Electric storage device

摘要

An electric storage device (10) has a first electric storage component (29) and a second electric storage component (30). The first component (29) and the second component (30) are connected in parallel. A positive-electrode mixture layer (22) contains lithium cobaltate to increase a capacity. A positive-electrode mixture layer (27) contains activated carbon to increase an output. A current collector (16) having through holes (16a) is provided between the layers (22) and (27). A positive electrode terminal (25) is connected to a positive-electrode current collector (21) of the first component (29) through an electricity supply path (24) provided with a resistor (23). By this configuration, the electric current flowing through the first electric storage component (29) can be restricted when the device is charged or discharged with high current.
