊥ †Department of Materials Science and Engineering, ‡Department of Chemical Engineering, §Department of Chemistry, and 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. A single elemental hybrid composed of black phosphorus (BP) and red phosphorus (RP) is synthesized via a feasible sonochemical method. During operation, these ions move back and forth between the anode and cathode through an electrolyte as part of the battery’s charge-discharge cycle. Black phosphorus obtained from white phosphorus at 4 GPa and 400 °C exhibited the highest first discharge and charge capacities of 2,505 and 1,354 mAh g-1.Black phosphorus obtained from red phosphorus at 4.5 GPa and 800 °C exhibited the highest first discharge and charge capacities of 2,649 and 1,425 mAh g-1.. 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. “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.
