Embodiment Construction

[0034] Embodiments of the present invention will be described below, but the present invention is not limited to those described in the following embodiments, but can be appropriately modified and implemented.

[0035] figure 1 , figure 2A hybrid battery according to a first embodiment of the present invention is shown. Resin and conductive filler are added to the active material material that causes the battery reaction, and it is molded and hardened to form an active material molded body in the shape of granules, plates, blocks, rods, etc. In this case, the granular active substance can again be used by secondary molding. As the active material material that causes the battery reaction, all active material materials can be used regardless of the type of battery and the positive and negative electrodes. For example, in the case of a nickel-metal hydride secondary battery, nickel hydroxide powder, EVA resin, and conductive filler are mixed. Then, press molding is performed...

Abstract

The positive and negative electrode active materials having different charging / discharging characteristics, are placed in an electrolytic solution in respective cells interconnected through a separator.

Description

technical field [0001] The present invention relates to a hybrid battery in which an active material capable of high-speed charge and discharge and an active material capable of low-speed charge and discharge are combined as one battery. Background technique [0002] Japanese Patent No. 3051401 discloses a three-dimensional battery in which an active material is made into powder or granules. Also, a laminated three-dimensional battery is disclosed in International Publication No. WO00 / 59062. Also, Japanese Patent Application Laid-Open No. 2002-141101 and Japanese Patent Laid-Open No. 2002-141104 disclose a three-dimensional battery filled with a granular active material as a fixed layer. [0003] Existing secondary batteries use active materials with the same charge and discharge characteristics, and make batteries that can be charged and discharged with a large current but have a small battery capacity (high output type batteries) and those that cannot be charged and disch...
