By using graphite or graphitized carbon fiber (hereinafter collectively referred to as graphite materials) for the negative electrode, we can create high-performance chargeable and dischargeable batteries with high discharge voltage. This is what we provide.

低いこと、自己放電が大きいことなどの欠点があった。Previously, batteries that used carbon as electrodes used graphite (also called graphite) for the positive electrode and metal lithium for the negative electrode, but the voltage was too high and the solvent in the electrolyte decomposed. However, there were drawbacks such as low coulombic efficiency for charging and discharging, and large self-discharge.

。Another battery that uses activated carbon or activated carbon fiber for both the positive and negative electrodes has been proposed, but this has a voltage of about 2.
There were disadvantages such as low coulombic efficiency and low charge/discharge coulomb efficiency (Publication of Patent Publication No. 58-35881).

定した放電電圧を示す以外に、充放電におけるクーロン
効率が高い長所がある。The present invention is based on the discovery that by using a graphite material in the negative electrode instead of an activated carbon material, a stable discharge voltage can be exhibited at a significantly lower potential than the activated carbon material. This eliminates the drawbacks of batteries. When a graphite material is used for the negative electrode, it has the advantage of not only exhibiting a stable discharge voltage at a base voltage but also high coulombic efficiency during charging and discharging.

重なった層状構造をもち、この層間に充放電により電解
液中のイオンが入ったり、出たりすることが出来る。層
間にイオンが入る過程をド。In general, graphite materials have a layered structure in which six-membered ring network planar carbon layers are stacked in parallel, and ions in the electrolyte can enter and exit between these layers by charging and discharging. Describes the process by which ions enter between layers.

化合物が出来るのに対し、活性炭材料では層状構造を持
たないため、陽イオンのドープが起らず電解液相に電気
二重層を形成するにとどまるためと推測される。The reason why graphite materials exhibit a more base potential as a negative electrode than activated carbon materials is that graphite materials are doped with cations and form intercalation compounds, whereas activated carbon materials do not have a layered structure, so doping of cations occurs. This is presumed to be because no doping occurs and only an electric double layer is formed in the electrolyte phase.

るとづ−ばらしい性能を発揮するのである。Furthermore, when a graphite material is used as a positive electrode, the Coulombic efficiency is lower than when it is used as a negative electrode, presumably because anion doping is difficult to occur and side reactions occur. Graphite materials have poor performance as positive electrodes, but exhibit excellent performance when used as negative electrodes.

In the Raman beak 1-le by light (5145 people),
Characteristic Raman beaks appear near 1350 an-' and 1580 +i+-1 a'. As the graphitization of the carbon body J3 progresses, the peak around 1350c++i-' decreases, and the peak around 1580a++-' increases. Therefore, the ratio of the peak intensity of 1350CnI-1 to the peak intensity of 1580ao-' can be considered as an index indicating the degree of graphitization of the carbon body, and the smaller this ratio, the higher the degree of graphitization (F, Tui

For example, activated carbon has a peak l increase ratio of about 1, making it unsuitable for the negative electrode of the present invention, but highly graphitized polyacrylonitrile m fibers has a small peak ratio of 0.25 or less, and is therefore unsuitable for the negative electrode of the present invention. This highly graphitized carbon body can be used as the negative electrode material of the present invention.
