摘要: As an electrode for a power storage device, an electrode including a current collector, a first active material layer over the current collector, and a second active material layer that is over the first active material layer and includes a particle containing niobium oxide and a granular active material is used, whereby the charge-discharge cycle characteristics and rate characteristics of the power storage device can be improved. Moreover, contact between the granular active material and the particle containing niobium oxide makes the granular active material physically fixed; accordingly, deterioration due to expansion and contraction of the active material which occur along with charge and discharge of the power storage device, such as powdering of the active material or its separation from the current collector, can be suppressed.

摘要: The roll paper loading mechanism of a roll paper printer has a left side panel rendered in unison with a roll paper holder. The roll paper holder pivots to the front of the printer in conjunction with the operation opening an access cover. When the access cover is opened completely, the left side panel protrudes through an opening formed in the printer case to the front of the printer. A right side panel disposed to hold the roll paper between it and the left side panel is stationary inside the printer case. A roll paper guide tab that projects to the front of the printer and extends away from the left side panel is formed on the front end of the right side panel.

摘要: To provide a carbon-based negative electrode material which can be used with an electrolyte containing PC as a main ingredient, a carbon-based negative electrode material having a graphene layer structure is crystalline and has pores. That is, the crystal structure of the carbon-based negative electrode material is distorted more significantly than that of graphite. Accordingly, the carbon-based negative electrode material has a larger interlayer distance between graphenes than graphite. It has been shown that such a negative electrode material can be used for a secondary battery which contains an electrolyte containing PC as a main ingredient.
