産業上の利用分野
本発明は電気二重層キャパシタの分極性電極と電池の正
極並びに負極を一体化したバイブリフト電池に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vibelift battery in which the polarizable electrode of an electric double layer capacitor and the positive and negative electrodes of the battery are integrated.
従来技術とその問題点
従来の電気二重層キャパシタは、活性炭電極表面への電
解液からのイオンの物質的吸着による電気二重層に蓄積
された電荷を利用することから、瞬時の大電流放電は可
能であるが電気容量は極めて小さい。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.
一方、電池は電気化学反応を伴うため、特に電解液に有
機溶媒を用いる電池においては、電極界面の抵抗が大き
く、大電流放電ができないという欠点があった。On the other hand, since batteries involve electrochemical reactions, they have the drawback that, particularly in batteries that use organic solvents for the electrolyte, the resistance at the electrode interface is large and large current discharge is not possible.
発明の目的
本発明は上記従来の問題点に鑑みなされたものであり、
大電流負荷で放電したときの放電々圧の低下が少ない、
長時間にわたって安定した電圧を維持することができる
ハイブリット電池を提供することを目的とするものであ
る。Purpose of the Invention The present invention has been made in view of the above-mentioned conventional problems.
There is little drop in discharge voltage when discharging with a large current load.
The object of the present invention is to provide a hybrid battery that can maintain a stable voltage for a long period of time.

体は変性ポリプロピレンである。The negative electrode current collector and positive electrode current collector are made of stainless steel foil, the polarizable electrode is an electric double layer capacitor made of activated carbon or carbon fiber, the negative electrode active material layer is made of graphitized carbon, and the electrolyte layer is a microporous membrane of polypropylene. It is made of an organic electrolyte, and the positive electrode active material layer is made of vanadium oxide. The sealing body is modified polypropylene.
電池構成は、電極面積が100cj、分極性電極の厚み

にはプロピレンカーボネートとジメトキシエタンの混合
溶媒に過塩素酸リチウムを溶解したものを用いた。The battery configuration had an electrode area of 100 cj, a polarizable electrode thickness of 50 um, a positive electrode active material layer thickness of 45 μm, and a negative electrode active material layer thickness of 30 am, with the active material layer disposed outside the polarizable electrode. 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.
集電体の周囲を封口材でシールレ電池を密封した。The Schiele battery was sealed around the current collector with a sealant.
尚、正極活物質は上記実施例のほか、マンガン、チタン

落ち込みが少ない。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.
又、定常電流での放電は、電池電極が負担するので、電
気二重層キャパシタに較べて長時間にわたって、安定し

池で電気二重層キャパシタと電池の特性が得られるので
、従来のように電気二重層キャパシタと電池を個々に接
続する必要がなく、機器の小型軽量化ができる。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.
