LiNi 0.5 Mn 1.5 O 4 (LNMO) is a derivative of the commercialized spinel LiMn 2 O 4 with Ni 2+ and Mn 4+ occupying two octahedral sites of 4a and 16d, respectively aimed at suppressing the intrinsic defi ciencies such as the Jahn–Teller distortion of Mn 3+with the same theoretical capacity as LiMn 2 O 4 (148 mAh g –1 ). [ 1 ] In addition, since the working mechanism of LiNi 0.5 Mn 1.5 O 4 i…
Abstract. A simple, highly effective method for the functionalization of CNTs with HNO3 vapor is developed, thus eliminating separation by filtration. A significantly higher amount of oxygen species compared to conventional wet HNO3 treatment was detected by X-ray photoelectron spectroscopy, and the morphology and the degree of agglomeration did not deteriorate because of the treatment.
Abstract. The monoalkyl chain derivatives of succinic acid self-assemble into ordered bilayer aggregates by forming dimers of hydrogen bonded carboxylic acid in a number of organic solvents and finally gelatinize the solvents. The gelation ability of each derivative was inspected. The morphologies of xerogels were investigated by scanning electron microscope (SEM). The microstructure of agg…
