  • Method of making thin films of sodium fluorides and their derivatives by ALD
    Patent number: 12065738
    Abstract: A method of making thin films of sodium fluorides and their derivatives by atomic layer deposition (“ALD”). A sodium precursor is exposed to a substrate in an ALD reactor. The sodium precursor is purged, leaving the substrate with a sodium intermediate bound thereon. A fluorine precursor is exposed to the bound sodium intermediate in the ALD reactor. The fluorine precursor is purged and a sodium fluoride film is formed on the substrate.

  • Lithium secondary battery
    Patent number: 11063290
    Abstract: A lithium secondary battery prepared to a negative electrode free battery, and forming lithium metal on a negative electrode current collector through charge. The lithium secondary battery forms lithium metal while being blocked from the atmosphere, and since production of a surface oxide layer (native layer) formed on an existing negative electrode is fundamentally blocked, resulting battery efficiency and lifetime property decline may be prevented.
