  • NEGATIVE ELECTRODE ACTIVE MATERIAL FOR LITHIUM SECONDARY BATTERY, METHOD FOR PREPARING SAME, AND LITHIUM SECONDARY BATTERY COMPRISING SAME
    Publication number: 20260135085
    Abstract: The present invention relates to a negative electrode active material for a lithium secondary battery, a method for preparing same, and a lithium secondary battery comprising same. More specifically, the negative electrode active material comprises one selected from Li1.1Ti0.9O2 and a mixture in which Li1.1Ti0.9O2 and carbon nanotubes (CNTs) are mixed in a weight ratio of 8:2 to 9:1. The negative electrode active material for a lithium secondary battery, comprising the above-described components has an R-3m structure, and provided is a lithium secondary battery which exhibits high capacity and excellent lifespan characteristics, and in particular, exhibits high capacity during high-rate charging and discharging.

  • Grid for transmission electron microscopy tomography and method of fabricating the same
    Patent number: 7820982
    Abstract: Disclosed is a moon grid for transmission electron microscopy tomography, including a mesh sheet for protecting an upper objects and a support film formed on the mesh sheet and having nanoparticles dispersed throughout, in which the nanoparticles dispersed throughout the support film are used as reference points in the reconstruction of two-dimensional transmission electron microscopy images into a three-dimensional image, thus omitting a process of attaching markers in the course of preparation of a sample and easily forming reference points even on a sample to which it is impossible to attach markers. A method of fabricating such a moon grid is also provided.
