摘要:
A lithium secondary battery having a cap assembly including a cap plate, an insulation plate and a terminal plate. The insulation plate and the terminal plate each have a predetermined vent hole corresponding to a safety vent formed on the cap plate so that if the secondary battery is dropped, an electrolyte passes through the vent-holes and undergoes a pressure reduction, thereby preventing fracture of a safety vent by the electrolyte while allowing gas to be exhausted upon battery overcharge, full discharge or by overheating.

A method for fabricating an oxide thin film transistor includes sequentially forming a gate insulating film, an oxide semiconductor layer, and a first insulating layer; selectively patterning the oxide semiconductor layer and the first insulating layer to form an active layer and an insulating layer pattern on the gate electrode; forming a second insulating layer on the substrate having the active layer and the insulating layer pattern formed thereon; and selectively patterning the insulating layer pattern and the second insulating layer to form first and second etch stoppers on the active layer. The oxide semiconductor layer may be a ternary system or quaternary system oxide semiconductor comprising a combination of AxByCzO (A, B, C═Zn, Cd, Ga, In, Sn, Hf, Zr; x, y, z≧0).

The present disclosure relates to a thin film transistor substrate for flat panel display device including oxide semiconductor. The present disclosure suggests a thin film transistor substrate for flat panel display device comprising: a transparent substrate; a thin film transistor layer having an oxide semiconductor material disposed on the transparent substrate; a passivation layer disposed on the whole surface of the thin film transistor layer; a pixel electrode formed on the passivation layer and contact the thin film transistor layer through a contact hole formed at the passivation layer; and a first ultra violet light absorbing layer disposed on the whole surface of the pixel electrode. Absorbing all of ultra violet light and passing all of the visible light, the photo-thermal characteristic is enhanced and the transparency property is not degraded.

摘要:
An electrode assembly is adapted to prevent the separator from contracting due to heat that is generated near the electrode tab during overcharging, over-discharging, or in the case of an internal short circuit. The electrode assembly also prevents an additional short circuit between the electrode plates. A rechargeable battery that comprises the electrode assembly is also provided. The present invention prevents the electrode tab from being short-circuited due to increased heat generation during overcharging or in the case of a short circuit, thus improving the safety of the rechargeable battery.
