A solid polymer electrolyte, a lithium battery employing the same, and methods of forming the electrolyte and the lithium battery. The polymer electrolyte includes polyester (meth)acrylate having a polyester polyol moiety having three or more hydroxide (&#x2014;OH) groups, at least one hydroxde group being substituted by a (meth)acrylic ester group and at least one hydroxide group being substituted by a radical non-reactive group, or its polymer, a peroxide having 6 to 40 carbon atoms, and an electrolytic solution including a lithium salt and an organic solvent.

Polymer electrolyte and lithium battery employing the same

An electrolyte for a lithium secondary battery is provided. The electrolyte includes a lithium salt, a non-aqueous organic solvent, and a compound represented by Formula (1):wherein R, R, and Rare each independently selected from the group consisting of hydrogen, primary, secondary, and tertiary alkyl groups, alkenyl groups, and aryl groups. The compound of the present invention is decomposed earlier than an electrolytic organic solvent, and an organic SEI film is formed on a negative electrode, thereby inhibiting the electrolytic organic solvent from decomposing.

Non-aqueous electrolyte for lithium secondary battery and lithium secondary battery comprising same

The present invention relates to a liquid crystal display. The relation of &#x2208; (permittivity). sg(r) (resistivity) between a liquid crystal layer, an aligning layer or an overcoat for preventing poor images is established. An LCD according to the present invention includes a first panel including a plurality of devices thereon and an aligning layer formed on the entire surface thereof, a second panel opposite to the first panel and including an overcoat and an aligning layer sequentially formed on the entire surface thereof, and a liquid crystal layer interposed between the first pane) and the second panel. It is preferable that the aligning layer, the liquid crystal layer and the overcoat satisfy the relation (a). An LCD according to another embodiment includes a first panel including a plurality of devices thereon and an aligning layer formed on the entire surface thereof, a second panel opposite to the first panel and including an overcoat and an aligning layer sequentially formed on the entire surface thereof, and a liquid crystal layer interposed between the first panel and the second panel. It is preferable that the liquid crystal and the overcoat satisfy the relation (b).
