Abstract

PURPOSE:To maintain stable voltage free from a substantial discharge voltage drop by integrating the polarizable electrode of an electrical double layer capacitor with positive and negative electrodes of a battery. CONSTITUTION:A negative power collector 1 and a positive power collector 5 are made of a stainless steel foil. A polarizable electrode 2 comprises an electrical double layer capacitor made of active carbon or carbon fiber, and a negative active material layer 3 comprises graphited carbon. Furthermore, a electrolytical layer 4 comprises a polypropylene fine porous film and an organic electrolyte. A positive active material layer 6 comprises vanadium oxide. In the case of a load requiring a substantial amount of current in an initial discharge stage, the electrical double layer capacitor absorbs the load of the substantial current, and prevents discharge voltage from a substantial drop. Also, the battery electrode absorbs discharge in stationary current. According to the aforesaid construction, a single battery provides the characteristics of both the electrical double layer capacitor and the battery itself, thereby enabling stable voltage to be maintained for a long time.

Conventional technology and its problems Conventional electric double layer capacitors are capable of instantaneous large current discharge because they utilize the charge accumulated in the electric double layer due to the physical adsorption of ions from the electrolyte onto the surface of the activated carbon electrode. However, the electrical capacity is extremely small.

The thickness of the electrolyte layer was 25 μm, and the electrolytic solution used was a mixture of propylene carbonate and dimethoxyethane in which lithium perchlorate was dissolved.

For comparison, FIG. 3 shows a comparative diagram of discharge characteristics when a conventional battery (No. 2) without polarizable electrodes was discharged under the same load conditions as the battery of the present invention. Note that the conventional batteries had the same electrode area, the thickness of the positive electrode, the negative electrode active material layer, etc., except that they did not have polarizable electrodes. From FIG. 3, in the case of a load that requires a large current in the early stage of discharge, the electric double layer capacitor bears the large current load in the early stage of discharge, so that there is little drop in the discharge voltage.

Furthermore, since the battery electrode bears the burden of discharging at a steady current, a stable voltage can be maintained for a longer period of time compared to an electric double layer capacitor. In this way, since the characteristics of an electric double layer capacitor and a battery can be obtained with one battery, there is no need to connect the electric double layer capacitor and the battery individually as in the past, and the device can be made smaller and lighter.
