  • Patent number: 12068478
    Abstract: The present invention provided a positive electrode active material for a lithium secondary battery including lithium cobalt oxide particles. The lithium cobalt oxide particles include lithium deficient lithium cobalt oxide having Li/Co molar ratio of less than 1, belongs to an Fd-3m space group, and having a cubic crystal structure, in surface of the particle and in a region corresponding to a distance from 0% to less than 100% from the surface of the particle relative to a distance (r) from the surface to the center of the particle. In the positive electrode active material for a lithium secondary battery according to the present invention, the intercalation and deintercalation of lithium at the surface of a particle may be easy, and the output property and rate characteristic may be improved when applied to a battery. Accordingly, good life property and the minimization of gas generation amount may be attained even with large sized positive electrode active material.

  • Patent number: 7324530
    Abstract: Provided is a routing method for determining a destination in a computer network having multiple interconnected nodes, the method for measuring packet delays among remotely located gateways and processing routing in application layers of the gateways using the packet delays. The routing method based on packet delay includes the steps of setting a re-routing interval and measuring one-way delays among gateways, exchanging the measured delays among the respective gateways and forming delay time tables, calculating an average one-way delay during the re-routing interval, and if a packet is received, applying the calculated average one-way delay to a predetermined algorithm and determining a path from a source gateway to a destination gateway, the path having the minimum delay. Therefore, an improved routing performance can be achieved in real time transmitting a packet by determining the minimum delay path to a destination by measuring packet delays among remotely located nodes in application layers thereof.
