Patent number: 11367865Abstract: Disclosed is a method of manufacturing a composite anode material for a lithium secondary battery containing nano-sized silicon and a carbonaceous material through a single process, the method including mixing a carbonaceous material and solid silicon and performing carbothermal shock for rapidly heating the carbonaceous material so that the solid silicon is melted using the heated carbonaceous material and is dispersed and attached in the form of particles to the surface of the carbonaceous material, the size of the silicon particles, which grow on the surface of the carbonaceous material, being adjusted during the carbothermal shock. Accordingly, processing costs can be lower than conventional methods of manufacturing silicon nanoparticles, and manufacturing costs can be further reduced by simultaneously performing formation of the silicon nanoparticles and compounding with the carbonaceous material.Type: GrantFiled: November 18, 2019Date of Patent: June 21, 2022Assignee: HPK INC.Inventors: Chang Hyun Cho, Chang Se Woo, Kap Seung Yang, Chang Ha Lim, Chung Hyung Joh

Patent number: 8696469Abstract: In embodiments of the present invention improved capabilities are described for a computer program product embodied in a computer readable medium that, when executing on one or more computers, receives a request for game play, and in response to the request, causing prior game play data to be retrieved, where the prior game play data was stored in response to prior game play of another user. Further, an asynchronous game play environment may be provided where an active participant, who made the request, is able to play against and interact with an apparently live participant based on the prior game play data.Type: GrantFiled: January 18, 2013Date of Patent: April 15, 2014Assignee: Tetris Online, Inc.Inventors: Eui-Joon Youm, Glyn C. Thomas, Chang-ha Lim
