Coupling Water‐Proof Li Anodes with LiOH‐Based Cathodes Enables Highly Rechargeable Lithium–Air Batteries Operating in Ambient Air

Mace-like Fe3O4 nanostructures with a length of 200–300 nm and a diameter of 10–30 nm were successfully synthesized via a microemulsion-mediated solvothermal method and used as an electrode catalyst for lithium–air batteries. The results showed that the mace-like Fe3O4 nanostructures were obtained by adjusting the NaOH concentration and reaction temperature, and by adding polyethylene glycol-1000. The growth and assembly mechanism of the mace-like Fe3O4 nanostructures was also discussed. Polyethylene glycol-1000 not only acted as a soft template to form Fe3O4 nanorods, but also assisted in the assembly of the Triton X-100-decorated Fe3O4 nanoparticles onto the nanorods. The results of charge–discharge tests showed that the lithium–air battery based on mace-like Fe3O4 nanostructures exhibited a high discharge capacity of 1427 mA h g−1 in ambient air. The unique one-dimensional mace-like Fe3O4 nanostructures could effectively enhance the catalytic activity for the oxygen evolution reduction process, which is effective for decreasing the charging potential plateau.

Lithium Air Batteries

A cathode composed of RuO2 nanoparticle-decorated NiO nanosheets not only catalyzes the oxygen reduction and evolution reactions, but also promotes the decomposition of the side products (LiOH and Li2CO3), enabling a non-aqueous lithium–air battery to be truly operated in ambient air.

Identification And Quantification

A methodology has been developed and demonstrated which is capable of determining total amounts of asbestos fibers and fibrils in air ranging from as low as fractional nanograms per cubic meter (ng/m3) of air to several micrograms/m3. The method involves the collection of samples on an absolute filter and provides an unequivocal identification and quantification of the total asbestos contents including fibrils in the collected samples.The developed method depends on the trituration under controlled conditions to reduce the fibers to fibrils, separation of the asbestos fibrils from other collected air particulates (beneficiation), and the use of transmission microscopy for identification and quantification. Its validity has been tested by comparative analyses by neutron activation techniques. It can supply the data needed to set emissions criteria and to serve as a basis for assessing the potential hazard for asbestos pollution to the populace.

Ambient Air Quality Standards

The Clean Air Act Amendments of 1970 provide the basis for a dramatic change in Federal air quality programs. The Act establishes new standards for motor vehicles and requires EPA to establish national ambient air quality standards, standards of performance for new stationary sources of pollution, and standards for stationary sources emitting hazardous substances. Further, it establishes procedures which allow states to set emission standards for existing sources in order to achieve national ambient air quality standards. The Act also permits the Administrator of EPA to register fuels and fuel additives and to regulate the use of motor vehicle fuels or fuel additives which pose a hazard to public health or welfare.National air quality standards for particulate matter have been established. Asbestos, mercury, and beryllium have been designated as hazardous air pollutants for which Federal emission standards have been proposed.

At the present time the primary objective of the electron microscopy group of the Air and Industrial Hygiene Laboratory is the development of a method suitable for use in establishing an air quality standard for asbestos in ambient air and for use in its surveillance. The main concept and thrust of our approach for the development of this method is to obtain a true picture of fiber occurrence as a function of particle size and asbestos type utilizing light and electron microscopy.We have now available an electron micrographic atlas of all asbestos types including selected area diffraction patterns and examples of fibers isolated from air samples. Several alternative approaches for measuring asbestos in ambient air have been developed and/or evaluated. Our experiences in this regard will be described. The most promising method involves: 1) taking air samples on cellulose ester membrane filters with a nominal pore size of 0.8 micron; 2) ashing in a low temperature oxygen plasma for several hours;
