摘要:
The sintered magnesium oxide according to one embodiment has a density of less than 3.5 g/cm3 and an average grain size of about 3 to about 10 μm. A MgO protective layer made from the sintered magnesium oxide reduces a discharge voltage of a plasma display panel, improves its response speed, and provides it with high-purity film quality.

摘要:
A negative active material, an electrode including the same, and a lithium battery including the electrode. The negative active material has no volumetric expansion and has high solubility with respect to lithium. In addition, the negative active material is in the form of spherical particles, and thus does not require a separate granulating process. Moreover, the negative active material may enhance the capacity of a lithium battery.

A secondary particle and a lithium battery including the same are provided wherein the secondary particle includes a plurality of primary particles and each primary particle contains n polycyclic nano-sheets disposed upon one another. The polycyclic nano-sheets include hexagonal rings of six carbon atoms linked to each other, wherein a first carbon and a second carbon have a distance therebetween of L1. L2 is a distance between a third carbon and a fourth carbon, and the arrangement of the polycyclic nano-sheets is such that L1≧L2. The secondary particle is used as a negative active material in the lithium battery, and the secondary particle contains pores, thereby allowing for effective intercalating and deintercalating of the lithium ions into the secondary particle to impart improved capacity and cycle lifespan.
