摘要:
Disclosed herein is an electrolyte for lithium secondary batteries comprising: a chelating agent, which forms complexes with transition metal ions in the battery, and at the same time does not react and coordinate with lithium ions; a non-aqueous solvent; and an electrolyte salt, as well as a lithium secondary battery comprising the electrolyte. The chelating agent, which is contained in the electrolyte for lithium secondary batteries, can suppress a side reaction in which transition metal ions are reduced and deposited as transition metals on the anode. Also, the chelating agent can suppress internal short-circuits in the battery and the resulting voltage drop of the battery and a reduction in the safety and performance of the battery, which can occur when transition metals are deposited on the anode.

摘要:
A graphic interface device and method in a digital TV. The graphic interface device includes: a transmitting side for coding various forms of user graphic environment which can be selected by an end user, assigning specific packet identification (PID), and multiplexing the assigned PID with video information, audio information and additional information; and a receiving side for parsing and decoding the various forms of graphic environment data of the specific PID transmitted from the transmitting side to be displayed on a screen, thereby being selected by the end user and for parsing and decoding once again the corresponding graphic environment selected by the end user to be displayed on the screen. Thus, the end user can select the graphic environment satisfying his own preference, for example, a dynamic program guide pattern or menu icon.
