  • Non-aqueous electrolyte and lithium secondary battery comprising same
    Patent number: 7968234
    Abstract: An electrolyte for a lithium secondary battery includes lithium salts, a non-aqueous organic solvent, and additive compounds, which initiates decomposition at 4V to 5V and show a constant current maintenance plateau region of more than or equal to 0.5V at measurement of LSV (linear sweep voltammetry). The additive compounds added to the electrolyte of the present invention decompose earlier than the organic solvent to form a conductive polymer layer on the surface of a positive electrode by increased electrochemical energy and heat at overcharge. The conductive polymer layer prevents decomposition of the organic solvent. Accordingly, the electrolyte inhibits gas generation caused by decomposition of the organic solvent during high temperature storage, and also improves safety of the battery during overcharge.

  • Method for managing the power in the wireless network
    Patent number: 7969912
    Abstract: A method is provided for checking whether information on a request for a mode change is received for a prescribed channel time such that a device configuring a network enters a power save mode when not performing data transmission/reception and a modem enters an awake state from a sleep state for the prescribed channel time. The prescribed channel time is determined to correspond to a time for transmitting a beacon. The modem of a device in a power save mode enters an awake state for a channel time period for broadcasting a beacon and then checks whether information on a power management mode change is received. If the information is not received, a sleep state is reentered. If the power management mode change information is received, power is managed by performing data transmission/reception by switching to a normal mode.
