  • Publication number: 20240145693
    Abstract: The present invention relates to a positive electrode active material and a lithium secondary battery including the same, and more particularly, to a positive electrode active material including an overlithiated lithium manganese-based oxide, which is able to prevent the degradation of the electrochemical properties of a lithium secondary battery, including rate characteristics, caused by an excess of lithium and manganese in the lithium manganese-based oxide by inducing the growth of primary particles constituting the lithium manganese-based oxide, and prevent the lifetime deterioration of a lithium secondary battery by reducing side reactions between the lithium manganese-based oxide and a liquid electrolyte particularly during high-voltage operation, and at the same time, inhibiting or mitigating the release of a transition metal from the lithium manganese-based oxide, and a lithium secondary battery including the same.

  • Patent number: 8495617
    Abstract: Disclosed are an interworking system between a user terminal and a smart card for executing a widget and a method thereof. The interworking system is configured to enable the user terminal to manage the download setup information for a widget UI (user interface) program installed in the smart card. The user terminal is able to download widget UI data to be updated from a program provision server based on the download setup information even if there is no additional request from the smart card. Therefore, the system is able to prevent periodic communication between the user terminal and the smart card when updating the widget UI program.
