A negative electrode for a rechargeable battery including: a current collector, a first layer containing a conductive material to occlude and release lithium ion, the first layer formed on the current collector, a second layer containing a metal selected from lithium and lithium alloy, the second layer formed on the first layer, and a third layer containing a lithium ion conductive material, the third layer formed on the second layer. The third layer prevents the lithium and/or the lithium alloy in the second layer from being in contact with the electrolyte and smoothly feeds the lithium to the second layer to improve the efficiency of the negative electrode. The first layer can occlude and release the part of the lithium to be occluded and released, thereby reducing the volume change of the second layer. Such a structure of the negative electrode enables us to enhance cycling efficiency, and to attain long cycle life and good safety.
摘要:
This invention provides a technique for preventing film quality of a capacitive insulating film made of a ferroelectric film of a FeRAM memory cell from being degraded and for improving the characteristics of the FeRAM memory cell. A shielding film having a higher lead content than that of a capacitive insulating film is formed under a lower electrode of a capacitor in a FeRAM memory cell, and another shielding film having a higher lead content than that of the capacitive insulating film is formed on an upper electrode. PZT films to be used as barrier layers are formed in the interlayer insulating films the FeRAM memory cell. As a result, it is possible to prevent H2 or H2O from entering an upper portion or a lower portion of the capacitor, and lead diffused from the capacitive insulating film 11a can be compensated by lead included in the shielding films, and it is possible to prevent characteristics of the capacitive insulating film 11a from being degraded.
