Title:
HYBRID CELL
Document Type and Number:
WIPO Patent Application WO2003026054
Kind Code:
A9
Abstract:
A cell capable of being charged/discharged at high rate wherein a molded piece of a positive electrode active material is placed in an electrolytic solution in one of two cells interconnected through a separator, a molded piece of a negative electrode active material is placed in an electrolytic solution in the other cell, and current collectors are disposed in the cells. Conventionally, active materials having the same charging/discharging characters have been used. Therefore, high-rate chargeable/dischargeable cells having a small cell capacity but capable of being charged/discharged with large current and low-rate chargeable/dischargeable cells capable of being charged/discharged with small current and having a large cell capacity have been separately produced, and therefore there have been problems such as the one that there have been no cells capable of being charged/discharged with large current and having a large cell capacity. According to the invention, a combination of at least two kinds of active material molded pieces having different charging/discharging characteristics is used for at least either the positive or negative active material and placed in one cell, thereby solving the above problem.
