  • Patent number: 10205164
    Abstract: Provided are a porous silicon-based anode active material including porous SiOx particles (0?x<2) having surfaces coated with an oxide layer, a method of preparing the same, and a lithium secondary battery including the porous silicon-based anode active material. Since the anode active material includes an oxide layer formed on the porous SiOx particles (0?x<2), a reactivity between the anode active material and an electrolyte solution may be reduced and, as a result, an electrical short circuit in an electrode may be minimized. Also, since a plurality of pores is included in surfaces or the surfaces and inside of the SiOx particles, a thickness change rate of the electrode generated during charge and discharge of a secondary battery may be reduced and lifetime characteristics may be improved.

  • Patent number: 9947922
    Abstract: Provided are a porous silicon-based particle including a silicon (Si) or SiOx(0<x<2) particle, wherein the particle includes a plurality of nonlinear pores, and the nonlinear pores are formed as open pores in a surface of the particle, and a method of preparing the porous silicon-based particles. Porous silicon-based particles according to an embodiment of the present invention may be more easily dispersed in an anode active material slurry, may minimize side reactions with an electrolyte, and may reduce volume expansion during charge and discharge. Also, according to an embodiment of the present invention, the shape, form, and size of pores formed in the porous silicon-based particle may be controlled by adjusting the type of a metal catalyst, the concentration of the catalyst, and etching time.

  • Patent number: 8484584
    Abstract: At least one pattern of a photomask is identified that has a likelihood of causing collapse of a microelectronic device feature that is formed using the photomask, due to surface tension of a solution that is applied to the feature during manufacture of the microelectronic device. The patterns of the photomask are then modified to reduce the likelihood of the collapse. The photomask may be formed and the photomask may be used to manufacture microelectronic devices. Related methods, systems, devices and computer program products are described.
