The positive electrode material for lithium ion batteries comprises a composite positive electrode material consists of LiCoO | 01-19-2012 |
| 20100233530 | BATTERY AND BATTERY ENVELOPING ASSEMBLY CONVENIENT FOR ASSEMBLY - A battery enveloping assembly and a battery incorporating such an enveloping assembly are disclosed. The enveloping assembly comprises an explosion-proof assembly and an enveloping plate. A casing extends downwardly from the enveloping plate. An external surface of the enveloping plate is provided with a connection portion protruding outwardly relative to the casing. A cavity configured to house the explosion-proof assembly is formed in the casing. A lower portion of the casing is bent inwardly to form a bending portion so as to secure the explosion-proof assembly inside the casing in an insulating and sealing manner. A first through hole through which an electrode is connected to the explosion-proof assembly is provided at a center of the bending portion, and a second through hole through which an electrode extends out from the explosion-proof assembly is provided in the enveloping plate which is disposed on the top of the casing. | 09-16-2010 |
| 20100029090 | NOVEL CONTACT ETCH STOP FILM - A system and method for improved dry etching system. According to an embodiment, the present invention provides a partially completed integrated circuit device. The partially completed integrated circuit device includes a semiconductor substrate having a surface region. The partially completed integrated circuit device also includes an etch stop layer overlying the surface region.
