Abstract:
A polymer electrolyte for a lithium battery, wherein the polymer electrolyte includes a polymerization product of a lithium ion conductive compound including an ethylenically unsaturated bond, a lithium ion conductive unit, and an ion-exchangeable functional group; and a heteroatom-containing ionic liquid polymerizable with the lithium ion conductive compound.
Abstract:
An electronic device and a method of securing the electronic device are provided. The method includes displaying content and recognizing at least one of a tilt, a sound, or a voice. Then, comparing preset reference data to at least one of an angle corresponding to the tilt, data corresponding to the sound, or data corresponding to the voice. Further, activating a secure mode for the displayed content, when the at least one of the angle corresponding to the tilt, the data corresponding to the sound, or the data corresponding to the voice is consistent with the preset reference data. Another embodiment includes displaying content, recognizing a connection with an external electronic device, and activating a secure mode for the displayed content, in response to the recognized connection. Additional features may include requesting the connected external electronic device to display the content, and then altering and displaying the altered content thereon.
